Roots Blower

Longtech Taiwan Roots Blower

Longtech three lobes Roots Blowers are a new series of Roots type blowers. Roots blowers are positive displacement pumps that are one of the most efficient types of pumps in their performance range. Roots blowers run dry as the oil is contained in the bearing/gearbox housing and sealed from the process air.

The three lobe technology reduces noise by as much 5dBa, this also lowers vibrations and increases the life of the bearings. The Longtech blowers are CNC machined to precision tolerances, promoting air performance and efficiency.

The Longtech blower range can handle from -500mbar to +800mbar with flow rates from 30m3/hr to 21,750m3/hr. The blowers are available as just the blower or as a blower package through to a full blower enclosure. Optional VSDs can be supplied also be provided.
