Fiberglass Exhaust Fans
Fiberglass Exhaust Fans
GT Fiberglass Exhaust fans are designed to provide a full spectrum of ventilation requirements. The 12” to 72” Fiberglass Exhaust Fan Series covers a wide range of CFM performance and industry leading air movement and efficiency. The 72” is a high output and high efficient exhaust fan. This fan produces an astounding 65,000 CFM and 30 CFM/WATT at 0” static pressure. This large fan is variable speed with a variable frequency drive and can replace many smaller less efficient fans.

Product Specifications
Design
- When designing a proper ventilation system you want to transition from minimum ventilation to maximum ventilation as smoothly as possible. With our 72” fiberglass fan and our optional variable frequency drives you can smoothly go from 10,000 CFM to 65,000 CFM making it the most versatile fan in the market.
- Our 12”, 18”, 24”, 36” and 52” fans have excellent performance and efficiency.
- Fiberglass housings and cones are stronger and thicker than our competition.
- Fiberglass is a corrosion resistant and easy to clean surface. Our fiberglass discharge cones are designed not to stick out as far as conventional exhaust fans.
- Shorter cones are protected from snow and ice damage by most roof overhangs. The large cones on our competition work well in laboratory environments but do not perform as well outdoors, nor stand up well to the wind blowing against them.
- Our fiberglass fans series is ideal for tunnel or exhaust ventilation in greenhouse dairy, poultry, swine, factories and warehouses.
Technical Specifications
- Motor is 3 HP or 2.2KW on high and .3KW on low 230/460, 3 phase VAC.
- Belt drive runs 315 RPM on high and 80 RPM on low.
- Optional variable frequency drive.
- Outside dimensions 77” X 77” X 32”
