Product Details

DSR100 China Rotary Type Positive Displacement Blower,Roots Blower

Product Introduce

DICHENG DSR100 Series Roots Blowers adopts the advanced technology of Japan,
its air capacity is 3.28m3/min - 9.07m3/min,
the pressure is from 9.8Kpa to 58.8Kpa.
The main characteristic of our air blower is small volume, light weight, flow strong, noise small, steadily reliable operation.
This air blower is mainly applied to such trades as water treatment, air transport, mine, vacuum packaging, aquaculture and etc. Our products export to Southeast Asia, Europe, North and South America and etc.

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 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	Car wash dry	Smoke exhaust
Quickly remove the water or oil on the cleaned items	Dry the car after washing	Exhaust smoke quickly to reduce pollution
Stripping from mold	Air cushion of Cut off machine	Dry air knife
Easy to remove the finished product after stamping	Increase buoyancy, easy to move	Use the blower to blow off the tiny dust and water droplets on the circuit board
Feed paper/cloth	Washing machine blow dry	Gas /heavy fuel injection
Collect plastic, cloth, paper and other scrap generated after trimming	Dried bottles after washing, suitable for food industry	Provide high pressure (2000 mmAq) and sufficient air volume
