IEC American Standard Air Volume Chamber Test Device

IEC Standard Compatible Electric Fan Performance Testing Device

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 testing device is designed based on the requirements for ease of movement and because the testing methods are largely similar, making it suitable for air volume testing of table 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 ones on the testing plane) to represent the average wind speed on the same ring.

2 Main Functions

Used for testing wind speed, temperature, humidity, electrical parameters (voltage/current/power/power factor), rotational speed, and time.
