Passive Pre-Filter Modules: 
Dust and Resinous Sticky Fume / Smoke
  • Who Needs It?

    Customers that have heavy dust loadings, work with resinous materials that produces "sticky smoke", will appreciate this pre-filter section since it will prolong the life of the primary filters inside the SPH800/SPH400 extractors, reducing the maintenance costs.

  • What's Inside?

    The PF801/PF401 modules contain three (PF801) or two (PF401) high-capacity antimicrobial, multilayered, dust filter bags that can capture a significant amount of dust and particulate matter before it reaches the primary

    filters of the SPH800/SPH400 units.

  • Easy Filter Change

    Whether you have a standalone or add-on module filter

    bags are accessed in the same manner. Remove inlet

    cover, quarter turn 4 locking mechanisms and remove

    the section to replace bags. Designed to be clean simple and effective. Dust is contained in the bags to minimize the mess and exposure of personnel to potentially harmful dust.

  • Add-On And Stand-Alone Versions

    The PF801/PF401 passive pre-filters can be used either

    as add-on modules to an SPH800/SPH400 air purifier or

    as standalone mobile units. The standalone modules,

    can be used with virtually any existing filtration system.

    The inlet and discharge collars can accommodate many

    different arrangements to suit the application. Single or

    dual 1”, 1.5”, 2”, 2.5”, 3” or 4” diameter collars are

    available as standard options. Custom diameters are

    available upon request.
