3. Product description:
Working theory: There are two HDSR series roots blower in series. Air goes into
first roots blower to increase air pressure, then through the cooler to reduce temperature,
and going through the second roots blower to increase air pressure further, then discharged
through the pipeline. The two roots blowers are driven by one motor through vbelts or one
double shaft motor.
Usage: ceramics, paper making, electric power, chemical, aquaculture, sewage treatment,
food processing, etc.
Conveying medium: clean air and litmusless gas, not flammable, explosive, toxic and
