About BK-3

BK-3 series roots blower, the third generation of BK blower, inherits most of the advantages of BK blower. With rotor curve optimized, the blower is featured of high efficiency and reliableperformance. The blower is cooled by natural air under 80KPA boost pressure, no need for other cooling device. And a little floor space is required by its compact structure.

Features

Optimized lobe curve is adopted for reducing blower’s internal leakage, improving blower’s efficiency and reducing running temperature.

After radius-center distance ratio narrowed and shaft’s diameter enlarged, no deformation and collision will occur under higher load pressure as the blower’s strength is improved.

Unique end-cover structure is adopted for making bearing cavity separated from gas chamber relatively, so there's little impact of inside high temperature rising on bearings.

In order to lower blower's noise, deep groove ball bearing of high precision and low friction factor is adopted. Also due to larger size bearing used for matching enlarged shaft diameter, the bearing’s load capacity is improved and its service life is prolonged.
