2. Extremely low noise levels
An outstanding feature of the CB is its unusually Quiet operation. Fan noise is often a problem with mechanical equipment --- not so with Cleaver-Brooks. the exclusive CB caseless fan design draws combustion air into the large plenum chamber of the front head, which confines and deadens fan and air noise. At peak loads, the CB more than meets the low sound levels required for schools,hospitals and institutions. Air inlet is accoustically lined.
SOUND PRESSURE LEVEL SUMMARY
