FANS AND VENTILATORS

Gravity Intake and Relief Ventilators

The Gravity Intake and Relief ventilators are non-powered and work on pressure differential between the inside and outside of the building.

Models FGI/FGR

FHI product photo Model FGI for intake and FGR for relief have the low silhouette Fabra Hood design. The Fabra Hood design is superior in appearance, load bearing strength, weather resistance, and dimensional flexibility..

Models GRS/GRSF

wih/grs product photo These spun aluminum ventilators are designed as intake or relief units for natural gravity or negative pressure systems. Model GRSI for intake and model GRSR for relief have an appearance to blend with other Greenheck products like Models G, GB, H-G, and H-GB. The model GRSF has a built in flashing flange for quick and easy installations without a roof curb.


Model WIH/WRH

WIH

These louvered penthouse ventilators are designed for where aesthetics are a concern. The housing is a louvered penthouse style that features extruded aluminum louvers. These models are designed for intake and relief applications for natural gravity or negative pressure systems. The louver design affords lower pressure drops while maintaining low hood heights and avoids the problem of detracting from architectural aesthetics. Their appearance blends with other Greenheck products like Models LDP, LBP, RSFP, and LSF.

Model RGU
