NBF Exhaust Fans
NBF Fans are built to give years of heavy-duty, trouble-free service. Their rugged, belt-driven constructionoperates in any position, has permanently lubricated ball bearings and is available with single-speed, totally enclosed motors.
Combined with all-aluminum shutters and a heavy guage, galvanized steel wall housing (square box or sloped), the NBF Fan allows a maximum of unobstructed interior space. Fan and frame are coated with Coolair's new super-tough, baked powder polyester paint for years of long wear and low upkeep.
