30 cubic meter air purifier environmental testing chamber

30 cubic meter air purifier environmental testing chamberThis test bench is mainly used to simulate and detect the pollutant removal test of air purifiers.

This test bench mainly consists of a laboratory, clean air inlet, exhaust system, and sampling devicecompose.

Main components of the test bench

Laboratory composition：Test room, fluorescent lamp, ceiling fan, test bench, power socket, etc；

size：V=1400W * 1500H * 1400L ≈3m³；

leakage rate：<0.05；

Material:10mm tempered glass, stainless steel inner wall material, observation window equipped with collection and sampling holes；

Equipment installation:1. Top air intake, bottom exhaust on the side;

2. Install a sealed cabin door;

3. Reserved sampling and sampling holes (3+3)；

4. Install one ceiling fan and two 40W fluorescent lamps on the top;

Installation process:All connection parts are sealed with silicone rubber strips and glass silicone gel,

Ensure the airtightness of the laboratory

30 cubic meter air purifier environmental testing chamberThe overall equipment has a detachable function

Air inlet and exhaust device

Fan (technical parameters)：air inlet/Exhaust fan

material：The circulation pipes are made of stainless steel material;

Equipment installation: in progress/Add an air filtration system to the air outlet section

installation process：All connection parts of the pipeline are sealed with sealing strips and glass silicone gelThe detachable part is made of silicone rubber strips

Bolt tightening installation.

The natural attenuation test is as follows:

1) Place the air purifier to be tested on the test bench in the middle of the laboratory (except for vertical air purifiers), adjust the air purifier to the working state, check if it is running normally, and then turn off the air purifier;

2) Arrange the sampling points in a position that avoids the air inlet and outlet, with a distance of 0.5m from the wall and a relative height of 0.5-1.5m above the laboratory floor. One or more sampling heads can be installed at the same sampling point and connected to external sampling tubes;

Close the exhaust duct air valve, open the internal circulation duct air valve, start the auxiliary fan, and use a high-efficiency filter to purify the air in the laboratory, so that the particle diameter is Above 0.3 μ m
