Product Description

The Most Versatile, Durable and Economical Method of At-source Air Pollution Capture

The use of self-supporting joints, flexible hoses and smooth steel tubing make the arms easy to work with and keep it near the source of the air contaminants. So contaminants are removed right at their source. 

This unique design has become an industrial standard for air pollution control.

Fume arm tubes are fabricated steel with cast aluminum joints which include friction disc and are fully adjustable to the workers desired tension. The arms include a handle which completely encircles the hood in order to facilitate easy re-positioning from all sides.

Analyzing the Benefits of its External Support System

External Support System

Its External Joint System has:

  • Free and smooth airflow
  • Low noise level
  • Lower static pressure
  • Quick and simple cleaning
  • Minimal dust build up
  • No contact with interior for adjustment
  • No need to stop the airflow to adjust
Internal Support System

An Internal Support Mechanism has:

  • Reduced airflow due to higher internal resistance
  • Higher noise level
  • Complicated to to clean
  • Dust builds up on internal mechanisms
  • Replace whole hose if broken
  • Contact with dusts to adjust friction and arm balance
