Industrial Grade Laminar Air Flow Machine has the feature that the environmental air is drawn by a centri balanced blower unit through pre filters and is thrown onto the work chamber through high efficiency filters retaining 99.97% or higher particulate and biological contaminants. The Machine is designed in such a way that the risk of entry of foreign and bio-hazard particles is minimized. The Machine has pre filters made using stainless steel or aluminium frames and are fabricated out of higher quality non-woven media, to minimize the risk of contaminants. The Industrial Grade Laminar Air Flow Machine has 65 db ±10% noise level and discharge rate of 90 CFM ± 10%.
