Ideal for pharmaceutical companies, manufacturers of medical devices and companies in highly regulated industries. The SAM GS units feature a gel channel on the upstream side of the final filter which provides a leak-free seal between the filter and the housing. They feature a HEPA or ULPA filter replaceable from room side while the filter housing remains in place. The housings are fabricated from steel with a white powder coat finish and include seismic clip suspension points. The energy efficient N310 motor blower is a low watt backward curved impeller, single phase, permanent split capacitor type motor blower assembly with thermal overload protection. They include a 99.99% efficient HEPA filter, 30% ASHRAE pleated type pre-filter, seismic clip suspension points, safety switch which disables the unit while servicing, and solid state variable speed control with RFI suppression, allowing the airflow to be fine tuned. 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. A polystyrene egg crate grille in an anodized aluminum frame is hinged to open, permitting removal of the filter without removing the unit from the ceiling.
Benefits & Features
Ideal for Pharmaceutical CompaniesGel Seal Style HEPA or ULPA FilterReplaceable From Room sideThe standard HEPA filter is 99.99 percent eff.ULPA grade 99.9995 percent eff. filter is an available optionOptional perforated stainless steel or aluminum grilles are availableOther popular options include an 8 foot power cord (115 Volt only), 99.9995 percent eff. ULPA grade final filter, UL 900 filters and duct collar adaptersGS-Style Filter Data: The HEPA Filter is designed for 90 FPM average face velocity at initial 0.47 w.g. and has a rated efficiency of 99.99 percent at 0.3 micron or larger.
Access Port: This port is located in the center of the filter element face and is used for introducing an upstream challenge or measuring static pressure.
Standard Ceiling Size: All 2ft X 4ft models are designed to fit a nominal 2ft X 4ft ceiling grid with a 22.5” X 46.5” standard opening.
Air Flow: Airflow ranges from 340 to 640 CFM for a 2 x 4 unit and 220 to 340 CFM for a 2 x 2 unit. At 90 FPM, CFM is nominal 510 on a 2 x 4 and 220 on a 2 x 2 unit respectively. Airflow for units running at 50 Hz will be about 20% less.
Sound Level: At average face velocity of 90 FPM measured 30” from face of filter, sound level is approximately 54 dba with less than 45 dba ambient sound level. Field conditions, voltage and method of testing could produce different results.
