T 'i 256 Air System Equipment Air V*nt tod TatOatrn Ilirschinan-Pohle Co., Inc. Since 1908 200 Lent Ave. LeRoy, N. Y. Sales Representatives in Principal Cities Manufactuers of all types of Power and Gravity Roof Ventilators f >tj The Type "CKV" LOW PROFILE STATICK Power ventilator shown has been designed in response to the demand for the ABSOLUTE MINIMUM IN OVERALL HEIGHT for a ventilator using backward curved blade centrifugal fan, and is available in a wide range of capacities in belt driven sizes, with or without dampers or other extras as needed. The same LOW PROFILE type of housing is available using a propeller fan, or for gravity, pressure re lief or intake. The latter is available in oblong shapes or sizes as may be needed, with or without our Insulated Double Shell steel curb of one of the several standard types. Any or all of these ventilators subject to modification to meet the need of any building project. 4 Type LAC STATICK Power Roof Ventilator This model features the damper housing as an integral part of the ventilator where the damper is ac cessible for cleaning. It shows the electric damper control mounted in the motor chamber where it is also readily accessible because of the hinged cowl. Our Type "LAC" STATICK Power ventilator designed for efficient exhaust at either low or high static pressure using non-overloading backward curved blade centrifugal fan, available in many sizes for almost any required capacity. The Type "LC" STATICK Power ventilator (not shown) uses a similar construction minus the damper housing Capacity ratings for belt driven sizes of the Types "LC" and "LAC" STATICK Power ventilators have been formally approved by Air Moving Conditioning Association, and carry their CERTIFIED RAT I ING SEAL. i See Sweet's Architectural, Engineering, or Industrial Construction Files.

Jenn-Air Quiet-Tested Roof Exhausters are pre-proved under simulated field conditions. Each unit must pass rigid inspection by the critical Vt&rom'c Eye ... is "screened" in Jenn-Air's Sound-Elec Test Chamber to detect noise, vibration. Direct Drive Power Roof Exhauster Axial Roof Exhauster Dependable U-Spring Suspension virtually eliminates noise caused by vibration. U-Springs suspend the power assembly, isolate it from the base. Motor and wheel are balanced together, eliminating vibration and noise. Heavy gage all aluminum construction. The Axial type Jenn-Air Roof Exhauster is recommended for general ventilation work and for duct-type applications where static pressures do not exceed one-half inch. Special Non-Over loading Design protects against motor failures. Dependable U-Spring Suspension - eliminates noise caused by vibration. U-Springs suspend the power assembly; isolate it from the base. Belt Drive Power Roof Exhauster In this Quiet-Tested Belt Drive Power Roof Exhauster, Posi tive Weather-Proof Engineering is combined with trim Low Contour Design. Full Ball Bearing Drive and Motor are mounted out of the air stream. Heavy Gage All Aluminum Construction gives strength without weight- Exhauster can be quickly, easily, disassembled for re-assembly on the roof. NonOverloading Blade, dynamically and statically balanced, also assures long life, smooth, quiet operation. Hi-D Centrifugal and Axial Power Roof Exhauster Centrifugal Wall Exhauster Jenn-Air Centrifugal Wall Exhausters eliminate most duct work ... provide a means of ventilation through the wall when roof exhausters would prove unsuitable or more costly, as in multi-story construction. Constructed of heavy gage aluminum, exhausters are completely weather-proof, unusually quiet. De pendable U-Spring Suspension eliminates noise caused by vibra tion. U-Springs suspend the power asembly; isolate it from the* wall. This exhauster fills the need' for general area ventilation ... has a clean engineering design that features compactness and serviceability. The wheel (oentrifugal) or blade (axial) is lo cated at the top, providing a high point of discharge which allows low curb construction. Housing is made of heavy gage aluminum which provides strength without weight. Bird guard of heavy gage stainless steel construction comes as.an integral part of every unit. Unit opens easily for ready access to the drive assembly. Special vibration absorbers reduce noise to a minimum. Totally enclosed, full ball bearing, permanently lubricated motor assures smooth, uninterrupted service. Tubu lar drive assembly has permanently sealed, pre-lubricated ball bearings. Motor and drive can be serviced from interior of building, if desired. Jenn-Air Relief Vents eliminate goose necks or hoods used for air outlets or intakes. Weather resistant spun aluminum construction.
