Fan Filter Units with Roomside Replaceable HEPA Filter & Light Fixture

CleanPro® GS LI 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.

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% efficneicy Filter is available as an option.

An acrylic eggcrate grille in an anodized aluminum frame is hinged to open, permitting removal of the filter without removing the unit from the ceiling.

The integral light fixture and T8 electronic ballast is located inside the filter housing below the final HEPA filter. This permits fluorescent light bulbs or ballast to be replaced easily from the roomside. A separate j-box for the lights permits various switching options.

The HEPA Filter is designed for 90 FPM average face velocity @ initial 0.47 w.g. and has a rated efficiency of 99.99% @ 0.3 micron or larger.

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.

• 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.
• Airflow ranges from 340 to 850 CFM for a 2' x 4' unit and 250 to 450 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.
• At average face velocity of 90 FPM measured 30" from face of filter, sound level is approximately 54 dba with less than 62 dba ambient sound level. Field conditions, voltage and method of testing could produce different results.
