Traditional cabs lack a positive pressure boosting system, which makes it easy for outside dust to enter. Existing solutions have large fans and poor filter performance, which cannot effectively filter dust and odors from the air.

Method used

A special fresh air system for the cabs of agricultural and engineering machinery was designed. It adopts a combination of a booster centrifugal fan and a filter element. The filter element filters dust and odors in the air, and the booster centrifugal fan delivers the filtered air into the cab to maintain positive pressure.

Benefits of technology

It effectively prevents dust from entering the cab, keeps the cab clean, and adapts to different environmental needs through replaceable filters to ensure air quality.
