Media Solutions.

Our patented, spherical, porous pellets are comprised of different chemical compounds such as activated alumina, sodium permanganate, activated carbon, and potassium permanganate. We remove gaseous pollutants from the air through a unique chemical process known as chemisorption.

During chemisorption, the media converts harmful gases from the air into harmless materials that are trapped inside the pellet. This process is instantaneous and irreversible.


Our convenient modules allow a user friendly way of solving odour and protecting valuable equipment from corrosion issues with a compact refillable module.

Deep Bed Scrubber (DBS).

Corrosive gaseous contaminants of your compressor can inhibit air flow, impede heat dissipation, cause vibration and decrease energy efficiency.

The Purafil Deep Bed Scrubber is a highly effective, bulk media scrubber designed for controlled environments with medium-to-high contaminant gas levels. It is ideal for pulp and paper mills, refineries, steel mills, smelters, chemical plants, petrochemical plants, and other hostile environments.

The DBS remedies the gases’ corrosive effects and meets stringent air quality standards set by the International Society of Automation (ISA). It also functions, if needed, as a shelter-in-place application to protect employees.

Manhole Scrubber (MOLE).

The MOLE Manhole Scrubber is a passive odor control system for street-level sewer manholes. It is designed to eliminate noxious sewer odors on busy streets filled with pedestrians. Odors enter the MOLE through the bottom of the unit and flow upwards through two vertically stacked disposable sacks of Odormix media.

Parallel Bed Scrubber (PBS).

The Purafil Parallel Bed Scrubber is a large, bulk media scrubber that removes high concentrations of target gases with very high horizontal air flow in municipal and industrial markets. This equipment is indicated for different applications such as screening rooms, headworks, large pump stations, refineries, and petrochemical plants. It is also used to polish the biofilter discharge air.


Reduce harmful corrosion in important control cabinets by using ProtectorVent.

Purafil’s “Understanding RoHS” publication explains this problem in depth – available from us by request.

Control cabinets need more than just a sealed door either because it’s impossible to seal the cabinet 100% or heat build up requires venting.

Protectorvent TM overcomes these problems by positively pressurizing the cabinet and removing the gaseous contamination before it enters the cabinet.


Features & Benefits

Simple mounting brackets and small profile fan make it a breeze to fit to existing cabinets at a low cost, various configurations are available.

Protectorvent TM offers three stage filtration comprising G4 double coalescor filter to remove moisture and dust particles, 2.5l  Purafil media selected to remove the particular gaseous contamination, and a F6 fine filter to remove small particles and dust. ProtectorVents are available as Corrosion protection only ( relatively small airflows concentrating in positive pressure only ), Corrosion protection and cooling air.

Protectorvent TM is simple to service, one minute changeover time for the coalescor pre-filter pads, the fine filter is removed when accessing the gas phase media.

Laboratory Services.

Purafil takes pride in their state-of-the-art laboratory that assists customers in classifying the level of air quality in each individual environment. Each year, over twenty thousand analyses are generated in twelve different languages. We also offer on-site assessments upon request, please contact us for assistance.

Coupon Analysis.

Corrosion Classification Coupons determine whether or not your environment is safe for electronics. As part of Purafil’s assessment service, the laboratory analyzes coupons and issues a comprehensive report detailing the environment’s ISA Classification, the classes of gases present and concentration levels, and humidity effects.

Passive monitoring involves installation of a one-time use coupon that accumulates corrosion over a 30-day time period.

The CCC or Corrosion Classification Coupon reliably determines the type and thickness of corrosion build-up on the surface of each CCC.

Coupon analysis is a service provided to customers as a resource for information on their environment.

Purafil OnGuard System.

Reactivity monitoring is an accurate and reliable method of evaluating the quality of makeup and recirculation air in a controlled environment. Active monitoring involves constant feedback of data measuring the type and level of corrosion, temperature and humidity.

The Purafil OnGuard 4000 measures the overall reactivity level of air contaminants, temperature, and humidity in a controlled environment.

Wall installation takes only minutes and data is accessible anytime, anywhere.
