INTRODUCTION Loren Cook Company s Centri-Vane and Centri-Vane Stretch are constructed of aluminum and designed for straight-through air flow. Performance ranges from 5 to 31,2 CFM with static pressures to 6 w.g. The Centri-Vane belt drive is offered in 9 sizes from 12 to 36 and is available in duct mounted inline and roof mounted supply, exhaust and upblast configurations. The Centri-Vane direct drive is offered in 7 sizes from 8 to 2 in duct mounted inline configuration. Specially designed mixed-flow wheel provides unique performance with stable operation from free air to shutoff. True airfoil blades provide non-overloading horsepower characteristics. All aluminum construction reduces unit weight and associated installation costs. Adjustable mounting brackets permit mounting in any desired position. CVD Compact straight-through design saves valuable floor space compared to a conventional centrifugal blower. Straightening vanes insure linear movement of air at the fan discharge providing higher efficiency and lower overall noise levels. UL / cul 75 listing is standard on all Centri-Vane units. Models CVB and CVD are licensed to bear the AMCA Certified Ratings Seal for Sound and Air Performance. Model CVS is licensed to bear the AMCA Certified Ratings Seal for Air Performance.
