Gasket Seal
GASKET SEAL DESIGN CONCEPT
The filter to housing gasket seal is effected by means of a continuous
flat mounting surface on the interior of the housing, which mates to
a perimeter gasket on the filter. To affect the seal, the locking
mechanism forces the filter against the mounting surface.
OPENING AND CLOSING GASKET-SEAL LOCKING
MECHANISM
By turning the drive bolt(s) clockwise (located at the front exterior
of the housing), independent pressure bars with preloaded springs,
(located in the filter locking mechanism), force the filter against the
interior-mounting frame (there are two drive bolts per filter).
Preloaded springs on each pressure bar, for each filter element,
apply consistent pressure to maintain filter seal. The applied force
has a minimum clamping load of 1,400 pounds per perimeter of the
filter. This force should be applied as an even, uniform load along the
top and bottom of each filter frame. The gasket shall be compressed
to and not exceed 1/8.”
Caution:
Over compression of the gasket can lead to leaks.
The standard locking mechanism hardware is 18-8 stainless
steel with a 360 brass nut.
