* Data is based on standard units and normal conditions 100deg. Tr maximum. For non-standard units and/or application consult with local representative or the factory.

** Based on standard air(70 deg F and 14,7 psi) with discharge nozzles or equivalent 1/4"W.C TESP.  use total External Static Pressure column that will overcome total system resistance.  Approximate pressure drop for component and accessory items   : filter (dirty) 1/4", intake hood 1/8",birdscreen 1/8",discharge louver 1/4". Damper resistance may be ignored.

& Based on standard air capacity. Check factory for optimum applications

&& Approximate weight of basic unit with standard motor.
