A Scrub Above

The large diameter, patented scrub cone assembly works above the water line.  This orifice/impingement design never clogs or loses airflow as with submerged internal venturi designs which gum-up and impede flow over time. There are no pumps or spray nozzles to clog or fail with the Uni-Wash design.

Low-Cost Operation

Using water as a filtration medium has its advantages. Collected dust resides as a sludge in the bottom of the sump for easy removal or can simply be drained away. There are no disposable filters to replace saving money and air borne contamination hazard. Our scrub design also leads to a lower static pressure requirement in the machine, which means less horsepower is required. This lowers the cost of the machine and saves energy over the life of the machine.


High Efficiency Fan Assemblies

Scrolled fans substantially increase efficiency by reducing pressure needed to operate at a given CFM. We combine this with direct drive high efficiency motors.  The result is lower operating costs over the lifetime of the equipment.

ProVent, A Name You Can Trust

The Uni-Wash wet dust collector has been continuously manufactured for over 60 years and continues to be the leading technology for capturing dust without the added cost of cloth filter media. Initially designed for the safe collection of combustible metal dusts, manufacturers have utilized this technology in many other difficult applications with success in more recent years.

Crane slot can be added to ceiling panels to allow a crane to place heavy objects on the deck surface.

Ergonomics are important and adding a footrest to your bench will add to employees comfort while either sitting or standing.



Adding a silencer will decrease the noise emitted via the exhaust air 7-9 decibels



A variety of work surfaces configurations are available.  A Fibergrate surface is standard, however any of the below surfaces are available.

  • Steel
  • Stainless Steel
  • Rubber Matt Over Grating
  • Tool Screen Under Grating

 



A compressed air manifold can be mounted on the dust collector for the convenient use of air tools.

 



A removeable center partition can be helpful dividing the work bench into two separate work stations.
