Description

DRRF250 Roots Blowers are twin-lobe type roots blowers, adopt the advanced technology of Japan, its air capacity is 61.6m3/min- 120.4m3/min, the pressure is from 9.8Kpa to 98Kpa. The main characteristic of our air blower is small volume, light weight, flow strong, noise small, steadily reliable operation. Feature 1. Air capacity and pressure can be customized 2. Stable air capacity 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 Specification Type of technology - Positive displacement blowers Design - Positive pressure Medium - Air, Neutral gases Conveying - Oil-free Discharge Diameter - 250mm(or customized) Parts Inlet filter silencer Discharge silencer Anchor bolts Baseframe, Safety valve, Check valve, Discharge pressure gauge, Flexible connections Lubricant. Package Fumigation free plywood case Iron case Certificate CE certificate, ISO9001 certificate and SGS certificate. 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 20℃ 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.
