30m³ air purifier Test Chamber HYQW-30-HYQW-30

30m³ air purifier Test Chamber HYQW-30


Product Description The 30m3 air purifier Test Chamber is made of 10mm float glass, sealed with low adsorption. The air purification system of inner chamber equipped with an air filter that removes particulate matter and chemical pollutants such as formaldehyde, benzene and ammonia. Moreover, Accurate temperature and humidity control, Good air-tightness, and low chamber background concentration . Meets standard GB/T18801-2015 air purifier GB/T18803-2002 Indoor air quality standard GB/T21551.3-2010 Particular requirements for air purifiers with antibacterial, bacteria-killingand purifying functions for household and similar electrical appliances IEC 62301:2005 Household electrical appliances – Measurement of standby power. EPA Energy star US Environmental Protection Agency Energy Star GB 4706.45 Household and similar electrical safety - Particular Overview of environmental test chamber The structure of air purifier Test Chamber is mainly composed of the chamber, air purificationsystemandtemperature humidity control system (external), exhaust air duct, circulation air duct, air samplingsystemandpollution source generating device. Testing Chamber It is composed of 304 stainless steel and glass, including background concentration control system, gas pollutant generator and testing device, temperature and humidity control system, etc. The inside dimensionis3500D×3400W×2500H mm, about 30±0.5 cubic meter.
