The building blocks for air scrubber system designs.

Chemical Media Modules

We design ProMark modules to hold loose, dry filtration media in such a way that air easily passes through them. Available in steel, refillable, or plastic disposable materials, these modules are building blocks for air-scrubber systems of various designs. We can replace existing modules with equivalent or superior modules based on the size, thickness, and type of media that your application demands. Flat panels are available in almost any size and any metal as well as in disposable honeycombed trays for direct replacement.

The patented PMA25 module is a new design that maximizes media availability and residence time. Its aerodynamic airflow reduces resistance and turbulence. The PMA25 module has twice the media, twice the residence time, with half the drop in pressure associated with standard 18 and 12 modules. See detailed comparison.

  • Dimensions (Nominal): 8″h x 12″w x 24″d (203 x 305 x 610mm)
  • Filter-media bed depth: 2″ (51mm)
  • Number of modules per 2 ft x 2 ft cell: 6
  • Maximum duct velocity: 600 ft/min Airflow: up to 600 ft/min (3.05 m/sec)
  • Construction: mild steel powder‑coated or stainless steel


Refillable: PMA12 and PMA18

Refillable modules meet and exceed industry standard sizes with ease of use and solid steel construction. These are available prefilled with customer-specified filtration media. Construction is standard mild steel with a powder coating and also available in 304 stainless steel. Dimensions (Nominal): PMA12 – 12″h x 24″w x 12″d;  3″ media bed depth;  2 modules per 2’ x 2’ cell PMA18 – 6″h x 24″w x 18″d; 1″ media bed depth; 4 modules per 2’ x 2’ cell

Disposable: PMD12 and PMD18

Disposable modules come in industry-standard sizes with the added convenience of plastic disposability. Disposables come prefilled with customer-specified media. The PMD12 and PMD18 are packaged two per box for easier handling at the installation. Dimensions (Nominal): PMD12 – 12″h x 12″w x 12″d; 3″ media bed depth; 4 modules per 2’ x 2’ cell PMD18 – 6″h x 12″w x 18″d; 1″ media bed depth; 8 modules per 2’ x 2’ cell

Refillable Steel Panels

Refillable steel panels are available in standard and custom sizes and come either filled with filtration media or empty. They are made of mild steel and powder painted for corrosion resistance.
