Flanders High Temperature Rigid Filter PB1003, Precisionaire PrecisionCell HT Specification Sheet
PrecisionCell HT
High Temperature Rigid Filters
Bulletin PB1003-1106
General
PrecisionCell HT filters are designed for high temperature applications up to 900
same rugged construction as the Gas Turbine
PrecisionCell. The HT version is manufactured of
specially selected components to meet high temperature requirements.
They are ideal for paint drying ovens or any application requiring high efficiency filtration at high temperatures. PrecisionCell HT filters are offered in two
high temperature operating ranges; 750
F and efficiency ranges of 65%, 85% and 95% per
ASHRAE Standard 52.1. Offered as a MERV 11-14
according to ASHRAE 52.2.
o
F. They feature the
ºF and 900º
Construction
The enclosing frame is manufactured of aluminized
steel, which is designed to eliminate spalling of corrosion inhibitors @ elevated temperatures.
The media pack is stabilized by a media pack
retaining bar and captured by faceguards upstream
and downstream. Grid strap bracing on the air
entering and leaving sides maintain the rigidity and
integrity of the PrecisionCell HT.
The media is designed for operation in high temperature applications and manufactured from one
continuous sheet of wet-laid micro-fine fiberglass,
which provides the required tensile strength and
operating pressure drop for these stringent applications.

Notes:
1. PD represents clean pressure drop in inches w.g. The recommended final pressure drop is 2.5 inch w.g.
2. Operation down to zero velocity is satisfactory for all models.
3. Efficiencies are average and are based on ASHRAE Standard 52.1 and 52.2 dust spot test methods.
Performance values stated may be averages typical of the products listed. Contact factory for actual performance test reports on specific products.
4. 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.
