Comparison Table
Ziehl-Abegg Fan Selection
vertical specialistManufacturer selection software for centrifugal fans, motors, and air movement assemblies.
Selection reports generated directly from vendor curve behavior, reducing drift between computed operating point and submittal content.
Ziehl-Abegg Fan Selection is a centrifugal fan selection and documentation tool centered on matching fan performance to a specified operating point. It supports engineering workflows that include selecting fan speed and configuration, reviewing performance behavior, and generating selection documentation for handoff.
The software is tightly aligned with Ziehl-Abegg fan families and their published datasets, which reduces mismatches between curve data and the selected products. Output generation supports common design-review needs through exportable selection results suitable for project documentation and further calculations.
- +Fan-family selection is driven by vendor curve data tied to Ziehl-Abegg products
- +Selection reports consolidate operating-point results for design review
- +Workflow supports iterative tuning of speed and configuration toward the duty point
- +Exported results reduce manual transcription when building fan submittals
- –CAD-centric workflows like AutoCAD or Siemens NX integration are not a primary focus
- –Selection inputs stay inside the selection context instead of offering broad system-model extensibility
- –Cross-vendor comparison depends on inputting non-native data outside the built-in dataset
- –Automation options for batch runs and governance controls are not exposed as an obvious admin feature

Best for: Fits when projects need repeatable centrifugal fan selection and report exports aligned to Ziehl-Abegg product curves.
ebm-papst Product Selector
vertical specialistOnline product selection software for centrifugal fans, blowers, motors, and controls.
Interactive operating-point comparison with selection outputs packaged into reusable reports.
Product Selector uses an interactive selection flow that ties the requested operating envelope to candidate fan models and shows resulting operating points against system requirements. Performance curves and key operating outputs are available during selection, so teams can iterate on fan speed, pressure targets, and fit-for-duty outcomes without leaving the tool. Selection reports and exports support repeating the same decision basis for internal review and vendor-neutral coordination.
A tradeoff appears in workflow breadth, because the tool is centered on ebm-papst product data rather than acting as an all-vendor centrifugal fan modeling environment. It fits best when engineering teams already source ebm-papst hardware and need fast, traceable selections with consistent output files for procurement and specification writing.
- +Centrifugal fan selection workflow focused on ebm-papst performance data
- +Duty-point comparison during configuration supports rapid iteration
- +Selection reports and tabular exports help standardize handoffs
- +Inputs map directly to fan operating conditions used in design checks
- –Centric vendor catalog reduces cross-vendor comparison capability
- –Limited support for deep CAD-level configuration in the same workflow

Concepts NREC FANPAL
enterpriseMeanline and throughflow analysis tool for centrifugal fan and blower preliminary design.
Duty-point comparison ties candidate fan curves to system resistance so operating point shifts are visible during reruns.
FANPAL is a good fit for teams that need repeatable operating point analysis when airflow, pressure requirements, and efficiency tradeoffs change during design iterations. It supports centrifugal fan performance evaluation against system resistance inputs and uses standard curve-based selection behavior to show where the design will operate. The output set is oriented toward engineering review and handoff, including selection report exports that reduce manual transcription. The integration path is less about model-based automation inside CAD and more about exporting computed results into typical engineering documentation workflows.
A key tradeoff is that CAD-native geometry exchange is not the center of the workflow, so teams that expect tight Siemens NX or AutoCAD modeling loops may still need a separate process for geometry and duct layout. FANPAL works best when the team can standardize inputs for system resistance and acceptable operating envelopes, then rerun selections as design parameters shift. A common usage situation is commissioning a preliminary fan schedule for multiple operating cases and then using exported reports to guide procurement and electrical sizing decisions later in the project.
- +Curve-based operating point comparison supports fast iteration during design changes
- +Selection report exports reduce manual rework when preparing engineering documentation
- +Fan laws and affinity-law adjustments speed scenario testing without re-inputting datasets
- +Workflow stays aligned to centrifugal fan selection tasks and avoids unrelated features
- –Not designed as a CAD-native tool for Siemens NX or AutoCAD geometry workflows
- –API and automation surface for external systems is limited compared with engineering platforms

How to Choose the Right Centrifugal Fan Software
Centrifugal fan software supports operating-point selection using fan curve behavior against system resistance assumptions, with outputs prepared for design review and submittal-style documentation. This guide compares ebm-papst Product Selector, Concepts NREC FANPAL, and Greenheck CAPS alongside Siemens NX and AutoCAD integration needs across ten common centrifugal fan design workflow options.
The practical differences appear in how each tool packages duty-point comparison, selection report exports, and repeatable documentation for teams iterating on fan speed, operating condition, and system assumptions. The covered tools also vary in automation readiness for external workflows, including whether they offer an API surface that can support batch sizing or geometry-related handoff.
Centrifugal Fan Software for operating-point selection and selection-report export
Centrifugal fan software calculates candidate fan operating points by combining vendor fan curve data with a system resistance model, then records the resulting duty-point results in exportable selection documentation. ebm-papst Product Selector emphasizes interactive operating-point comparison with selection outputs packaged into reusable reports for faster iteration during configuration review.
Concepts NREC FANPAL uses duty-point comparison to tie candidate fan curves to system resistance so operating-point shifts remain visible during reruns. Greenheck CAPS focuses on selection report exports that align with Greenheck catalog configurations, producing structured documentation suitable for consistent manufacturer data handoffs.
Centrifugal Fan Software evaluation criteria for selection and submittal exports
Centifugal fan selection software must translate fan curve behavior and system resistance assumptions into a traceable operating point that teams can review and sign off. The differentiator is how each tool packages operating-point results into consistent selection reports that reduce rework during revisions.
Teams also need an automation and integration surface that matches their downstream workflow, including whether selections can be reused across configurations and whether outputs stay structured enough for document handoff. This guide prioritizes the practical mechanisms behind repeatable exports and configurable selection runs.
Interactive operating-point comparison for fast iteration
ebm-papst Product Selector enables interactive operating-point comparison and bundles the resulting selections into reusable reports for review cycles. Concepts NREC FANPAL emphasizes duty-point comparison tied to system resistance so shifts stay visible while rerunning candidate curves.

Repeatable product-family configuration mapping
Twin City Fan Product Selection ties configuration choices to Twin City product families so outputs map directly to exportable selection reports. Rosenberg Fan Selection Software concentrates on selection report generation that keeps operating points tied to shareable engineering outputs.
Decision framework for matching selection workflows, exports, and automation needs
Selection tools vary most in how they treat the selection session as a reusable workflow versus a one-off calculation screen. Tools that package duty-point comparison and report outputs together reduce manual copying when teams rerun operating conditions.
A second split happens around integration depth and automation readiness, since some products keep the workflow inside a vendor selection context while others are better suited for external orchestration. The steps below separate these philosophies so the choice follows the team’s actual delivery process.
Choose the workflow that matches how duty revisions are performed
If the design process relies on rapid reruns with visible operating-point shifts, prioritize ebm-papst Product Selector for interactive operating-point comparison and reusable reports. If the design process reruns duty conditions using system resistance ties as the primary explanation, prioritize Concepts NREC FANPAL because its duty-point comparison surfaces operating-point shifts during reruns.
Match report structure to the submittal style the project requires
If the project expects manufacturer-aligned submittal packaging, prioritize Greenheck CAPS because its selection report exports align with Greenheck catalog configurations. If the project workflow expects reports that stay tightly coupled to vendor curve behavior to prevent content drift, prioritize Ziehl-Abegg Fan Selection because its selection reports consolidate operating-point results driven by Ziehl-Abegg curve behavior.
Pick the tool that treats operating-point validation as part of selection
If operating-point validation against the fan-system operating envelope must be produced during selection for fewer curve-reading mistakes, prioritize Fansim for operating point checks tied to the envelope. If the operating-point workflow must explicitly connect system resistance inputs to the validation output for engineering review, prioritize CFturbo because its operating point analysis links fan curve results to system resistance inputs.
Decide whether duty envelope comparisons must be multi-point in one session
If recurring engineering tasks require duty envelope comparisons across multiple operating points without rebuilding the run, prioritize SoftInWay AxSTREAM because its operating point and fan-system envelope comparison supports repeatable multi-point runs. If the team’s duty revisions are managed through changes in fan speed with rapid feedback documented in outputs, prioritize FläktGroup Fan Selection because duty-point outputs include selected fan speed and resulting operating point documentation.
Branch by integration and automation expectations around CAD-native design
If the primary need is vendor-centric selection with report exports and CAD-native geometry generation is not a core requirement, consider Rosenberg Fan Selection Software because its focus stays on report-ready results tied to calculated operating points. If the team needs developer-facing extensibility beyond a vendor selection context, avoid tools with limited automation surface such as Greenheck CAPS and prefer ebm-papst Product Selector or Concepts NREC FANPAL where automation and integration readiness is positioned as part of the workflow.
Who should use centrifugal fan selection software in real design workflows
Centrifugal fan software fits teams that must convert fan curve behavior and system resistance assumptions into repeatable duty-point selections that survive engineering review. The right tool depends on whether selections are prepared mainly for manufacturer-aligned documentation or for iterative internal comparisons.
These software products also differ in how often they support external workflows like document generation pipelines and how much the workflow depends on vendor catalog context.
Mechanical engineering teams doing frequent operating-point reruns
ebm-papst Product Selector supports interactive operating-point comparison and reusable report packaging, and Concepts NREC FANPAL shows operating-point shifts tied to system resistance during reruns.
Project teams that require structured manufacturer-aligned submittal documentation
Greenheck CAPS produces selection report exports aligned to Greenheck catalog configurations, and Ziehl-Abegg Fan Selection generates reports tied to Ziehl-Abegg curve behavior to keep submittal content consistent.
Design teams that prioritize validation against the fan-system envelope
Fansim makes operating-point validation part of the selection workflow by tying the chosen operating condition to the fan-system envelope. CFturbo provides operating point analysis that connects fan curve results to system resistance inputs.
Teams that must map configurations directly to specific manufacturer product families

Mechanical teams running multi-point duty envelope comparisons for revisions
SoftInWay AxSTREAM supports multi-point runs for duty envelope comparisons within one workflow. FläktGroup Fan Selection documents operating-point results tied to selected fan speed to keep duty iteration traceable in outputs.
Common selection and documentation pitfalls when using Centrifugal Fan Software
A frequent failure mode is treating selection reports as interchangeable exports even when the tool’s configuration context changes how the operating point is computed and documented. Another failure mode is assuming CAD-native integration exists when the workflow primarily stays in vendor selection context.
The pitfalls below map to the concrete workflow behaviors seen across the top tools in this guide.
Using a selection output format that does not stay aligned with vendor curve behavior
When reports must match computed operating point behavior, prefer Ziehl-Abegg Fan Selection because its selection reports are generated directly from vendor curve behavior and consolidate operating-point results. If vendor catalog alignment is the delivery requirement, use Greenheck CAPS because its exports align with Greenheck catalog configurations.
Skipping operating-point validation during selection and relying on manual curve reading
Use Fansim when operating-point validation against the fan-system envelope must be produced during selection. Use CFturbo when validation must explicitly connect to system resistance inputs so engineering review can trace why a candidate passes or fails.
Assuming automation or CAD-native geometry workflow depth exists without checking the selection session boundaries
Expect CAD-native geometry workflows for AutoCAD and Siemens NX to be limited in multiple vendor-focused selection tools, including tools that keep the selection workflow inside a manufacturer catalog context. If external automation and batch sizing are a requirement, avoid tools that show limited automation around bulk scenario runs and prioritize ebm-papst Product Selector or Concepts NREC FANPAL based on their repeatable session packaging.
How We Selected and Ranked These Tools
We evaluated centrifugal fan selection software by scoring how reliably each tool produces duty-point operating results and exports selection reports that teams can reuse during revisions. Features received 40% of the weight because report packaging and operating-point workflows determine whether engineering teams redo work.
Ease and value each received 30% because configuration speed and how directly outputs support handoff affect day-to-day throughput. ebm-papst Product Selector led the rankings by combining interactive operating-point comparison with reusable reports built around ebm-papst performance data, which reduced drift between configuration exploration and review-ready documentation.
