TB Low-pressure Centrifugal Blower

The TB-type medium-pressure centrifugal blower belongs to the radial flow centrifugal fan category, where the gas handling process is completed within the same radial plane. Widely used in industrial ventilation equipment, its core feature is generating centrifugal force through impeller rotation to achieve gas suction, compression, and discharge. When the impeller rotates at high speed, gas is drawn in from the central air inlet under centrifugal force, compressed, and then discharged along the volute casing. Optimized impeller and flow channel design minimizes energy loss, with air volume output efficiency reaching approximately 90%. Equipped with noise reduction technology, high-temperature resistant bearings, and a heat dissipation structure, it supports continuous operation.

This blower is suitable for:
· Dust extraction in machinery such as laser cutting machines, laser engraving machines, laser marking machines, and woodworking dust collectors;
· Ventilation and air exchange in locations including factories, mines, tunnels, and laboratories;
· Air cooling support for boilers and air conditioning systems.
