Alfer Precision Fan Testing System

It is a fan test system established in accordance with ISO 5801 standards, in order to precisely extract the fan characteristics of the fans developed through R&D studies and to measure their performances precisely. Through the system;

  • Torque
  • Debi
  • Pressure
  • Temperature
  • Vibration
  • Humidity
  • Decibels

Measurements can be obtained

Fan performance can be measured over a much wider area as auxiliary fans are used in the system.

Fan efficiency can be measured with torque measurements up to 10.000Nm.


Flow ratei Max. 150.000 m3/h
Pressure Max. 30,000 Pa
Torque Meter Max. 10,000 Nm
The Board Engine 250kW

Alfer's Aerodynamic and Mechanical test Centre

Alfer Engineering is also a pioneer in its sector with the establishment of the "Fan Test Centre" within its own structure in accordance with ISO 5801.

Our test Centre tests the aerodynamic and mechanical properties of fans in real time under operating conditions.

These test rigs allow us to carry out mechanical and performance tests on fans, and with the torque meter we can directly measure shaft power, i.e., fan efficiency.

In this way, without waiting for the fans to be commissioned in the field, large-capacity fans are tested prior to shipment and all the necessary data is made available to the customer.


Flowratei Max. 1.200.000 m3/hour
Pressure Max. 30,000 Pa
Torque Meter Max. 15,000 Nm
Installed Motor 1200kW

Mechanical Tests and Non-Destructive Tests


In order to minimize vibration, static and dynamic imbalances of rotors of all sizes are eliminated, saving and continuity in use are ensured, malfunctions are prevented and efficiency is increased.


The rays penetrating the material affect the film on the other side of the materials on the other side of the materials, and then the internal structure of the material is controlled through the film subjected to the bathing process.

In addition;

100% Visual Testing (VT) is carried out on all our products by the Non-Destructive Testing Department (Non-DestructiveTesting-NDT) affiliated to our quality unit. In addition, the durability of the welds is ensured by performing Ultrasound Test (UltrasonicTesting - UT) on butt welds, Magnetic Test (MagneticTesting - MT) before and after stress relief in all critical welds, penetrant test (PenetrantTesting - PT) after root pass welds.
