AIR HANDLER - VARIABLE SPEED
The Steffes Air Handler includes a return plenum, supply air
blower, water coil, and air filter.
The air handler’s variable speed blower incorporates an ECM
motor that automatically adjusts its speed to achieve the appropri-
ate CFM for the thermostat input received. Benefits include:
w Quieter operation
w Better dehumidification
w Offers greater operating efficiency by consuming 25% less
energy during normal operating mode which provides for
operating cost savings to the consumer. In continuous fan
mode, low speed energy savings can be greater than 70% in
comparison to a standard fixed motor speed.
w Interfaces with single or multi-speed air conditioner or heat
pumps. With multi-speed systems, it operates at the lower
speed most of the time. Only on extremely hot and cold
days does it operate at a higher speed. This staged heating
and cooling eliminates temperature swings, enhances
comfort and optimizes efficiency.
w Improved air filtration in continuous fan mode
w Constant air flow over a wide range of static conditions, even if filters are dirty or registers are closed.
