GT Fans are designed to provide a full spectrum of ventilation requirements.  The 12” to 72” Fiberglass Exhaust Fan Series cover 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 72” 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.  By replacing many smaller fans you can reduce your installed cost and save on electrical operating and maintenance cost.  The 72” also gives you more CFM per fan size than any other fan.  Less fans mean less cost and more light in your greenhouse.

 

12” – 36” FEATURES
• Balanced 3 paddle blades.
• Corrosion resistant aluminum base mount.
• Direct drive maintenance free motors.
• Energy efficient.

52” FEATURES
• Balanced 52” heavy duty cast aluminum blade with a Lifetime Warranty.
• Available 1 HP and 2 HP motors.
• Cog (AX) Belt drive with automatic tensioners.
• Hot dipped galvanized motor mount and base.

72” FEATURES
• Balanced 72” heavy duty corrosion resistant 6 paddle aluminum.
• On high speed produces 65,000 CFM and 30 CFM/watt at 0” static pressure.
• On low speed produces 10,000 CFM and 30 CFM/watt at 0” static pressure.
• Optional variable frequency drive allows you a smooth speed adjustment from 300 RPM down to 80 RPM. Fan power consumption reduces with speed. Make sure you have a minimum shutter opening on low speed of 1”.
• 72” fan performance independently tested.

 


Applications
• Great air throw pattern for heat de-stratification.
• Ideal greenhouse spacing 50’, but call your Green-Tek ventilation engineer for proper design recommendations.
• Air de-stratification in buildings can reduce heating and cooling bills by
up to 35%.
• Ideal for Greenhouses, Industrial and Agricultural applications.
• Create an air exchange when placed in a wall.
• Low horse power motor means low energy cost.
• Machine, people and compressor cooling.
• Heat stress relief.

• Insect control when creating an air velocity of 300 FPM or more.

    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.

    • Belt drive runs 315 RPM on high and 80 RPM on low.
    • Optional variable frequency drive.
    • Outside dimensions 77” X 77” X 32”
