Welded Bevel Seal Frame
Extruded Aluminum Frames for Gasketed HEPA
Filter installations
The Bevel Seal frame is a factory welded, extruded
aluminum frame developed specifically for High
Efficiency Particulate Air (HEPA) filter installations.
Standard Bevel Seal frames accommodate multiple
sizes of gasketed HEPA filters 11-1/2" deep. (
See Fig.
2-116, 2-118 and 2-119.
)

leakage
The Bevel Seal frame features a two level sealing
surface connected by a bevel. This causes the filter
gasket to be compressed in two stages as clamping
pressure is applied. The outer edge of the gasket is
compressed to a greater degree than the inner portion of
the gasket. (
See Fig. 2-119.
)
In the event excessive clamping pres-
sure is applied, the individual cells in
the gasket material can be fractured
causing the gasket to relax, allowing
leakage.

Visual Control Filter Clamps
(See Fig. 2-117.)
hEPA Filter Applications
Visual Control clamps are designed for use with any
conventional gasketed HEPA filter. Located at midpoint
of each filter edge, the calibrated spring-loaded clamps
maintain up to 100 pounds pressure against the filter at
each clamping point. Four clamps are used per filter to
assure uniform pressure against the gasket. The clamps
have a 1-1/2" wide bearing surface.
Easy Clamp installation
No special tools are required for proper clamp
installation.
Tighten the bolt head until it is flush with
the clamp face to achieve the prescribed compression.
Proper clamping pressure is created indefinitely by the
calibrated spring.
Single filter clamps are used around the perimeter of the
frame bank. Double clamps are used along main runners
to secure a filter on either side of the T-section. (
See
Fig. 2-117, 2-118 and 2-119.
