Bulk Vehicle Blowers

Twin and Tri Lobe Blower

Aerzen Bulk Vehicle Blowers are manufactured in twin and tri lobe design and usable for conveying of air. Intake volume flow approx. 600 up to 2.250 m³/h.

Intake volume flow	:	approx. 600 up to 2.250 m³/h
Size	:	4
Suitable for	:	conveying of air
Pressure operation	:	up to max. 1000 mbar or 1200 mbar peak pressure
Suction operation	:	up to max. -500 mbar

Design with 3 Tri 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 / twin 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.

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.

Special materials :
None available.
