Description for Aerzen Bulk Vehicle Positive Displacement Blower

Rotary lobe blowers for installation in tankers and silo trucksAerzen 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 rotorsCylinder 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 bottomDesign with two-lobe rotorsThe 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.Shaft sealings The conveying chamber is sealed by means of four piston rings in combination with oil slingers adjacent to the vent space. The drive shaft is sealed by a seal ring. Gear driven models are sealed by a radial seal ring. Direction of flow Both directions possible in horizontal or vertcial flow. Drive Via direct coupling or narrow v-belt drive.
