Product Description

DSR65 Roots Blower ,Wastewater Aeration Blowers

Product Introduce

DSR65 Series Roots Blowers adopts the advanced technology of Japan,
its air capacity is 1.07m3/min - 3.64m3/min,
the pressure is from 9.8Kpa to 58.8Kpa.
The main characteristics includes:small volume, light weight, strong below , 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.
