TPI Corporation Shutter Mounted Direct Drive Exhaust Fans

Description

OSHA workplace air exchange standards mandate positive mechanical ventilation inside commercial workshops, barns, and storage facilities. The TPI Shutter Mounted Exhaust Fans exhaust stale heat, moisture, and fumes through building walls. It mounts directly into exterior wall openings, requiring field framing and hardwired electrical hookups that eliminate simple plug-in portability.

Heavy aluminum constructs the self-closing exterior shutter louvers, fitted to an all-welded structural steel frame with powder-coated wire guards. An enclosed totally enclosed air-over electric motor draws 2.2 full-load amps on standard 120V 60Hz single-phase wall circuits, driving three aluminum blades. Total dry unit weight measures 24 lbs. Exterior frame dimensions measure 21 inches wide, 21 inches tall, and 12 inches deep to fit standard framing.

Key Features of TPI Shutter Fan

Maintenance directors buy TPI Shutter Fan units to exhaust heat, humidity, and chemical fumes from paint prep areas and commercial equipment rooms. Equipment pricing provides an all-in-one fan and shutter package that eliminates separate exterior louver installations.

• Integrated aluminum gravity shutters open when the fan starts and snap closed when the motor stops.
• Balanced aluminum fan blades exhaust up to 3,100 CFM of hot air through exterior building walls.
• Totally enclosed air-over motors protect internal copper windings from airborne dust, rain, and humidity.
• Heavy structural steel mounting frames slide straight into standard rough wall openings without custom flashing.
• Rear steel wire safety guards prevent accidental contact with spinning blades from inside the room.
• Direct-drive motor configurations mount blades straight to the motor shaft, eliminating drive belt adjustments.
• Permanently lubricated ball bearings provide smooth rotor rotation without requiring routine oil service.

Airflow Shutter Static Bench Metrics

Airflow bench evaluations confirm 3,100 CFM output in free air at 1,725 RPM rotor speed. Aluminum shutter louvers swing to full ninety-degree open positions under 0.12 inches of water-gauge air pressure. The TEAO motor runs cool, with case temperatures rising just 26 degrees Fahrenheit above ambient during eight hours of continuous duty testing. Current draw stabilizes at 2.1 running amps on 120V circuits with zero motor overheating. Operating sound meter tests record 65 dB at ten feet away from the shutter face.

Wall Framing Usability Realities Maintenance

Installing this 24 lb fan takes one worker driving lag bolts through the pre-punched steel frame flange into exterior wall framing. Electricians must hardwire power to the motor conduit box. Do not buy this shutter fan for Class 1 Division 1 explosive gas rooms, spray paint booths, or grain dust elevator shafts.

• Blow dust and cobwebs off the aluminum shutter louver hinges once each month.
• Wipe industrial grease and grime off the fan blades every three months.
• Check motor mounting bracket bolts for vibration loosening twice per year.
