Electric Fan Air Volume Chamber Test System

Purpose: According to the technical specifications of BS EN IEC 60879:2019 and GB/T13380-2018:

1 Scope of Application (Applicable Standards)

This air volume test device is designed to meet the requirements for convenient operation and because the testing methods are largely similar, it can comply with the air volume testing requirements for desk fans, wall fans, floor fans, and column fans. It uses four anemometers to collect wind speed (adding two vertical anemometers to the original two horizontal anemometers on the test plane) to represent the average wind speed on the same ring.

2 Main Technical Parameters and Functions

2.1 Main Technical Parameters

Complies with the air volume testing requirements of GB13380-2018 and BS EN IEC 60879:2019 for desk fans, wall fans, floor fans, and BS EN IEC 60879:2019 for tower fans, bladeless fans, etc.

Laboratory dimensions: (small fan 6000*4500*3000) Unit: mm

2.2 Main Functions

Used to test wind speed, temperature, humidity, electrical parameters (voltage/current/power/power factor), rotational speed, and time
