Vertical Laminar Flow

Vertical Laminar Flow Unit is designed specifically for product protection. The Cabinet is a clean bench which provides ultra clean sterile HEPA filtered class 100 air in an isolated area for operations requiring a particulate-free environment where the highly sensitive process activities are carried-out.

The Vertical laminar air Flow Unit draws air in through the top of the unit through a pre-filter, through a plenum and vertically down over the work-surface and past the lap of the operator. It has the advantage of not pushing air into the face of the operator as in a horizontal laminar air flow cabinet. The laminar air flow cabinets are used for work with low-risk substances and materials, when protection of working material from environment is required or work with item requires a sterile working zone. Cabinets are used for equipment of local workplaces in medical, pharmaceutical and other institutes with high requirements for air cleanliness in the working zone.

Vertical Laminar Air Flow Unit is with a variety of standard dimensions also our unit can be custom engineered to any size. Laminar air flow available in powder coated Mild Steel, SS 304 / 316 / 316L or a combination of both.
