Crank Lock HEPA Filter Housing

Bulletin PB1604-0107

Important Features

• Choice of frame construction materials

• Stainless steel filter locking mechanism for

strength, durability and long-term integrity

• Access for up to four filters and prefilters wide

per door for quick filter changeout

• Double pin hinges enable the doors to make

level contact with the door gasket for a uni-

formly tight seal

General

C-3 and C-4 Side Access HEPA/ULPA Filter Housings

are designed for use with nominal 12 inch deep

HEPA/ULPA filters. They are factory-assembled

flanged units suitable for gel sealed or gasket sealed

HEPA filters. Both the prefilters and the primary

HEPA/ULPA filters are serviceable through the same

gasketed side access door.

Versatility

C-3 and C-4 housings may be used with Alpha 95 fil-

ters (95% DOP efficiency) and with Alpha Cell and

Alpha 2000 filters (99.97% and 99.99% DOP efficien-

cy). Standard housings accept nominal 12 inch deep

filters and 16” and 18” carbon adsorbers in a variety

of face sizes. They can be arranged from one filter

high and one filter wide to four filters high and eight fil-

ters wide. If large housings are not practical to rig into

place, smaller units may be stacked in the field.

Options

• Choce of frame construction materials

• Insulation

• Lifting lugs

• Transitions

• Static pressure ports

• DOP test ports

• High temperature modifications

• Weathercap

• Magnahelic gauges (mounted)

• PrefilterTrack

Construction

Housings are 24 inches deep in the direction of air

flow, (26 inches deep if it has a 4” prefilter section.)

and are constructed in your choce of frame materials.

Flanges are furnished for duct connections on the air

entering and air leaving sides. All joints are intermit-

tently welded and finished to remove all burrs and

sharp edges. The joints are then sealed with silicone

enabling the housing to withstand an internal pressure

of +/- 3.0 in. w.g.

The filter locking mechanism for the fluid gel seal-

model housing is a 300 Series stainless steel hand-

operated arm that moves the filter s gel-filled channel

on to the internal housing knife edge sealing flange.

The same mechanism also pulls the filter away from

the sealing flange when changing filters. The filter

locking mechanism for gasket seal-model housing is a

300 Series stainless steel and brass device. The

mechanism presses the gasketed filter against the

housing s sealing surface by means of a mechanical

bolt and thrust assembly that is manually operated

using a standard 3/4 inch socket or wrench.

Standard 2 inch or 4 inch prefilter tracks will accom-

modate pleated panel filters with efficiency ranges up

to 50% per the ASHRAE Standard 52.2 dust spot test

methods. Access doors have 0.5 in. thick closed cell

neoprene gaskets around the inside perimeter.

Double pin door hinges which pivot, allow the door to

make level contact with the gasket when closed.

Stainless steel wing nuts secure the doors.
