Kitchen style remote panels feature toggle switches and a stainless steel face plate for flush mounting to a wall. The junction box is also included.

Accessories

Special Coatings

Greenheck’s Permatector™ coating is available for a durable, long lasting finish. Decorative paints are also available in a variety of colors to match existing building fixtures. Consult your Greenheck representative for paint selections.

Roof Curbs

Factory provided roof curbs are available to ensure compatibility between the make-up air unit and roof curb. Standard construction is G90 galvanized steel.

Duct Adapter

Duct adapter is available with factory supplied roof curbs. The duct adapter allows for easy alignment of the supply duct connection.

V-Bank Filter Section

V-bank filter sections are available with 2-inch washable aluminum mesh or 2-inch 30% efficient disposable filters.

Weatherhood

Three weatherhoods are available: standard weatherhood includes birdscreen, filtered weatherhood includes aluminum mesh filters, and louvered intake hood includes a drainable blade louver at intake with 2-inch aluminum mesh filters.

Spring Vibration Isolation

Spring blower vibration isolators are available in lieu of neoprene isolators.

Exhaust Fan Starter(s)

Exhaust fan starters are available factory mounted and wired. Exhaust fan starters allow for an electrical interlock between the supply and exhaust fan(s).

Dirty Filter Switch

A dirty filter switch is available to monitor the pressure drop across the filter section. If the pressure drop across the filters is higher than the field adjustable setting, the dirty filter switch trips indicating the need to clean or replace the filters.

Freeze Protection

Electronic freeze protection is available to automatically shut down the supply fan when the discharge temperature is below the adjustable set point for an extended amount of time. This prevents the unit from discharging non-tempered air into the building and freezing pipes and other temperature sensitive items.

Inlet Air Sensor – Heat

The heating inlet air sensor will automatically turn the heat on and off based on the outdoor air temperature.

Motorized Dampers

Intake or discharge dampers are available to prevent backdrafts when the supply fan is not in operation. Intake dampers are factory mounted and wired. Discharge dampers ship loose for field mounting in the supply air duct.

Fiberglass Insulation

One inch fiberglass insulation is available to line the housing to prevent the formation of condensation and to form an acoustical barrier.

Double Wall Construction

An interior metal liner is available to isolate the 1-inch fiberglass insulation from the airstream.

Discharge Diffuser

Discharge diffusers are available as either 3-way for horizontal discharge or 4-way for downblast discharge.

Service Receptacle

A 115 volt GFCI outlet is mounted externally in a NEMA 3R box for the convenience of service personnel. A separate 115 volt power source is required.

Auxiliary Contacts

Normally open and normally closed contacts are available for supply fan status and supply fan interlocks.
