PrecisionCell GT

FOREMOST IN AIR FILTRATION

General

The PrecisionCell GT features extra heavy-duty
construction to meet the rigorous demands of gas
turbine rotary machinery air filtration applications.
They may also be utilized where extreme velocity or
turbulence have rendered other products to be inef­fective. PrecisionCell GT filters are available in
ASHRAE efficiencies of 60-65% and 90-95% in
either single or double header versions.

Features

The PrecisionCell GT offers a high dust holding
capacity for increased service life, eliminating cost­ly downtime and maintenance associated with filter
change out. The media is manufactured of a wet­laid, moisture resistant, dual layer micro-fine fiber­glass with high tensile strength and long service
life. The heavy gauge hemmed-edge corrugated
aluminum separators offer increased pack rigidity
with optimal pleat spacing.

Gas Turbine Rigid Filters

Bulletin PB1004-1106

The heavy duty corrosion-resistant steel frame and
expanded metal faceguards on both the air entering
and air leaving sides protect the media pack.
Retainer straps and faceguards on both sides pre­vent filter collapse and maintain rigidity in elevated
resistance situations and blow back from turbine
surges.

Notes:

1. PD represents clean pressure drop in inchw.g. The recommended final pressure drop is 1.5 inch w.g.

2. Operation down to zero velocity is satisfactory for all models.

3. Performance tolerances conform to section 7.4 of ARI Standard 850.

4. Performance values stated may be averages typical of the products listed. Contact factory for actual performance
test reports on specific products.

5. Perfmormance values shown in this publication may be averages or estimates intended to generally represent
product styles. Always contact factory for latest actual test data on specific Flanders Precisionaire models.
