SAM® Units & Accessories / 3-speed
GS Style Filter Data
The HEPA Filter is designed for 90 FPM average face velocity @ initial 0.47 w.g. and has a rated efficiency of 99.99%.
An anodized aluminum frame holds the 53mm media which is protected by a diamond pattern white epoxy coated steel grille. Final filters are replaceable from roomside.
Air Flow
Airflow ranges from 400 to 750 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.
Standard Ceiling Size
All 2’ x 4’ models are designed to fit a nominal 2’ x 4’ ceiling grid with a 22.5″ x 46.5″ standard opening.
Sound Level
At average face velocity of 90 FPM measured 30″ from face of filter, sound level is approximately 50-52 dba with less than 45 dba ambient sound level. Field conditions, voltage and method of testing could produce different results.
SAM MS 3-S Fan Filter Units provide quiet performance and economy while delivering 90 FPM airflow velocities, perfect for most cleanroom applications. Base design includes a 99.99% efficient HEPA filter, a prefilter and a 3-speed switch with an off position which disables the unit while servicing.
Housings are fabricated from steel with a white powdercoat finish and include seismic clip suspension points.
The 1/5 HP motor blower is a forward curved direct drive motor/blower assembly with isolation mounts. Units are available in 115 Volt (60 Hz) and 277 Volt (60 Hz).
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% efficiency and an ULPA grade 99.9995% efficiency filter is available as an option.
A polystyrene eggcrate grille in an anodized aluminum frame hinged to open is included, permitting removal of the filter without removing the unit from the ceiling. Optional perforated stainless steel or aluminum grilles are available.
