Loren Cook H Series Propeller Roof Ventilators are designed for industrial or commercial applications requiring a low profile roof top design. The H Series is available in exhaust, supply, reversible(*) or filtered supply configurations. It utilizes either the X.STREAM(**) high efficiency fabricated steel propeller for low and medium pressure applications or an extruded aluminum airfoil propeller for higher pressure applications

Exhaust, supply and reversible ventilators in sizes 20 through 48 and filtered supply ventilators in sizes 20 through 42 are shipped assembled. Exhaust, supply and reversible ventilators in size 54, and filtered supply ventilators in sizes 48 and 54, are shipped with the hood in two sections for easy field assembly.

* Direct drive only ** belt drive only

E-Series Extruded Airfoil Aluminum Prop

  • Designed for use where higher static pressures are required. It is constructed with six aluminum blades mounted in a cast aluminum hub. Pitch settings of the blades are set at the factory and are locked into place by means of a taper lock pin. It is available in diameter sizes from 24 inches to 60 inches with static pressures from 0 inches to 1 inch.

XStream-Series Steel Prop

  • Designed using the latest in computer technology, provides an optimum design for air flow, efficiency, quality and durability in a wide range of performance levels. High pressure capabilities and low noise levels are characteristic of the X.STREAM propeller. It is available in both low pressure and medium pressure models for either exhaust or supply in sizes 20 inches through 60 inches.
