Self-cleaning pulse air filters
Our filters are self-cleaning to prevent pressure drop. This provides better protection against erosion, fouling and blade corrosion and increases the life of your Gas Turbines. Defitec offers guaranteed customer satisfaction in spite of extremely hostile environmental conditions such as dust, sand or snow storms, low and high temperatures and high-humidity exposure.
Defitec offers a whole air filter range of different medias that achieve M6 – F9 EN779:2012 efficiency classes. For higher HEPA levels of efficiency which seem to becoming more relevant, with Filtration Upgrade programs even in pulse filtration E10 and E12 options EN1822 :2019 are available.
Static air filters
Defitec provides minipleat cassette barrier filters for cleaner and higher compressor efficiency and plant availability.
Our static air filters benefit from very strong and rigid plastic frame and can resist to high burst pressure superior to 5,500Pa without any damage.
Defitec filters range from ISO ePM10 75% (M6) to ISO ePM1 80% (F9) efficiency as per ISO 16890:2016, and from E11 to E12 efficiency as per EN1822:2019. They are tested for efficiency, burst strength, and water repellence.
Metal stainless-steel filter-elements
Defitec can replace industry standard metal stainless-steel filter-elements with industrial gas and liquid filtration processes in the petrochemical, pharmaceutical and chemical-processing industry.
Filter cartridges in sintered stainless-steel fibre or metal powder, wire mesh, wrapped or pleated, bonded or welded assembly according to applications required by the customer.
oil and hydraulic filter elements
Defitec is able to offer a full range of quality alternative filters to existing brands : Argo, Donaldson, Fairey Arlon, Ge, Hilco, Hydac, Indufil, Mahle, Pall Hydraulics, ,Parker, produced using inorganic glass fibre with epoxy coated or stainless wire mesh support layers.
They offer excellent efficiency combined with low pressure drop and collapse pressures up to 210 bar.
All defitec medias have been independently tested at IFTS (France) to ISO 16889 (Multipass) and offer βx=1000 efficiency standard ratings:
β2.5= 1 000 ; β4= 1 000 ; β7= 1 000 ; β12= 1 000 ; β22= 1 000, β38= 1 000
dust collector Filters
Dust and fumes have a negative effect on your business. Industrial processes emit large quantities of air contaminants, in a multitude of varieties and sizes. These can be harmful to your people, causing time off work, breathing problems and inefficiencies. Some are toxic and can cause long term bad health.
Defitec makes a comprehensive range of, value for money pulse filter cartridges to the highest performance specifications and quality standards. By using the most suitable grade of filter paper or spun bonded media, we can make the air safe for people to work in and prevent contamination of products and processes.

dynamic air filters (Cyclone)
A propeller fixed at the entrance provokes a swirling effect to the entering airflow.
The resulted centrifugation concentrates the dust particles close to the inner surface of the spin tube whilst the clean air centre stream flows through a conical device placed at the spin tube end opposite to the propeller. The dirty airflow of particles mix to be eliminated is ejected outside the « Cyclone » by a secondary airflow, called as well scavenged airflow.
The airflow direction between upstream and downstream remains the same.
