Description

Suited for ventilation of tanks, process vessels, or other confined spaces for the removal of hazardous fumes or contaminated air from welding, sandblasting and other operations. Rated operating pressure 40-110 psi. Hi-tech four blade design allows for lower RPMs while still moving more air. Bearings are packed with a hi-tech synthetic lubricant for longer life. Fan Blades are precision balanced. Electro-polished stainless steel fan guards. Castings are heat treated to T6 aircraft aluminum specifications. Super-duty, high quality, high pressure air seal for longer service. Heaviest-duty fans in the industry. Guide vanes eliminate turbulence which smooths air flow and increases effeciency.

The unit consists of a rugged cast-aluminum housing and a cast-aluminum fan blade. The shaft, bearings and fan blade are the only rotating parts. There is no torque on the shaft, as it does not transmit any power to the fan blade, as shafts normally do. The compressed air jets on the trailing edge of the blade drive the fan. The fan has a hub and four blades which produce adequate static pressure to overcome the resistance of the system to be ventilated. Only two of the four blades have jet outlets. All have airfoil cross sections for higher flow rates. Guide Vane attachments are used to increase the fans effeciency. They neutralize the air spin past the blades and guide the air flow into an axial direction. This four-blade design produces higher air flows at lower RPM’s which increases bearing life. It can be used as a blower or exhauster.

An optional adapter plate (TX-JFBFA) can be purchased for use with Butterworth Flanges onboard ships. See picture of optional flange. Performance tests were conducted at a independent test lab to AMCA Standard 210. Shipped with grounding cable for safety and crowfoot connectors.
