Roof Exhaust Fans

Type Canada Blower JBH Up Blast Power Roof Ventilators

APPLICATIONS: American CoolAir JBH ventilators are designed for use in factories, warehouses, commercial buildings, machine rooms, where it is necessary for the fan assembly to be located above the roof, to discharge up and and to have low profile.

CONSTRUCTION: Canada Blower JBH ventilators are constructed to discharge vertically so that air velocity seals the opening against rain and snow. When the fan is off, counterbalanced fiberglass damper doors/flaps close by gravity to a weather-resistant closure and serve as a skylight. The motor and drive components are recessed into the roof curb. The ventilators utilize a cross-frame to support stationary shaft-bearing-cast aluminum hub assembly. Drive belt power is applied to the fan/hub assembly in the same plane as the bearings, reducing bearing load and increasing bearing life. Bearings are permanently lubricated and sealed. The six die-formed steel propeller blades are securely attached at three points on the hub. All Canada Blower blade assemblies are dynamically balanced.

An impeller is the central part of a centrifugal blower. It has a strong resemblance to the wheels found in a hamster cage. The rotation of the impeller pulls air into the blower, increases its movement, and changes its direction at 90o. The turning of the impeller creates constant air flow.

Canada Blower upblast power roof ventilators are designed to discharge vertically so that air velocity seals the opening against rain and snow while the unit is in operation. Whe fan is switched off, counterbalanced dampers close by gravity to provide a weather-resistant closure.

These roof exhausters are available in wide range of sizes and capacities: with blade diameters from 18" to 84" and capacities ranging from 1000 CFM to appr. 100,000 CFM. Fans of this type are quite efficient, dependable and require relatively little maintenance.

The Canada Blower JBH PRVs utilize a cross-frame to support unique bearings and fan shaft assembly. This stationary shaft mounts on the cross-frame member and power is applied directly to the prop hub in the same plane as the bearings. This reduces bearing load and substantially increases the fan bearing life. Bearings are permanently lubricated and sealed and have an L-10 life exceeding 300,000 hours. All roof exhaust fans are available with such accessories a motor-out-of-airstream kits, roof curbs, protective coatings, safety guards, spark-resistant and explosion proof ventilator constructions, and many other useful features.
