General Blower Operation

The NVE BLOWERS are severe-duty vacuum pumps, designed to be used in liquid waste pumping systems where extended operation is desired. The blower incorporates a ballast air cooling system to provide superior cooling, allowing for extended operation. Air enters the intake under vacuum or at atmospheric pressure. As the rotors rotate, a fixed volume of air is moved along the cylinder wall towards the exhaust where the pressure and temperature of the volume of air increases. If the intake air is below atmospheric pressure, cooling air will be drawn in when the rotor tip passes the ballast port. The airflow capacity of the machine (in ACFM) is nearly proportional to the speed of the machine and is nearly constant with changes in inlet or outlet pressures.

Air Flow Control

The airflow rate on the blower can be adjusted by changing the speed of the blower. This can be accomplished by changing the PTO ratio, gearbox ratio, belt drive pulley diameters or engine speed.
