Precision engineered brushed stainless steel units.
High performance continuous run brushless motors.
Mounted on castors for mobility.


  • Automatic electronic flow control - maintains a constant extraction rate even as the filter blocks
  • Speed control (adjustable airflow)
  • VariColour filter blocked warning system
  • Low capital and running costs
  • Quick change patented Labyrinth pre-filter delivers longer filter life
  • Submicronic (HEPA Filter) filtration removes 99.997% of particles down to 0.3 microns
  • Activated Carbon Filters removes harmful gas
  • Simple to install and quiet in operation
  • Easy to relocate and precision made from stainless steel
  • Machine Interfacing (Optional)
  • Start/Stop Control: Extraction unit starts/stops when a connected piece of equipment is switched ON/OFF
  • Filter Blocked Warning: A signal is sent to a connected piece of equipment to trigger an alert or to shut it down
  • Remote ON/OFF Switch: 5M cable & switch


Visual and Audible Filter Blocked Warning
Alerts the operator when a filter starts to block so that a replacement filter can be acquired and downtime can be avoided.
