Oneida Dust Deputy 2.5 Cyclone Separator DIY Version

  • Oneida Dust Deputy 2.5 Cyclone Separator DIY Version AXD-251004

    The Dust Deputy turns your tired old wet ‘n’ dry vacuum machine into an efficient, effective two-stage extraction system, minimising suction loss, reducing filter changes and improving workshop air quality.

    Its cyclone technology works on a wide range of materials. Whether you are a woodworker, a DIYer, a bone or stone carver, or a teenager whose parents are coming home after a weekend away and you need to tidy up in a hurry, the Dust Deputy will speed up your cleanup.  

    Optimized for the more powerful wet/dry vacuums that have become standard over the years, the Dust Deputy 2.5 Cyclone Separator delivers up to double the airflow of smaller cyclones and lid-style separators.

    What's Included:

    • Anti-Static Dust Deputy Cyclone Separator
    • Pre-cut Neoprene Foam Gasket
    • Lid Mounting Hardware

    What Else You'll Need:

    • Wet/Dry Vacuum with a 2.5" Hose Inlet
    • Reinforced, Airtight Dust Container (any shape/size)
    • Vacuum Connection Hose (2.5" recommended)

    Cyclone Technology

    The principle behind cyclone separation is straightforward. The air containing particles enters the cyclone chamber from the side which causes it to spin rapidly around inside the chamber. The dust particles are thrown against the inside wall of the chamber, where they drop out of the airflow and fall into the collection chamber beneath. A low-pressure zone develops in the centre of the cyclone through which the clean air is able to exit. Cyclone separation typically removes 99% of particles, leaving the smallest 1% to be captured by filtration.

    Universal Compatibility

    Any wet ‘n’ dry vacuum that is rated at 50cfm or greater can be used with the Dust Deputy.

    Reduce filter changes

    There are no filters inside the Dust Deputy – the dust is removed solely through cyclonic action. Only 1% of the material makes it through the cyclone to be caught in your vacuum’s filter, massively reducing the number of times you need to clean it out.

    Reduce Suction Loss

    A filter caked with dust will increase resistance to the airflow and can significantly reduce suction. The Dust Deputy removes the dust before it even gets to the vacuum. When your filter is not getting blocked up, the vacuum will continue to run at full air velocity for much longer.

    Easy Emptying

    The Dust Deputy 2.5 DIY kit can be mounted to a wide range of strong collection containers, so emptying the dust is as easy as removing the container’s lid and dumping its contents.
