Frequently Asked Questions View all FAQs
How do you order the correct replacement parts?

Before ordering replacement parts, make sure you have the fan model and serial number.

Where can I find instructions to wire a motor on my fan?

The nameplate of the motor includes a wiring diagram. Wiring diagrams can also be found beneath the motor image in our Buy Parts section. Simply click the wiring diagram icon to view it.

Can I install a thermostat?

Yes, but only if the thermostat has a simple on/off operation. Please note: if the thermostat varies the amount of voltage delivered, it will damage the motor and void the warranty.

Can I install my whole house fan vertically?

Comfort Cooler (CC) series whole-house fans may be mounted vertically, however, the AS and CSS shutters will not function properly in the vertical position. We do not carry a ceiling shutter for vertical installation. Vertical installation instructions.

When you need big air aimed exactly where the work is, Triangle Engineering’s HBPC series delivers. Built on our PC series platform, the HBPC adds a heavy‑duty cradle that tilts the portable drum fan up or down for precise, directional airflow. The cradle and pivot hardware are beefy, industrial‑grade components designed to stand up to daily bumps, transport, and continuous duty in harsh environments. Available in 36″, 42″, and 48″, these direct‑drive drum fans move 10,900–19,100 CFM (size/HP dependent) to cool people, products, or heat‑prone equipment. A full barrel‑width handle and two large wheels let you tilt back and roll into position fast. Standard units include 115 V single‑phase with cord and molded plug, with 230 V single‑phase and 3‑phase models available. With single‑speed models (and 2‑speed available on ½ HP) and readily available replacement parts, HBPC keeps your floor productive with low maintenance and high‑velocity performance.

  • Heavy‑duty cradle & pivot – reinforced steel cradle with positive tilt control is built to handle industrial use and rough transport.
  • Multi‑directional aiming – tilt up for overhead flow or destratification; tilt down or level for spot cooling across work cells and aisles.
  • Full‑width, easy‑grip handle + two large no-flat wheels – tilt back and go; simple, stable positioning.
  • Direct‑drive reliability – no belts or pulleys to service.
  • Deep‑pitch steel blades – deliver high‑velocity, high‑volume air movement.
  • Heavy‑gauge painted‑steel barrel with OSHA spiral‑wound guards – durability and safety in one package.
  • Roll‑formed “ogee” barrel profile – adds rigidity and resists drum deformation.
  • Protected switch housing – barrel‑mounted control sits behind a steel guard.
  • Facility‑friendly power – 115 V 1‑ph cord & plug standard; 230 V 1‑ph and 3‑ph available.
  • Service made easy – replacement parts are readily available for quick shipment and minimal downtime.
  • Blade diameters: 36″, 42″, 48″
  • Airflow range: 10,900–19,100 CFM (size/HP dependent)
  • Motor horsepower: ½ HP (single‑speed standard; 2‑speed available) or 1 HP
  • Motor type: Open Drip Proof (ODP) or Totally Enclosed (TE)
  • Electrical: 115 V 1‑ph with cord & molded plug (standard); 230 V 1‑ph and 3‑ph models available
  • Drive: Direct drive with sealed bearings — low maintenance
  • Mobility: Two large no-flat wheels; tilt‑back transport via full‑width handle; heavy‑duty cradle for directional aiming
  • Safety: OSHA‑compliant front & rear guards; steel switch guard over barrel‑mounted switch
  • Precision spot‑cooling on assembly lines, welding bays, and CNC cells
  • Destratification — tilt upward to mix hot ceiling air with cooler floor air and even out temperatures
  • Welding & fabrication support — position to pull fumes away from the weld zone without blowing directly on the arc (supplements local exhaust; not a substitute for code‑compliant fume extraction)
  • Warehouses, cross‑dock lanes, and packaging areas
  • Auto service bays, aviation hangars, and equipment maintenance shops
  • Event/rental fleets, restoration, and temporary cooling
  • Aim airflow precisely – directional cradle with positive‑tilt pivot puts high‑velocity air exactly where you need it: up for destratification, level across aisles, or down onto equipment.
  • Built for industrial abuse – heavy duty steel cradle and reinforced pivot hardware, paired with the roll‑formed “ogee” barrel, stand up to daily moves, bumps, and continuous duty.
  • Easy to move and position – full‑width handle and two large no-flat wheels; tilt back and roll into place quickly and safely.
  • Lower maintenance – direct‑drive motor with sealed bearings means no belts or pulleys; guarded barrel‑mounted switch resists accidental hits.
  • Versatile on the floor – from personnel and process cooling to assisting fume direction around welding (pulls fumes away without blowing on the arc) and temporary ventilation.
  • Power flexibility – 115 V single‑phase standard; 230 V single‑phase and 3‑phase models available for facility standards.
  • Fast parts support – readily available replacement parts ship quickly to minimize downtime.

Fabricated, assembled, and performance‑tested in Jacksonville, Arkansas, using a blend of domestic and globally sourced components—backed by Triangle Engineering’s fast parts support and decades of industrial ventilation expertise.
