SAM® Units & Accessories / 3-speed
NCR Style Filter Data
The HEPA Filters are designed for 90 FPM average face velocity @ initial 0.47 w.g. and have a rated efficiency of 99.99% @ MPPS. An anodized aluminum frame holds the 53mm media which is protected by a diamond pattern white epoxy coated steel grille.
Final filters can be replaced by removing unit from ceiling, placing on a bench, removing and replacing the filter and re-installing unit in ceiling.
Low Profile
All SAM MicroSound NCR Style Models are 12-5/8″ high.
Air Flow
Airflow ranges from 500 to 750 CFM for a 2 x 4 unit and 400 to 750 CFM for a 2 x 2 unit. At 90 FPM, CFM is nominal 632 on a 2 x 4 and 300 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 62-52 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 a ULPA grade 99.9995% efficiency filter is available as an option.
Other popular options include an 8’ power cord (115 Volt only).
