Safety Cabinet - Laminar Flow Unit

Operation principle

The MCRT Safety-cabinet circulates 70% of  the contaminated air through one of the HEPA filters and exhaust remaining 30% of air flow through other HEPA filter. Incoming air laminar flows into the workspace with 0.45 m/s air velocity, providing absolutely clear work zone. CCA 30% of air exhaust out through outgoing HEPA filter, through remaining 70% to circulate. This air flow performance makes the system suitable for Biosafety level 1, 2, and 3.
