Cartridge filters are a type of filter that has a shape or construction similar to a cartridge. They are used to clean the air in ventilation and air conditioning systems in buildings, cars, and other devices. Cartridge filters have several advantages, such as a larger filtration surface and ease of installation and replacement.
These are some of the typical materials used to make cartridge filters:
- Synthetic fibers:
- Many cartridge filters are made of synthetic fibers such as polyester, polypropylene, or polyurethane. These materials are highly effective in retaining microparticles and dust.
- Paper:
- Some cartridge filters use paper materials. Paper filters can be treated with special substances to improve their filtration efficiency.
- Activated carbon:
- Cartridge filters for odor and gas adsorption may contain activated carbon as an additional component.
- Heliofilter:
- Some filters have a heliofilter coating that can block a certain percentage of sunlight and UV radiation.
- NERA filters:
- High Efficiency Particulate Air (HERA) cartridge filters are used to trap the smallest particles and can be constructed with sophisticated components such as fiberglass or specialty fibers.
- Metal nets:
- Some filters may have metal meshes or frames to increase stability and durability.
- Antimicrobial or anti-allergenic coatings:
- Some cartridge filters can be treated with antimicrobial or anti-allergenic agents to improve hygiene and prevent the development of bacteria or fungi.
The filter construction includes a housing and filter cartridges with filter material of the appropriate cleaning class. This is necessary to effectively prevent contamination of the air environment in ventilated rooms and to protect parts of ventilation equipment such as fans, air coolers and air heaters.
It is important to note that the duct filter can be installed regardless of spatial orientation. When installed vertically, the air flow passing through the filter should move from top to bottom.
The use of a channel filter is not allowed in the following cases:
- in systems for transporting gas or vapor-air explosive mixtures from technological installations where explosive substances are heated above their flash point or are under excessive pressure;
- in systems where media with aggressiveness to zinc-coated carbon steels exceeding that of air or containing sticky or fibrous materials are transported;
- in systems that are not regularly cleaned according to the established schedule to prevent the formation of combustible deposits.
The permissible temperature range of the transported air is from -30°C to +70°C.
