They turn much slower than centrifugal blowers (e.g. 3,600 rpm), and are often belt driven to facilitate speed changes. 5.3 Fan Performance Evaluation and Efficient System Operation System Characteristics The term “system resistance” is used when referring to the static pressure. Centrix is a centrifugal fan selection program that enables a fan manufacturer to select, design, cost and quote fans for applications. This program does in a couple of minutes what an experienced fan engineer would take many hours to design and cost! Over View: Selects fans from a range of designs to suit a volume and pressure. Centrifugal Pump Software. Our centrifugal pump software is a dynamic tool that accurately performs hydraulic selection and sizing of rotodynamic pumps. It is equally effective for special design pumps and standard pumps. With a rich database of liquids which can be extended by user, the software allows a huge amount of combinations of operating conditions, such as Flow Rate, Head, Temperature. The Computer-Aided Design ('CAD') files and all associated content posted to this website are created, uploaded, managed and owned by third party users. Each CAD and any associated text, image or data is in no way sponsored by or affiliated with any company, organization or real-world item, product, or good it may purport to portray. The software simulates the use of each type and size of fan. The software calculates diameter and width of the fan impeller. The software calculates the operating rotational speed. The software analyzes the performance and suggests the most suitable fans. The software generates a selection list with sorting and filtering capabilities.

RoVent10 - Fan Selection Software

With our new fan selection software RoVent10 an operating point specific fan selection can be made quickly and easily from over 2.900 fan models. The software is kept up to date through regular automatic updates. Please register RoVent10 after installation in order to use the full range of features.

The most significant innovations are:

• EasyFind: The simple introduction to the world of Rosenberg Fans. Find the right fan step by step.
• DirectFind: Enables you to find directly the fan by inputting of the article number or type.
• Product documentation: All required documentation of fans and accessories. For your planning this is also in the form of tender texts (DOC or TXT), which can be inserted as free text without formatting in your planning program. The character limit per line can be customized for the output.

Centrifugal Fan Design

Selfan is Comefri new selection program for axial fans. It allows selection of impellers for standard execution, vane-axial and counter-rotating. The fan can be chosen between the diameter/rpm options proposed by the software. Technical data, working curves, torque curve, Campbell diagram and noise spectrum are available and can be printed for all the proposed options.

BlackBox (32 bit) is the Comefri centrifugal fan calculation engine. It includes a dll library and XML data files.
The aeobb32.dll is a library of functions (developed with Visual C++) written for programmers who want to make applications to calculate air handling units using COMEFRI range of fans. The DLL can be used from C, Visual Basic or other languages; the aeobb32.dll accesses to data stored in XML files. In order to use the aeobb32.dll you need Microsoft MsAdo version 2.6 or higher.
The core of the application is a function library which allows to
Calculate fans for one fan family: the function finds out the most suitable fan according to the request data entered (volume, pressure, temperature, altitude, density, pressure and outlet opening types). The function calculates static and total performance, static and total pressure, operating point power, noise power
Get the fan configuration: the function extract the list of available accessories
Dimensional data of the fan: the function extract all dimension data.
