SAM MICROSOUND STAINLESS STEEL

All Stainless Steel Construction

Stainless Steel SAM MicroSound Series Fan Filter Units feature housings fabricated from #304 stainless steel with #4 brushed finish.

SAM MicroSound Fan Filter Units include a 99.99% efficient HEPA filter, 30% ASHRAE pleated type prefilter, 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.

The blower is a 115 volt low watt AC backward curved impeller, 60hz, single phase, permanent split capacitor type motor blower assembly with thermal overload protection. Other motor and voltage options are 208-230 (50/60 hz) and 277 (60 hz).

NCR Style final filters feature a stainless steel frame and are protected with a stainless steel round perforated grille on the downstream side.

SAM GS Fan Filter Units feature a HEPA or ULPA filter replaceable from roomside. Final filters inside the housing are standard GS style with anodized aluminum frame and upstream gel channel.

A round perforated stainless steel grille and frame assembly is attached with four (4) screws. Removing the grille permits replacing the HEPA or ULPA final filter without
removing the unit from the ceiling.

All final filters are tested according to accepted procedures as described by the
Institute of Environmental Sciences (IEST) and/or ISO standards.
