Fans for Copeland EazyCool outdoor condensing units
The OM and OL units are fitted with a single-phase fan since the beginning of 2003, earlier manufactured units are
provided with a three-phase fan, models 120 and 270 depending on the condensing unit model.
Current used fans (model 121 or 271) are interchangeable with the previous models, but the wiring has to be
changed to single-phase wiring.
The OMQ and OLQ have a low speed (910 rpm) 6 pole single-phase motor.
Today, the condensers of the OM, OMQ, OL and OLQ units are equipped with single-phase fan(s).
The fan model is given in our Product Selection Catalogues and in Copeland Selection Software, both available on
www.eCopeland.com.
