The B series is a family of PD blower packages from 2 HP to 75 HP with pressures to 15 PSI. This design features a heavy duty base plate which provides a rigid mounting platform for the blower, motor and drive. Generally they are supplied with an intake filter, relief valve, and gauge (pressure or vacuum).
For each model, proper blower selection is made by carefully considering bearing life, % of max. pressure, speed, temperature rise, and noise level. Motor nameplate HP is not exceeded even at relief valve settings. This leaves a 15% service factor for extra safety.
All inlet and discharge losses of the filter, silencers and check valves are factored in the performance calculations. Belt drives are designed for maximum belt life and minimum bearing load, with a service factor of 150 to 200 % used.
