Features9.2/10
Ease of Use9.3/10
Value8.9/10
Standout feature

Configuration saving and reuse keeps assumptions consistent across repeated centrifugal selections within Soler&Palau’s catalog.

Soler&Palau FanSelector organizes centrifugal fan sizing around the selection workflow engineers already use: set required airflow and pressure, then review the predicted operating point against available fan data. Results include key mechanical and performance outputs such as rotational speed and power demand, plus the context needed to judge whether the operating point sits in the feasible range. The tool also reflects Soler&Palau’s product coverage, so results are anchored to fans and options in the vendor catalog rather than a mixed-brand database.

A practical tradeoff appears when projects require cross-manufacturer comparison, because the selection set is tied to the Soler&Palau lineup rather than aggregating other brands’ curves. A strong usage situation is internal engineering review for equipment schedules where consistent fan selections and documented assumptions matter across multiple rooms or AHU modules.

How to Choose the Right centrifugal fan selection software

Centrifugal fan selection software is used to map airflow and pressure targets onto centrifugal fan performance curves so teams can converge on a duty point that matches the project operating point. This buyer's guide covers FanSelect, Soler&Palau FanSelector, WebFAN, FanScout, and Greenheck CAPS, plus SystemairCAD, QUALYFAN, Fan Performance Curve Generator Program, FanNet, and Fan Selector.

The selection workflow differences show up in how each tool handles operating point selection and configuration reuse across repeated calculations. The standout patterns across FanSelect, Soler&Palau FanSelector, and Greenheck CAPS focus on how conditions, power, and submittal outputs are produced for engineering handoff rather than just curve reading.

Centrifugal fan selection software for duty-point mapping, configuration reuse, and submittal-ready outputs

Centrifugal fan selection software converts centrifugal design inputs like airflow and static or total pressure targets into an operating point that can be validated against fan performance curves. Tools like WebFAN connect airflow and total pressure targets to performance curve outcomes in a single workflow so the duty point stays the center of the selection process.

FanSelect adds configuration-aware operating point selection by using catalog curve mapping with condition adjustments tied to the selected configuration. Greenheck CAPS ties the selection results to Greenheck submittal-ready outputs, including motor power and acoustic outputs, so the workflow carries forward into documentation and procurement handoff.

Centrifugal fan selection capabilities to verify in every tool

Selection software needs to translate airflow and pressure targets into a candidate fan duty point and then show how the computed point maps to the fan performance curve outcome. That matters because teams usually iterate around the operating point, not around isolated parameter guesses.

In this category, the differentiator is how the tool carries assumptions from selection through downstream engineering handoff like schedules and submittals. FanSelect, WebFAN, and Greenheck CAPS each treat the duty-point workflow as the core engine, but they attach outputs to very different handoff expectations.

  • Operating point logic tied to performance curve mapping

    FanSelect maps operating points from catalog curve mapping with condition adjustments tied to the selected configuration. WebFAN connects airflow and total pressure targets to curve outcomes within one duty-point workflow.

  • Configuration reuse for repeat selections

    Soler&Palau FanSelector lets engineers save and reuse configuration assumptions across repeated centrifugal selections inside its catalog. FanSelect uses configuration-aware condition handling so operating-point adjustments follow the chosen configuration family.

  • Submittal-oriented outputs including motor power

    Greenheck CAPS ties selection results to Greenheck submittal-ready outputs and includes motor power and acoustic outputs in one workflow. Soler&Palau FanSelector also outputs speed and power alongside the fan operating point for procurement-ready schedules.

  • CAD-ready schedule and drawing handoff

    SystemairCAD generates outputs aligned to engineering drawing and fan schedule handoff using Systemair catalog mapping. FanNet packages practical documentation for schedule and review cycles but provides fewer CAD or BIM oriented exports than engineering-first tools.

  • Curve-first iteration and validation checks

    QUALYFAN uses curve-driven duty-point selection tied to airflow and static pressure requirements and includes system resistance inputs for airflow and pressure checks. Fan Selector validates operating point selection against the selected centrifugal performance curve using fan-law style check logic for duty confirmation.

  • Batch revision support for many system variants

    WebFAN can require extra project setup discipline to automate large batch revisions across many system variants. Fan Performance Curve Generator Program focuses on reusable curve outputs for iteration rather than deep multivariant project automation.

How to choose centrifugal fan selection software for real duty-point workflows

Start by matching the tool’s selection engine to the way the engineering team thinks about duty points. FanSelect and WebFAN keep the duty-point computation at the center, while FanScout and FanNet narrow the workflow to manufacturer family scope or requirement-driven iteration packages.

Then pick the handoff shape that must survive internal and external review cycles. Greenheck CAPS and SystemairCAD concentrate on outputs that land quickly in submittals or CAD drawing sets, while other tools focus more on selection results than on downstream modeling depth.

  • Choose the duty-point engine model based on curve mapping behavior

    If the project must connect inlet and outlet condition definitions directly to the computed operating point, FanSelect’s catalog curve mapping with condition adjustments is the closer match. If the workflow must keep airflow and total pressure targets connected to curve outcomes in a single selection screen, WebFAN’s operating-point logic fits better.

  • Decide whether configuration reuse drives repeatability or whether single-pass selection is enough

    If repeat selections must keep assumptions consistent for schedules, Soler&Palau FanSelector’s configuration saving and reuse supports that pattern. If the team instead expects condition handling to follow the chosen configuration during curve mapping, FanSelect reduces rework by keeping those adjustments linked to the configuration selection.

  • Pick the output destination based on submittal and documentation requirements

    If the same workflow must produce Greenheck centrifugal selection outputs for motor power and acoustic items, Greenheck CAPS fits because it maps results to documented submittal-ready outputs. If CAD and drawing handoff dominates the workflow, SystemairCAD generates Systemair catalog mapping outputs geared to project documentation.

  • Validate system-resistance and condition coverage against the team’s input discipline

    If system resistance inputs are part of the validation steps during selection, QUALYFAN supports airflow and static pressure checks using system resistance inputs and curve-based duty-point selection. If validation needs are limited to confirming duty selection against a chosen curve, Fan Selector performs operating point validation using fan-law style check logic.

  • Align automation depth with batch revision volume

    If the organization must revise many system variants in batches, WebFAN automation can require extra project setup discipline, so selection data structures need to be planned. If the organization mainly iterates curve outputs and validates operating point shifts during design iterations, Fan Performance Curve Generator Program focuses on curve generation from entered duty conditions.

  • Confirm vendor library scope versus multi-vendor selection needs

    If centrifugal selections must stay inside a single manufacturer family for rapid drafting, FanScout’s ebmpapst centrifugal candidate workflow fits that constraint. If the project expects broader external handoff formats and multi-tool workflows, tools with clearer export pathways like FanSelect and WebFAN tend to reduce downstream friction.

Who benefits from centrifugal fan selection software

Centrifugal fan selection software is most useful when teams repeatedly translate duty-point requirements into curve-mapped candidates and then reuse the same assumptions across many design cases. That pattern shows up in HVAC design offices that run schedule iterations and in manufacturers who need submittal consistency.

The best fit depends on whether the team’s bottleneck is duty-point mapping correctness, configuration reuse, or documentation handoff outputs like motor power, acoustic outputs, or CAD-ready artifacts.

  • HVAC design engineers producing centrifugal fan schedules

    WebFAN and FanSelect keep duty-point selection tied to curve outcomes so engineers can iterate around operating point decisions with fewer manual correction steps.

  • Vendor-specific engineering teams working inside a manufacturer portfolio

    FanScout and Greenheck CAPS keep selection bounded to ebmpapst or Greenheck catalog content while producing outputs aligned to manufacturer workflows like candidate convergence or submittal readiness.

  • Engineering teams that must reuse assumptions across many repeated selections

    Soler&Palau FanSelector emphasizes configuration saving and reuse so repeated centrifugal selections keep assumptions consistent for submittal-ready schedules.

  • Design teams that deliver drawings and schedules through CAD-centric handoff

    SystemairCAD is built around Systemair catalog mapping to engineering outputs that reduce rework when generating fan schedules and drawings.

  • Teams that do iterative curve validation during early sizing

    Fan Performance Curve Generator Program supports generating performance curves from entered duty conditions so operating point shift can be validated against system resistance during iteration.

Common centrifugal fan selection mistakes

Selection errors usually come from mismatched assumptions rather than from incorrect arithmetic. Teams often enter duty inputs that represent the wrong condition boundary, or they treat configuration assumptions as throwaway values instead of selection inputs that must carry through to handoff.

Another frequent issue is assuming the tool’s exports or output packages match the team’s documentation pipeline. Some tools concentrate on selection accuracy while others concentrate on submittal and documentation outputs, so the handoff shape must be verified during tool evaluation.

  • Treating inlet and outlet condition definitions as optional during operating point mapping

    FanSelect ties condition handling to the computed operating point, so inlet and outlet definitions must match the design intent used in the selected configuration.

  • Planning multi-vendor selections without checking library scope boundaries

    FanScout and FanScout-style workflows stay inside manufacturer families, so multi-brand curve selection requirements will force workflow changes or duplicate projects.

  • Assuming submittal-ready outputs exist for the same downstream needs

    Greenheck CAPS produces Greenheck submittal-ready outputs including motor power and acoustic outputs, while tools like SystemairCAD focus on CAD-ready documentation outputs for Systemair projects.

  • Skipping export pathway planning for schedules and drawing generation

    FanSelect export and downstream handoff formats require extra step planning, so the export sequence must be validated against the target schedule or drawing pipeline.

Frequently Asked Questions About centrifugal fan selection software

How do FanSelect and WebFAN differ in operating point selection logic?
FanSelect starts from a requested duty, then maps the duty onto Ziehl-Abegg fan curves and adjusts for inlet and outlet conditions and losses to land on the operating point. WebFAN also targets the duty point, but its workflow is centered on connecting airflow and total pressure targets to performance curve outcomes and then producing export-ready results for fan schedule and specification use.
When should QUALYFAN be chosen over Fan Performance Curve Generator Program for curve-based sizing?
QUALYFAN fits teams that need repeated HVAC duty point checks tied to backward-curved impeller behavior while also doing system-side calculations for airflow and static pressure. Fan Performance Curve Generator Program fits cases where the main requirement is deriving performance curves from entered duty conditions so operating-point shifts across speed or operating changes can be reviewed.
Which tool keeps assumptions consistent across repeated centrifugal selections within a single manufacturer catalog?
Soler&Palau FanSelector stores and reuses configurations so the same selection assumptions persist across projects that use Soler&Palau’s catalog. FanScout and Greenheck CAPS focus more on family- and vendor-bound candidate selection and submittal outputs, but they do not center configuration reuse in the same way.
What breaks if a team needs cross-manufacturer comparisons instead of vendor-family selections?
FanScout and Greenheck CAPS are designed around ebmpapst and Greenheck product data, so cross-manufacturer comparison work becomes a manual process outside the tool. FanNet can speed duty-to-selection convergence, but it still relies on its installed fan data sources and documented handoff outputs rather than building a single unified comparison across multiple manufacturers.
How do Greenheck CAPS and SystemairCAD handle submittal artifacts and handoff output?
Greenheck CAPS ties selection results to Greenheck submittal-ready outputs, including motor power and acoustic outputs in one workflow. SystemairCAD generates package outputs such as schedules and drawings suitable for project documentation, with export formats intended for downstream CAD and document control.
What integrations or export formats are typically used for CAD or BIM handoff from these tools?
SystemairCAD produces export formats intended for downstream CAD and document control and supports generating fan schedules and drawings from its catalog mapping. FanSelect and WebFAN focus on export-ready selection results, but the practical integration path usually depends on the documentation workflow the engineering team uses after duty-point selection.
How do FanNet and Fan Selector support automation when multiple engineers must produce consistent schedules?
FanNet keeps the duty-first workflow tightly coupled to requirement inputs and outputs clear fan schedule handoff documentation, which reduces divergence across engineers. Fan Selector from iklimsoft.com supports configuration for common fan arrangements and validates the operating point against the selected curve, but teams still need governance around shared configuration inputs to keep outputs consistent.
When do centrifugal fan selection tools require administrative controls like RBAC and audit logging?
Organizations with shared configuration libraries typically need RBAC and audit log behavior to control who can change selection assumptions and who can export schedules, especially when selections are reused across projects. SystemairCAD and Soler&Palau FanSelector emphasize configuration reuse and documentation outputs, which increases the need for admin controls around configuration edits and approvals.
How should teams migrate existing spreadsheets into software workflows without losing selection assumptions?
FanSelect and FanNet both start from duty inputs that map to performance points and can be used to recreate the same operating-point basis as spreadsheet-driven selections, including checks tied to the selected curve behavior. QUALYFAN and WebFAN can also reproduce operating-point selection from structured airflow and pressure inputs, but migration work must include translating each spreadsheet’s inlet and outlet assumptions into the tool’s configuration inputs.
What tradeoff appears when curve-driven utilities prioritize speed over deep configuration management?
Fan Performance Curve Generator Program focuses on producing reusable performance curves from entered duty conditions, so teams get fast curve-driven checks but less emphasis on broad multi-project configuration management. FanNet and SOLER&Palau FanSelector prioritize handoff clarity or configuration reuse, so teams may trade off some curve-generation flexibility for stronger schedule consistency and workflow repeatability.
