Air Filters
The company «Selton» offers a wide range of filters for purification and preparation of air of various designs and classes of purification.
You can buy pocket, panel, sleeve and cylindrical air filters by contacting the contact numbers listed in the Contacts section.
Relevance of installing filters for air purification
Filter elements for air purification are used in almost all applications from domestic air purification systems to industrial air treatment for gas compressor units or pharmaceutical production.
Depending on the installation site and equipment, they can also be used to remove mechanical particles, droplets of moisture or suspended solids.
The use of air filters in industrial equipment protects system components from premature wear or contamination, thereby extending service intervals and reducing the cost of replacing equipment parts. Both the cylindrical air filter and the industrial air filter can handle these tasks with ease.
Filter classification
Air filters can be divided into the following groups according to the cleaning fineness:
- coarse cleaning;
- fine cleaning;
- High efficiency air filters.
Coarse air filters include products designed to trap particles larger than 0.4 microns.
Fine air filters include products designed to retain particles sized 0.4 microns with an efficiency of at least 40%, but not more than 98%.
Ultrafine air filters include products that ensure cleaning from particles and aerosols sized less than 0.4 microns. See more details about ultrafine air filters and order by clicking the link.
Pocket filters
Pocket filters for ventilation are the most common type of filters for ventilation and air conditioning systems.
Pocket filters are designed to remove dust (contaminants) from outdoor and recirculating air in the supply ventilation, air conditioning, air heating systems, and in other air preparation systems.
A pocket filter for ventilation consists of a galvanized or plastic frame and filter material soldered (welded) in the shape of pockets. Optimally aligned design of the pocket filter provides for maximum performance and high dust holding capacity with low airflow resistance. Pocket filters feature longer service life and good ability to retain contaminants, various impurities.
Selton LLC manufactures pocket filters of G3 – F9 cleaning classes according to EN 779 (DSTU 4319).

Panel filters
Panel air filters (frame) are no less popular than the pocket filters. They differ with more compact dimensions and can be installed in equipment or systems of limited dimensions. Compared to pocket filters, these filters have a number of advantages and disadvantages.
The advantages of panel filters are their small sizes and high performance in systems with low air flow. In case of pocket filters used in ventilation systems with low air flow, there is a possibility of pocket ‘folding’ and, as a result, a surge in resistance on the filter itself.
The disadvantages include a smaller cleaning area and, accordingly, a lower dirt holding capacity of the filter in general as compared to a pocket filter of a similar frame size.
Like filters, pocket filters, panel filters for ventilation are made with purification classes from G3 to F9 according to EN 779 (DSTU 4319).

Filter unit
Filter unit consisting of a metal section for mounting pocket filters G4 and doors for sealing and securing filter elements in the frame. Designed for filtering large volumes of air, it is ideal for cleaning external air (air taken from the surrounding environment) and recirculated air in air conditioning systems and supply ventilation in various technological units and systems. The material and dimensions of the unit are tailored to meet individual customer requirements. The unit can be equipped not only with pocket filters, ranging in filtration class from G4 to F9, but also with higher efficiency HEPA filters from H10 to H14 classes
