Product Feature
1. Air flow and pressure can be customized
2. Stable air flow and less pressure variation
3. Clean air not with oil moist
4. Construction simple and easy maintenance
5. Bearing are all lubricated by oil moist
6. Long service life
Description of Performance parameters
The performance parameters table shows the model, outlet diameter, rotate speed, discharge pressure, air capacity and power of motor.
1. The air capacity and pressure in the tables is in standard suction state. The standard suction state is 20ºC temperature, 1.033 kgf/cm2(101.3Kpa) Standard atmospheric pressure and 65% relative humidity.
2. The air capacity and pressure range of some blower models is repeated, to ensure the service life and low noise, should use the larger model.

Roots Rotary Blower Application
| Water Treatment | Aquaculture | Powder and granules
transportation |
| Be used in water treatment plant for water purification and sediment mixing | Be used in a variety of fish pond for oxygen supply and mixing, and also for aquariums and live fish tank | Powder or granules
(such as plastic materials, etc.) can be transported by pressure or vacuum |
| Incinerator | Ballast pump | Sandblast |
| Air combustion and exhaust emissions | Used for chemical liquid unloading and other ballast pumps | Used as air source for blast jet |
| Booster | Compost fermentation | Cereals Transportation |
| Used for high-pressure exhaust to make the gas into tiny molecules | High-pressure air take into the livestock manure tank to increase contact area of livestock manure and air , also apply to sewage treatment | Cereals such as wheat are transported from the rotary pilot valve with air |
| Pipe clearing | Sauna | Plating Bath |
| Used to remove dirt and iron dust during pipeline replacement or overhaul | Used for the sauna to provide air bubbles, mainly used for hospitals, hotels and etc. | Use air to stir the electrolyte to keep the electrolyte circulation, and disperse the attached blister to make plating quickly, spread evenly |
| Produce line drying |
