Roof Mounted Air Intake or Exhaust Housing units serve frequently as gravity ventilators, pressure relief units, fan discharge caps, spillways, fresh air intakes, and sight shields (for aesthetic purposes) for roof mounted equipment. The Silhouette of the Pennhouse is compatible with the Linea centrifugal exhauster line. This serves to maintain architectural harmony where units of both types are required on the same roof.

Weather Caps for Air Exhaust or Intake are used as pressure relief ventilators, discharge caps at the end of ductwork, or oustside air inlet hoods. Their aerodynamic design and large diameter caps minimize pressure drops and air noise. Two available models WCF (weather cap flat) and WCC (weather cap curb).

Gravity Ventilator | PT, HPA, PA

Gravity Ventilators offer the Turbine, Pul-Air and Insul-Air models. Turbines are ideal for the general ventilation of factories, farm and agricultural buildings, commercial and public structures and homes. The Pul-Air is a simple device designed to permit an easy outward flow of air with no internal obstructions or moving parts to require maintenance. The Insul-Air is the ideal choice where an extended airshaft is necessary, to clear the peak of a roof for example. It features all the sturdy construction-details of the Pul-Air plus an extended airshaft and an integral flat mounting base.
