Product Description

Product Description

Negative Pressure Aerosol Chamber is also called NPAC Aerosol Chamber and aerosol testing chamber.Scope of application: It is mainly suitable for the disinfection effect evaluation test of 1 m³ Negative Pressure Aerosol Chamber ,and the sampler is a liquid impact sampler.

 

Meet the standards

EPA and FDA GLP Compliant

The standard size for an EPA-regulated chamber is 10' x 10' x 8' (800 cubic feet).

Testing conducted in the NPAC(Negative Pressure Aerosol Chamber) simulates life size testing of whole 

room disinfection devices against aerosolized bacteria, fungi, or viruses.

Along with the large NPAC chamber, there are two additional smaller chambers, the cube and the 4′ x 4′.These two smaller chambers were designed to accommodate small devices, such as microbial samplers or air scrubbers. The cube measures exactly one cubic meter, this size allows for easier calculations to determine microbial counts in the air.

Cabin	Stainless steel cabin, the inner and outer walls are made of SUS304 stainless steel with a thickness of 1.0 mm; the middle is high-density PU foam, which has a good thermal insulation effect.
Inner bladder	The inner tank material is made of wide-format mirror 304 stainless steel, which is fully welded.
Door	Door size1000×1250mm(W×H), Single open fully sealed, sealed with PTFE strip sealant (HBC1079 food grade sealant has passed the EU ROHS environmental protection standard, passed the EU REACH chemical regulation standard, and passed the US FDA food hygiene standard).
Sealing material	With silicone rubber strip and glass sealant
Test phase	For the first group, according to the amount of disinfectant, spray hard water in a 1 cubic meter aerosol cabinet, and immediately use a liquid impact sampler containing 10 ml of neutralizing agent to sample for 10 minutes after the disinfection time. Draw 0.1ml of the test bacterial suspension and neutralize the solution, and count the viable bacteria. Take three groups in total.
Prepare bacterial suspension	Dilute with nutrient broth to a concentration of 5*102, bacterial suspension for testing.
