• Large face area centrifugal fan
• New “bolt-on” coil for maximum capacity in a minimum
space.
• Electronically balanced high efficiency fans with forward
curved blades provide quiet operation.
• Heavy gauge galvanized steel cabinet.
• Self-aligning ball bearings and heavy channel stiffeners
eliminate vibration and ensure quiet operation.

* For Applications in room temperatures above 35 °F (1.6 °C) maximum face velocity should not exceed 500 FPM
(152m/min) and capacities corrected accordingly (see table 1 for correction factors).
** These ratings are based on moderate coil frosting. For heavy frosting use factor of 0.95.
FACE VELOCITY CAPACITY CORRECTION FACTORS
(1) “T.D.” - Represents the difference between temperature
of air entering cooling coil and coil refrigerant temperature.
Ratings for units using electric defrost may be determined by
multiplying ratings in above table by 0.95
