Wet type dust collection is required for the safe collection of combustible metal dust. Wet Type Dust Collection has also been used effectively in many other difficult applications in place of cartridge collectors.

Unique Scrub Design

Water is continuously agitated by the suction of the air through the machine. There are no nozzles, piping or water pumps to clean, repair or replace. The consumption of water is negligible. Only normal evaporation occurs and the water loss is replenished automatically. Collected sludge is easily removed from the sloping tank via the tank access doors, or through the use of an optional automatic sludge removal equipment.

The unique scrub design is completed in a five step process consisting of :

  1. Striking the turbulent water surface in the water tank section of the machine
  2. Passing through a vertical water curtain
  3. Scrubbed through a water cascade on cone walls.
  4. Passing through a horizontal water curtain
  5. Buffeted through the moisture separator section before the fan entry and exhaust out of the machine.

Benefits of Wet Type Dust Collection

The closed loop tank water is used as the collection medium. There are no pulsing systems, compressed air, cartridge media, or bag filters to clean or replace.

Combustible dusts are immediately rendered inert upon being captured and pulled down into the water washing scrub below the work deck.

Processes like mixing and weighing operations involving food or other soluble material are ideal for the Uni-Wash DDB as well.
Regardless of your process, users always enjoy the highest capture velocity in the industry to keep process dust pulled down and away from the breathing zone.

Uni-Wash DDB model wet type down draft tables make setting up a new cell immediate. Installation is simple by easily connecting your power supply and plumbing connections. There is no expensive duct work connections that would significantly add to the cost of the project.
