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.

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
