Laminar Flow Clean Bench Prevents Contamination from Entering Work Zone


Clean Air Products introduces the Series 305 Horizontal Laminar Flow Clean Bench. The Series 305 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. Bench length and height will depend on the specific process it is used for, but standard floor to table top height is 30 in. Standard widths are 2-1/2 in. over nominal 3, 4, 5, 6, 8 increments and the interior depth (interior table or working space) of 21.5 in. The overall cabinet width, depth and height will depend on the size of unit chosen. The clean HEPA-filtered air flows outward from the cabinet. This horizontal laminar flow air washes out particulates and prevents contamination from entering the 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. Top and bottom front grills recirculate the air within the bench. It provides recirculating temperature control to within ± *ºF. The unit can operate at or above ambient using make-up air for cooling, or it can have an air conditioning unit with reheat for temperature control at or below ambient.
