Unit Cooler
The new S1G305 series uses 30% less power than typical unit cooler fans with PSC
motors. Specifically designed for unit cooler applications, the S1G305 fan series is
equipped with a very efficient electronically commuted, permanent magnet motor. Motor,
blade, power cable and three mounting options are integrated and available as a single
part number. The S1G305 fans are equally suited for both OEM and retrofit use.
Fan replacement or retrofit of walk-in evaporators is a breeze with the winning combination
of wide voltage range and rotary speed selection on the S1G305 series!
