Types of Blowers

Roots Blower for Vacuum – Longtech three lobes Roots Blower are new series of Roots type blowers. They manufacture precise rotors by using CNC machines. Getting a perfect gap to promote air performance, lower vibrations and noises results a significant improvement compared to traditional Roots Blower of two lobes. Traditional Roots Blower lubricate bearings and gears with grease and oil but Longtech’s is designed to add oil only. It is very convenient to maintain and oil has a better lubricating effect than grease.

Submersible Root Blower – Compact. Much quieter when submerged, without the need for added soundproofing. Strict management of quality standards. For convenience, the motor and blower’s body are connected as one to avoid conveyor installation. Both motor and the blower are entirely sealed with an o-ring to ensure waterproofing and a special outer case can easily be removed in case of overheating. Technical customization (size, pressure, design, pump accessories.

Root Blower – Strict management of quality standards. Technical customization (size, pressure, design, pump accessories). Assembled using state-of-the-art CNC machinery enabling precise measurements and grinding needed for more efficient pumping. Fewer vibrations transmitted through the lobe, for longer-lasting shafts, gears and bearings. Three-lobe design controls any backflow pressure towards rotor. Oil and dust-free outlet. Lubricated with high grade oil, proven to be a much better alternative to grease. Significant improvement in air performance ratios: wider air, pressure and vacuum range, more stable flow, fewer pressure variations. Much quieter: the new design can effectively reduce noise by approximately 5 dB. Lower energy consumption. All our products can be used for OEM.

Vertical Root Blower -There is a vertical motor installed on Vertical Root Blower. Discharge and suction silencer install both sides of the Vertical Root Blower.
