#04 - Dust & Fume Filters - Centrally Ducted


Centrally Ducted Dust Collectors such as these are ideal for large shops and centrally ducted applications. Most of these solutions are based upon self-cleaning filter cleaning systems to help reduce filter costs. In addition, Water based filtration systems are available for certain explosive and flammable applications

Some important points to consider when purchasing:

  • What is the Total Flow Rate? (Add up all the inlets that will run at once)
  • What is the exact resistance (filter and duct losses) required for the fan to overcome?
  • Do I have enough filter media (Air to cloth ratio) in the collector?
  • Will it stand up to your environment (Eg: is it made from Plastic or Steel?)
  • Filter cleaning: Does the filter cleaning system really work in your application?
  • What will be my filter, maintenance and energy costs per year?
  • Are there any tertiary risks such as fire, explosion, etc, that I need to consider?


    Here are some general design velocities when using "CAPTURE" Hoods:

    Smoke (e.g.Welding):
  • Capture Velocity 100 FPM
  • Transport Velocity 3000 FPM
  • Minimum Face Velocity 2355 FPM

    Dust (e.g. Grinding):
  • Capture Velocity 500 FPM
  • Transport Velocity 4000 FPM
  • Minimum Face Velocity 4000 FPM

    Gas (e.g. V.O.C.'s):
  • Capture Velocity 50 FPM
  • Transport Velocity 2000 FPM
  • Minimum Face Velocity 785 FPM

    (04-07) F1-HWF Wet Collector - Explosive Dusts - Self cleaning filter system built in - 1,000 to 15,000 CFM
    HYDROTRON Water Filter Dust Collectors purify air by a combination of centrifugal force and violent mixing of water and contaminated air. As the air stream passes the fixed baffles, particulate is separated by heavy, turbulent curtain of water created by high velocity air. The centrifugal force caused by the rapid changes in airflow direction forces the dust particles to penetrate the water droplets and become entrapped. Contaminated water is then removed from the airstream by special mist filters. Dust, as sludge, settles to the collector bottom and the water is reused.

    The HYDROTRON is specifically designed for safe collection of potentially explosive and volatile materials and is effective in the capture of fine metal particles. It meets the National Fire Protection Association guidelines for processing and finishing aluminum. Since the Hydrotron also meets OSHA and NFPA regulations for dust removal located inside buildings, it can recirculate in-plant, tempered air to conserve energy.

    (04-08) F1-CF1 Cyclotron (size/flow to suit)
    The CYCLOTRON combines a long tapered cone, a high velocity inlet, and a large internal helix to easily separate from the air stream all moderate size particles, such as saw dust chips and particles from metal grinding. The CYCLOTRON fans are positioned on the clean air side of the cyclone and are direct drive for low maintenance. In addition, the fans have backward inclined blower wheels for high efficiency and low noise operation.

    Optional Safety After Filters ensure that even the smallest particles are captured. Standard filter material for the after-filters is 16-ounce seared, felted polyester, designed to hold large dust particles to the outer edges, thus forming a filter cake which heightens filtering efficiency and facilitates easy removal.

    (04-09) F1-BT Bagtron (size/flow to suit)
    LEV-CO’s Bagtron series of units filter fine to moderate-sized particles and provide on-line filter cleaning for uninterrupted dust collection. Designed for use on dust which is curly, sticky, long fibers, abrasive, forest products, food products (hydroscopic), making these materials difficult to self clean from cartridges. Industries benefiting from this technology include paper products, concrete production, food processing, forest products and aircraft parts manufacturing. Other processes for this equipment include sanding, chipping, planning, bailing, processing, blasting and cutting. The Bagtron is used on fine to medium particulate; heavy loading; wood, metal plastic and composites; particles that present special problems, including wood or metal shavings, hydroscopic dust and paper shreds.
