Aerzen Blower

Aerzen Machines Ltd Stand: A13

Introduction:

The Delta Blower Generation 5 is a combination of successful characteristics developed in previous generations merged with new technical innovations that already meet the market requirements of the future.

Advantages: 

• Low noise levels,  operation-friendly & low maintenance design,  mechanical fan,  no absorption material, energy-efficient design

Design

Blower with 3-lobe rotors and two cast-in pre inlet channels in the discharge-sided cylinder part to minimise the sound by pulsation reduction. Housing ribbed and air-cooled. Blower cylinder undivided up to GM 400 L. From GM 430 S the cylinders are horizontally divided. Up to GM 80 L the feet at the blower are bolted on, larger sizes are cast on. Lube oil supply by splash lubrication.

Materials

Housing parts (cylinder, side plates, gear case and housing cover) made of GG-20. Shafts made of C 45 N and rotors made of C 45 N (GM 3 S up to GM 80 L); shafts and rotors are forged in one piece. On size GM 90 S and GM 130 L pistons and shafts are cast of one-piece EN-GJS-500-7 (GGG50). Rotors made of EN-GJS-400-15 (GGG40). (GM 150 S up to GM 1080 L) helical timing gears made of 16 Mn Cr 5E. In case other materials are needed, please ask for details.

Shaft sealings

Conveying chamber seal by 4 piston ring labyrinth seals with oil slingers at each shaft end. On request, 4 radial seal ring-piston ring labyrinth seals are available. Driving shaft seal by radial seal ring. In case of gastight design of the driving shaft 2 radial seal rings are used with an intermediate grease trap.

Direction of flow

From top to bottom (vertical).

 

Position of the driving shaft

Left (viewed onto the driving shaft) alternatively the driving shaft is possible at the right.

 

Drive

Overhung drive via narrow v-belt, directly driven via flexible coupling or with gearbox.
