The 3m3 Air Purifier Performance Test Chamber is mainly used for small (vehicle) purifier testing, to evaluate and measure the air purifier's test cabin for particulate matter and gaseous variable net air volume, and to accumulate cumulative cleanup detection.
3 m3 Air Purifier Performance Test Chamber
1, Stirring fan
2, Test prototype
3, Air filter
4, Air supply valve
5, Exhaust valve
6. Contaminant detection device
7. Contaminant generating device
8, Sampling port and sample port
9, Closed doors
10, Air conditioning air supply (and air supply when exhausting air)
11, Air conditioning return air (and exhaust)
Basic test project:
1. Smoke CADR test and analysis system
Refer to the AHAM AC-1 standard to test the CADR value of smoke and visually evaluate the purification performance of the purifier on particulate matter (including PM2.5). Refer to GB/18801 Air Purifier Test Project
2, formaldehyde purification efficiency test
Tested in a 3 cubic meter test chamber, 1 to 6 hours of formaldehyde removal efficiency.
3, VOC purification performance test
Test VOC (toluene) removal efficiency in 1 cubic hour of test chamber in 3 cubic meters.
