ROTARY LOBE BLOWERS FOR INSTALLATION IN TANKERS AND SILO TRUCKS Aerzen bulk vehicle blowers have been developed for installation in tankers and silo trucks with extended pressure differentials of up to 1.2 bar. Conveyance in two directions possible using either horizontal or vertical flow. Proven technology, oil-free. DESIGN WITH 3-LOBE ROTORS Cylinder with cast-in pre-inlet channels at discharge side to minimize the sound by pulsation reduction. Therefore only vertical installation position is possible. Speed range between 1450 up to 4800 1/min. Oil splash lubrication with oil sight glasses on both sides. SHAFT SEALINGS Conveying chamber by the carbon ring labyrinth seal proven over decades in connection with the neutral chambers open to the atmosphere. Driving shaft with radial seal ring. DIRECTION OF FLOW Vertical, from top to bottom DESIGN WITH TWO-LOBE ROTORS The conveying chamber is completely separated from the oil sumps by a space open to atmosphere. The machine can be positioned upright, suspended from the top, and suspended from the left or right. They are also available with an integrated gearbox with a speed set-up ratio of i=2,1. The operating speed range is 1350 to 3200 1/min. The drive side is grease lubricated, while the gear side is splash oil lubricated. Gear driven models feature splash oil lubrication on both sides. Oil level check by means of dipstick.
