Room Filtration (HVAC) HVAC filters are used to remove dust or particles from air stream.
HVAC filters are used for low levels of dust 2 mg/m3, typically in the air conditioning and ventilation industry. The open fibre mats has volumes greater than 90%. The particles are retained within the interior of filter media. They do not require cleaning. Once scattered the mats are discarded. Typical face velocity for those filters are 0,1 - 3 m/s. Typical area of use is HVAC - heating ventilating and air conditioning system for clean the air in the room.
Air Filters are Used for a Wide Variety of Purposes :
Atmospheric air or reticulated air filtration applications and are particularly suited for ventilation of offices, computer rooms, factories and public and business buildings, hospitals, schools to ensure the good state of health of people
For cleaning the indoor air for the needs of production processes , paint spray plants, electronic, optical, phrmaceutical and food industry where is request of clean air
For cleaning the outdoor contaminated air of nuclear station, laboratory when is the request for cleaned air, because are dangerous for health and life of people.
In order to comply with environmental, health and safety regulation, each air installation may require and individual solution.
Classes of Filtration :
Level
EU2 - G2
Prefilter used with the larger dust concentration in the ventilation systems with limited required efficiency – like electrical cabinets and larger equipment
EU3 - G3
EU4 - G4
Generally used filters for the HVAC and as prefilter for the meltblown media. Also used as a protection on heat exchangers at HVAC.
EU5 - F5
The first degree of the fine particle filtration and as final filter in the paint booths, restaurants, shopping malls. Used also as a prefilter for the higher classes in the car industry, hospitals…
EU6 - F6
Finer degree of filtration in the electrical and other demanding industries, partly also filtration for laboratories and hospitals.
EU7 - EU9
F7 - F9
Finer degree of filtration in the HVAC systems with very high degree of air claenng used in the food industry, production of medicines and demanding industrial products, clean rooms…
Kofil Filter Media
Kofil filter media is produced from the synthetic materials which are resistant to fracture.
Progressive structure makes filter media more efficient and can accept more dust per suface.
Resistant to moisture up to 100% relative moisture
Ecological friendly production
Avability to supply different shapes or sizes besides the standard rolls
Kofil Pocket Filters
Progresive three layer material has high efficiency and high dust intake
Welded seams does not allow the migration of dust outside the filter media
Shape of the pocket is suitable for the easiest flow of air
Non rusting frame
Resistant to temperature up to + 80 o C
Lower energy consumptions and TCO (total cost of ownership) due to the lower middle differential pressures and dust intake on the whole filter surface
Kofil Cassette Filters
Progresive three layer material has high efficiency and high dust intake
Homogenic dispersion of the material due to the dimensions of the pleats
High surface area due to the numbe of pleats
High degree of stability guarantees the problem free operation
Resistant to moisture up to 100% relative moisture
