5.1 Introduction. Fans and blowers provide air for ventilation and industrial process requirements. Fans. generate a pressure to move air (or gases) against a resistance caused by ducts, dampers, or other components in a fan system. The fan rotor receives energy from a rotating shaft. and transmits it to the air.
Blowby gases build up in the crankcase. Before pollution controls, blowby was vented to the outside air with a breather cap, with is simply an open cap with an oil/vapor separator screen. Once of the very first pollution control systems was positive crankcase ventilation, or PCV. With this system, the crancase is SEALED.
