Stadio soffiante a 3 lobi. Adatto a una vasta gamma di applicazioni. Disponibile in 22 grandezze standard (da GM 3S a GM 1080L).
Blower with 3-lobe rotors and two cast-in preinlet channels in the discharge-sided cylinder part to minimize 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.
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. If you have questions about any other materials please contact us.
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.
From top to bottom (vertical)

Overhung drive via narrow v-belt, directly driven via flexible coupling or with gearbox.
AERZEN Positive Displacement Blowers (of the "Roots" type design) have been manufactured since 1868 and today are highly developed standard production machines designed and adapted to find use in a wide variety of applications.
The following are only a few examples of the many applications in which Aerzen Blowers can be used:
