Gel Seal Style HEPA or ULPA Filter
Replaceable From Roomside
GS Terminal Diffusers are ideal for pharmaceutical companies, manufacturers of medical devices and companies in highly regulated industries. The GS series feature a gel channel on the upstream side of the final filter which provides a leak-free seal between the filter and the housing.
GS Terminal Diffusers feature a HEPA or ULPA filter replaceable from roomside while the filter housing remains in place.
The white powdercoated housing, fabricated from 20 gauge steel, is positively sealed to a hood fabricated from galvanized steel.
A 10″ or 12″ diameter inlet collar at the center of the filter hood allows for simple field connection to the main air supply using flexible duct.
The damper assembly is adjustable from within the room and is supported by a damper support channel permanently attached to the filter hood duct collar. A perforated damper disc is mounted on threaded rod and a guide provides screwdriver adjustments of the damper assembly from roomside.
Final filters are protected with a white epoxy diamond pattern grille and are tested according to accepted procedures as described by the Institute of Environmental Sciences (IEST) and/or ISO standards. The standard HEPA filter is 99.99% eff. and an ULPA grade 99.9995% eff. filter is available as an option.
A polystyrene eggcrate grille in an anodized aluminum frame is hinged to open, permitting removal of the filter without removing the unit from the ceiling. Optional perforated stainless steel or aluminum grilles are available.
