Twin Lobe Roots Blowers & Exhausters

Twin Lobe Roots Blowers & Exhausters are available in 14 air-cooled and 7 water-cooled models. These cover a range of capacities from 20 m³/hr to 14000 m³/hr and pressures up to 1 kg/cm². The smaller machines are available either from stock or delivered within a short delivery period. Bigger machines are manufactured against specific orders.

Design & Construction Features:

Casing:
Sturdy, Detachable feet allow choice of either vertical or horizontal flow. Main bores fine-bored inside. Outer ribs offers strength and air cooling efficiency.

Casing Cover (Main Cover):
Fine bores with rib support provide rigidity and dimensional stability for accurate centre distance.

Rotors:

(a) Involute profile of lobes ensures uniform clearance in all positions of rotors.
(b) Rotors dynamically balanced as per IS0 1940 (1973E) 1 - 1986. This ensures vibration free running.

Timing Gears:
Gear Pair: Helical design with ground profile and DIN class 5 accuracy. Uniform backlash. This ensures smooth, noiseless and accurate torque transmission.

Fitment of Gears:
(i) Through Tensioning Elements: These elements finished to 10 µ accuracy from special steel. Enable accurate & quick coupling and detachment of gears.

(ii) Through Taper Seat: With the help of Oil Injection System where the pump generates pressure up to 3000 kg/cm2 This method achieves shrink fitment suitable for optimum torque transmission, maintaining run out accuracy 10 µ.

Bearings:
Double Row Angular contact Ball Bearing, Spherical Taper Roller Bearing and Deep Groove Ball Bearings of standard quality. Make and with special clearance ensure that even at over pressure condition the machine runs smoothly without seizure.

The bearing is fixed on tapered withdrawal sleeve, which is having ground finish. This is fitted with the help of specially designed hydraulic nut @ 400 bar pressure; to ensure exact matching of tapers and hence correct fitment.
