Ultraseal High Temperature HEPA filters are designed to meet the
critical filtration requirements of a wide range of applications
where airborne contaminants can cause damage in manufacturing processes,
equipment, or may cause health hazards.
Use where temperatures are above the operating limits of standard
Ultraseal High Temperature filters will maintain
maximum efficiency at temperatures of 500°F (260°C) continuously.
Ultraseal High Temperature filters are constructed
with either .050 thick aluminum or18 gauge stainless steel frames.
The filter pack consists of a continuous sheet of pleated glass
micro-fiber media. Corrugated aluminum separators maintain controlled
Both edges of the separators are hemmed to guard against media
damage. A box type pleat is utilized which allows the separator
to nest in the bottom of the pleat minimizing the chance of media
damage from the peaks of the corrugation. The filter pack, face
guard and frame sides are potted to the frame top and bottom with
high temperature RTV silicone sealant.
The pack is secured to the vertical frame sides using the same
sealant. The frame top, bottom and sides are also fastened mechanically
for additional strength. A silicone rubber gasket is supplied standard
on one side. U
ltraseal High Temperature filters are certified
to be a minimum of 99.97% @ 0.3 µm particles. Each filter is
individually tested in accordance with Mil Standard 282. The test
results, as to percent penetration and airflow resistance, are marked
on each filter.
