30m3 Environmental Test Chamber Specifications

The 30m³ environmental test chamber is constructed from low emitting and low polluting powder-coated insulated steel panels, based on the requirements in the following standards ASTM D6670-01, ANSI/AHAM AC-1:2006, JEM1467 and GB21551 3. The test chamber has HEPA filtered supply and exhaust air, along with recirculating ceiling and wall fans. The air in the test chamber can be conditioned to a broad range of temperature and relative humidity settings. The test chamber also has an independent air circulation system, which enables the control of the number of air changes per hour from as low as 0.05 to 1.0 and above. The ante-room is also supplied with HEPA filtered air, which is maintained at a positive pressure of approximately 20 kpa. UV lamps are used to sterilize the chamber environment. The air is supplied can be purged from the chamber enabling an air purity level after cleaning to be considerably above class 10,000.

Specialist monitoring instrumentation measures concentrations of suspended particulates and the levels of other harmful airborne pollutants such as allergens, viruses, mold, bacteria, volatile organic compounds (VOCs) and formaldehyde. Air samples can be collected remotely via sample ports at designated time points.

Our chambers are located in the centre of our facility and are surrounded by our molecular biology, microbiology, mycology, virology and allergen laboratories, thus allowing air and surface samples generated in the chambers to be rapidly processed and analysed.
