CLEAN AIR PRODUCTS: The Series 305 horizontal laminar flow clean bench washes out particulates and prevents contamination from entering a clean work zone. The cabinet features "clean edge" construction that puts the hood and tabletop in shear with the media edge of the HEPA filter to reduce turbulence along the sides of the hood, improve laminar flow, and prevent contamination infiltration around the perimeter of the hood. The clean bench features a stainless steep table top with a white painted-steel shell, front access and interior lighting. Models are available for Class 100 or Class 10 environments. The unit can operate at or above ambient using makeup air for cooling, or it can have an air conditioning unit with reheat for temperature control at or below ambient.
