Ürün tanıtımı

This upblast fan covers 851-2808 CFM with a 3/4 hp variable-speed motor and a visibly larger 22 x 22 in curb cap. The increased wheel, motor section and roof opening distinguish it from the two 19 in-cap units. It suits higher-flow clean-facility exhaust and pressure control where a direct drive is preferred, subject to discharge separation and roof structural coordination.

Ana Özellikler

Largest selected roof capacity

The broader wheel and curb serve higher-flow exhaust zones without a belt drive.

Pressure-control modulation

Variable motor speed can track changing room or duct pressure demand.

Higher discharge elevation

The larger upblast assembly directs exhaust vertically away from the roof surface.

Applications

For larger cleanroom support exhaust, central laboratory ventilation and building pressure-control discharge systems.

Solutions for Your Application

Exhaust is re-entrained into a nearby outdoor-air intake.Coordinate discharge height, velocity, wind effects and separation from intakes using the final roof layout.

The larger 22 in curb conflicts with existing roof steel.Verify opening and support locations before ordering the curb and cutting the roof.

Mevcut Seçenekler

Confirm flow and static, voltage, controller, curb height, damper, disconnect, discharge accessories, coating and structural attachment.
