Filtration systems, providing greater filtering surface became of the bag filter development. So our company offers the filter elements which in comparison with the filtering sleeves have a greater filtering surface, which in turn provides a significantly higher degree of air purification to 0.2 mg/m3, depending on dust, and several times greater durability of the elements themselves (15 years). While these filter elements have a high resistance to the abrasive dust.

The polluted air through a network of pipelines from the process equipment falls into the pre-filter chamber, where the speed is reduced, and a uniform distribution of dust on the filter elements. Further, the dust-air mixture is directed into the dirty chamber of the filter, passing through which, all the dust remains on the filter elements, clean air into a chamber of pure gas, then use a fan vented outside the filtration system.

Due to the high degree of purification (the concentration at the outlet less 0.2 mg/m3), the air can be returned into the working area, allowing you to save on heating in winter. Regeneration of filter elements are formed by the time or by the value of the differential pressure between the chambers. During regeneration caught on the filter elements of dust crumbles in the bulk container, from where by means of a screw conveyor and rotary valve is unloaded.

Due to the structure of the filter elements for their recovery is enough pressure of compressed air at 4.5-5 bar to 6 bar, required for the regeneration of bag filters, which provides a power efficiency for such filters. The consumption of compressed air required for regeneration is much lower due to the fact that all the dust remains on the surface of the element and does not penetrate into the fabric structure (as in the use of bag filters). In the end, dust is more easily shed from the filter elements.

Scope of application:

  • Aspiration system for collecting dust with a particle size less than 1 micron

Technical specification:

  • particles of size < 0.5 µm capture

  • residual dust content < 0,2 mg/m3

  • ability to return filtered air to the shop with the aspiration

  • a constant level of resistance in the process of operation

  • high filtration surface of one filter element (7 m2)

  • service life of filter element is > 10 years

  • pressure of compressed air for regeneration of the filter elements at the level of 4,5-5 bar

Advantages compared to bag filters

Residual dust content less 0,2 mg/m3

High efficiency dust removal is caused by the special properties of the filter elements and their design. They are made from a layer of sintered polyethylene and a layer of membrane made of Teflon with a pore size of 2-3 µm. These filter elements have a high filtering area (from 0.25 to 7.6 m2) and ensure the capture of particles smaller than 0.5 microns.

The solids content at the exit of the filter at the level of < 0.2 mg/m3 increases profits at the collection target product, it allows you to return the cleaned air back to the shop, saving on electricity (heat)

Stable operation at gas temperature up to 450 °c

Depending on the material of the filler it is possible to manufacture the filter elements employed in filtering gases at temperatures up to 450 °C

Filter element service life up to 15 years

Due to the very high chemical stability, low abrasion of the tool body and coatings with high mechanical strength, service life of the cartridge elements more than 15 years. Filter elements can be washed with water. Due to surface filtration, and is not voluminous, as in a baghouse, cartridge filter elements are easily regenerated and cleaned

Size is 40% smaller

The modularity of the system, high filtration surface (from 0.25 to 7.6 m2) and the construction of the filter elements, easy regeneration significantly reduce the dimensions of cartridge filters. So at one and the same performance for the cleaned gas, the cartridge filter will be 40-50% less to occupy space than the bag filter. A wide variety of installation methods

High fire and explosion safety

Through the use of various modern materials in the manufacture of filter elements is possible their production in antistatic performance, they also do not support combustion. The filter elements are not clogged, which ensures in particular the mechanical integrity of the cartridge
