FRP Box Fan

*Unique exhaust fan with insulated fiberglass housing and shutters

*Products up to 100,000m³/hr

*Low energy consumption

Unique in concept, the FRP 72” box fan has been designed and built with superior methods and components. The fan housing and shutter assembly are constructed entirely of heavy duty fiberglass that ensures a proper seal, quiet operation with the greatest durability. The shutters can be opened manually or automatically (option) depending on the application. High quality insulation with an R value of 7.5 reduces thermal transmittance. The fan produces an impressive 100,000m³/hr.  The aerodynamic design and smooth surfaces ensures that the airflow is optimized. Coupled with a high efficiency 3 phase motor this fan delivers appreciable energy savings.  Designed with six (6) heavy duty stamped aluminum blades, mounted on a solid steel hub our 72’’ impeller is light en efficient.  The low speed capability makes this an excellent fan for cold climates. The shutter assembly can be used as a fan exhaust cover or as an air inlet for agricultural buildings. When used with our variable frequency drive to reduce belt and motor wear, the fan becomes one of the most versatile and reliable fans available on the market today.

※FEATURES AND BENEFITS

• On high speed produces 100,000m³/hr and 27 CFM/watt at 0” static pressure.

• On low speed produces 10,000m³/hr

• 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.
