• 4” hose barbed adjustable porting for the intake and exhaust
• Integral final filter with easy access cleaning
• 4-Way pressure/vacuum change over valve
• Designed, built, and supported in the USA
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.
Sound Level
It is recommended the operator monitor the blower while running and listen for resonances (increased levels of noise) that may occur at certain RPM’s and operate the blower at speeds above or below the resonance speeds to reduce excess noise. The noise level of the blower may increase with higher levels of vacuum and RPM. To minimize noise, operate the blower at the minimum speed and vacuum level required to achieve the desired performance results.
