The MARK-25 is our industrial workhorse. Four stages of media, including carbon and HEPA will provide cleaner, healthier air for clients, employees, customers and patrons in any type of application.Superior cigar and cigarette smoke removal can be achieved with the MARK-25 Industrial strength air cleaner. A powerful 2,000 CFM, 3/4 hp motor ensures effective air circulation and capture of gases, odors, smoke, dust as well as residual odors and airborne contaminants. The MARK-25 is an excellent choice for factories, bowling alleys, pool halls, manufacturing plants, marijuana growing facilities, etc.

How does the MARK-25 work?

The MARK-25 Industrial Air Cleaner uses a powerful blower to draw the air from dust laden, smoke-filled areas. As the air is drawn through the high-efficiency filter media, 95% of the tobacco smoke particles are removed on each pass. The clean air that is constantly discharged into the area is refreshing and remarkably free of odors, tobacco smoke and other airborne contaminants. 

4 Filter System Provides Unmatched Air Cleaning Results

  • Stage 1 - Pre-Filter - The 1/2" polyester pre-filter removes large particles such as lint, hair, dust and pollen. The pre filter is important because it helps prolong the life of the HEPA filter in the system. Essentially, the pre- filter is the first line of defense in maintaining your system.
    12 - Polyester pre filters are included with each unit. Pre-filters cannot be washed and must be changed monthly.
  • Stage 2 - Activated Carbon Pad - 1/2" activated carbon pad removes odors by absorbing the odor molecules into the filter. 
    6 - Carbon pads are included with each unit. The Carbon Filters cannot be washed and should be changed at least every 2 months.
  • Stage 3 - HEPA Filter - The HEPA filter removes very small particles, such as smoke from tobacco (including hookah, cigarette, cigar & marijuana smoke), burning wood, oil, rosin, dust mites, spores, mold spores, pollen, spray paint, spray paint dust, ashes, cement dust, auto emissions, textile fibers, fiberglass, hairspray, insecticide dust, copier toner and most viruses, just to name a few. As you can see, the HEPA filter is an extremely important filter. When used and maintained properly, it will dramatically improve your indoor air quality. 
    1 - 12" HEPA Filter is supplied with each MARK-25 Industrial Air Cleaner. For best results, the HEPA filter cannot be washed and should be changed annually.
  • Stage 4 - 36# Carbon V-Bank Filter - The 36 pound Carbon V-Bank Filter in the MARK-25 is an excellent choice when the need to control odors and VOC's associated with chemicals is required - including acids, alcohols, ether, sulfuric acid, sulfur dioxide, etc. Activated Carbon removes odors by absorbing gases & VOC's into the porous carbon granules. Think of carbon as an "odor sponge". It can hold many times its weight in odor molecules. However, once carbon becomes "saturated" it loses its efficiency. Thus, proper maintenance of the carbon filter is required to keep your environment fresh & clean smelling. 
    1 - 36# Carbon V-Bank is included with each unit. The Carbon V-Bank Filter cannot be washed and should be changed annually.

    It is recommended that the Mark 25 Air Cleaner be installed in areas that have 12 - 14 foot ceiling heights or more. The Mark 25 Air Cleaner is equipped with 4 eye bolts installed 16" on center on top of each system for easy installation. The installation hardware also includes: 4 "S" hooks, 4 eye lags and industrial hanging wire. 1 unit recommended for every 10,000 cu. ft.

    The MARK-25 is Available with Optional Ultraviolet Germicidal Lamps!

    UV Bulb for Commercial Air CleanersWhy Optional Ultraviolet Germicidal Lamps in Commercial Air Cleaners?

    It is well known that ultraviolet germicidal lamps can destroy any microorganism that comes in contact with its powerful UV-C rays. As a microbe passes through UV-C, the light penetrates directly into the organism's nucleus disrupting the molecular bonds of it's "DNA". This breakage renders the microbe unable to reproduce and shortly thereafter the organism dies, leaving no offspring. This method is recommended by the Centers for Disease Control for its germicidal effects. The destruction of germs and bacteria by germicidal ultraviolet light is accomplished quickly and effectively. Filters trap particulate, and only when germs are attached to particulate, can the germs be trapped. The use of UV-C along with a highly efficient filtering media provides a truly clean, virus & bacteria free environment.
