These are positive displacement twin lobe rotary blowers and are available from capacity of 30 CMH to 10000 CMH and pressure upto 10000 mmwg with single stage operation. Based on the pressure, the castings are made to facilitate water or air cooling arrangement.

Roots Blowers is a positive displacement, constant volume machine which operates against varying pressure. The Two "8" shaped impellers (involute design) which are mounted on parallel shafts, rotate in opposite direction and with every movement of the impeller across the compressor inlet, a definite volume of air is trapped and carried across the casing to the compressor outlet where this air is discharged. With a constant speed operation, the displaced volume is essentially the same at a constant pressure, temperature or barometric pressure. Increasing the speed of the compressor/blowers against a constant pressure increases the volume of air delivery. The timing gears fitted in a compressor control the relative position of the impellers to one another and maintain small but definite clearances. This allows operation without the need for lubrication inside the casing.

We specialized in manufacturing precision engineered water ring vacuum pump with latest technology and qualitative materials. Our range is attributed with low power consumption, durability, long service life, low noise and high performance.

We manufacture 12 different models of Waterring Vacuum Pump ranging from QWV-1 to QWV- 12. The smallest Vacuum Pump is having full open suction capacity of 50 M3/ hr and is being driven with 3 HP Electric Motor, while the biggest model of Vacuum pump is having full open suction capacity of 2025 m3/hr and is being driven with 90 HP Electric Motor.

These Vacuum Pumps can also be used for compressor duty "with slight modification in installation. The Watering Compressors can develop pressure up to 1.5 Kg/cm² gauge.

• Special Features:

• Simple & Trouble free operation
• Moist air, aggressive gases, vapours & dust laden gases can be handled
• No metallic contact inside machine, less wear & tear,
• Oil free exhaust
• No lubrication
• No contamination of medium passing through
• Compression takes place with small temperature rise.
• Compact unit due to direct drive
• Simple construction
• Easy Maintenance
• Interchangeability of mechanical seal without any change

"SPRINKLER”: Our Bottle type tower is fitted with rotating type of Sprinkler, The Sprinkler head is made of Alluminium alloy to avoid corrosion. It rotates at 5 to 7 RPM by the reaction force of circulating water, which is discharged at low pressure out of holes of PVC Pipes and evenly distributed over PVC fills to achive maximum wetted surface area.

“OPTIONAL”: Also our cooling tower is supplied with P.V.C. Nozzles fitted on M. S, galvanised distribution pipes.

• Fills:

Our honeycombed PVC fills are high performance, heavy duty, low weight, excellent resistance to corrosion: These offer a striking balance between maximum heat transfer surface area vis-a-vis minimum restriction to air flow. Thus providing more cooling at lower power consumption of the fan motor. They are arranged in a manner to facilitate easy replacement.
