1 BK Type Three Lobes Roots Blower
Roots blower is a cubage blower, and it discharges a fixed amount of air in proportion to its rotation speed.
Every rotation, there is two lobes to finish three times absorbing and discharging air. Compared with two lobes
blower, it is of less air pulses, smaller load change, higher strength, lower noise and vibration.
Two parallel shafts have three lobes each, the lobes keep small clearance with each other and housing
inside. Every lobes rotation, a certain air will be absorbed at inlet and transferred from the housing inside
surface to blower's discharge port.
Two shafts will be turned by the timimg gears, no any touching between lobes, so it can be turned at high
speed without any lubrication inside. It has the following characteristics: Simply configuration; running
smoothly; good performance stabilization. It has been widely applied in various industries.

3 Boundry dimension of BK9020
Standard accessory include: inlet and outlet silencer, pressure gage, base-frame, blower's pulley, motor's
pulley, belt, belt guard, relief valve, check valve.
4 Main body of BK9020
The advantages of BK9020's main body:
(1) Low noise, energy consumption, smooth operstion and easy installation.
(2) Resistanting load change, stablity ari volume, and with the air chamber, the air flow is stable.
(3) Excellent material, reasonable structure and performed excellently.
5 Other accessaries
(1) YUSV Type unloaded start valve
(2) Multi-function BDFZ-L Type Enclosure
This valve is mainly used in the pipeline for blower, compressor and screw type blower. When blower start,
the air will flow through the valve, and the blower will working without load, after a while, the valve will close
because the pressure difference in the pipeline and out, so it realize start without load for the blower, and
can impacting the equipment and motor.
