Product Introduce
DICHENG DSR50G industrial air blowers adopts the advanced technology of Japan,
| Type of technology | Positive displacement blowers |
| Design | Positive pressure |
| Air capacity | 0.61 to 0.95 m³/min |
| Discharge Pressure | 63.7 to 98.0Kpa |
| Medium | Air, Neutral gases |
| Conveying | Oil-free |
| Rotating Speed | 1350rpm |
| Discharge Diameter | 50mm(or customized) |
The main characteristic of our industrial air blowers is small volume, light weight, flow strong, noise small, steadily reliable operation. This industrial air blowers 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. 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.
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 | 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 |
| 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 |
