Description:

LBSR-series are standard 3-lobe roots blower , its structure is very compact and have higher running reliability and long life, the inlet sizes are from 1.5" to 14". The tri-lobe roots blower can run under the pressure of 80Kpa without cooling water, and the biggest capacity can be 260 m3/min. Our company has also developed LBSRH water-cooling series blower for the pressure between 80Kpa and 100Kpa. So the biggest pressure of two-stage can be 200Kpa. LBSREH-series are also developed for the biggest pressure can be -500mmHg.

Wide range for air volume, pressure and vacuum
Stable air flow and less pressure variation
Clean air and without oil dirt and/or particles
Construction simple and easy to maintain
Bearings are all lubricated with oil
Lower energy consumption.
Lower noise
Longer bearing life
Strict management of quality standards
Our three-lobe design controls backflow pressure towards rotor so as to reduce energy consumption.
Our new design can effectively reduce noise by approximately 5 dB.
Fewer vibrations transmitted through the lobe increases bearing life by approximately 20%. Conventional blowers generate pressure pulses and vibrations which will diminish power and shorten the life of every bearing, gear and other drive train components.

Applications:

Pneumatic conveying
Waste water treatment plants
Electroplating tanks
Printing
Activated sludge systems.
Vacuum handling systems.
Drying systems.
Absorption transporter (for high standards of hygiene)
Filters.
Hospitals and dentistry

Competitive advantage

All our tri-lobe roots blower are built and checked annually following the strictest adhesion to ISO 9001 and CE quality standards, involving the use of our highly precise and regularly maintained CNC machinery. Scrupulous attention is paid to every detail, in a specialized field where technical errors should be kept to a bare minimum.
