Pocket bag air filters can be made of synthetic pocket bag filter material or pocket synthetic fiber media blended with active carton, as well as the fiber glass pocket bag filter materials with various filter efficiency, mainly from F5~F9 (CRAA 430) or EU5~EU9 (EN779) or MERV9~MERV15 (ASHRAE). The pocket bag filters often installed in HVAC systems, so also called HVAC pocket bag air filter, which is designed for industrial and commercial applications as well as for residential use to boost indoor air quality. Sometimes, the pocket bag air can be used for the first stage of the HVAC systems, but mostly will used as a secondary or final filter that behind a pleated primary filter. The pocket bag filter material was adopted the nonwoven filter material with the relevant filter efficiency, for improve the dust loading and reduce the air resistance, the filter pockets will be divided into several small spaces, all the synthetic material will sealed with heat welding and the fiber glass will be sewn by sewing thread but the seam will be sealed with thermoplastic so as to guarantee the filter efficiency at the right requested data.

Especial the break through on TPE diaphragm technology, filter presses from Zonel with the properties of endurable, stable, universalizable and widely used in various industries. Variable filter chamber technology is widely applied on solid-liquid separation in many industries such as chemical, pharmacy, mining, and so on which help to reduce the water content of the filter cake and extremely improved the production efficiency for our clients.
Besides the S.S. filter houses, Zonel Filtech also provide various replacement filter cartridges for liquid filtration, the micron size, materials, product size, connections of the liquid filter cartridges all can be customized according to different usages. The micron rated liquid filter cartridge from Zonel Filtech mainly include PP melt blown filter cartridge series (spun bonded / thermal bonded filter cartridge); the string wound filter cartridge series (include PP string wound filter cartridge, bleached cotton string wound filter cartridge, fiber glass string wound filter cartridge); the micro pleated filter cartridge series; big flow filter cartridge series. The liquid filter cartridges from Zonel Filtech mainly used for pre-filtration of RO, food & beverage filtration, chemicals filtration, pharmaceutical material purification, organic solvent filtration, etc. Any liquid filtration cartridges needed, welcome to contact Zonel Filtech!
Zonel Filtech accumulated abundant experiences on industrial filtrations, such as Mining industries include ore dressing and tailing processing; Fine chemical industries include the chemical solution filtration and the waste water treatment; Municipal sewage treatment/ slurry dewatering; Ferrous and non-ferrous metallurgy waste water treatment; electrolysis metal production, etc; Food and pharmaceutical industries(such as the filter fabric for sugar indutries, etc); Building materials and ceramic industries; Dying industries, etc. All of these industries will equip the filter machines such as filter presses, belt filters, disc and pan filters, centrifuge filters, drum filters, etc. According to the requirements combined with the properties of the material which need to be filtered, Zonel Filtech developed various kinds of filter fabrics to meet our clientâ??s requirements, mainly have 4 series, i.e.
Zonel Filtech provide replacement filter belt for various filter machines, such as horizontal vacuum belt filters (offer vacuum filter belts), belt filter press (offer press filter belt), HVPF belt filters (tower belt filter), drum filters, paper or nonwoven forming machine, etc. The filter belt can be produced with woven filter fabric belt and nonwoven needle felt filter belt, mainly applicated for paper or nonwoven forming (forming mesh belt), juice squeezing (juice squeezing belt), as well as the general sludge dewatering, such as the municipal sewage treatment, coaling washing slurry dewatering, ceramic sludge treatment, red mud dehydration from the alumina industry, potash fertilizer production, phosphoric acid production, desulphurization gypsum dewatering, etc. The woven filter belt (filter cloth belt, filter mesh belt) from Zonel Filtech adopted the optimized PET/ PP/ PA monofilament, multifilament, as well as the spun yarn then combined with various weaving pattern and sound finish treatment (heat setting and calendaring) so as to meet the various filtration requirements for different applications and make them always keep the stable and good filtration performance. The nonwoven filter belt from Zonel Filtech adopted the industrial reinforced scrim and multi-sized fiber composited, after needle punching and heat setting, glazing treatment with the properties of stable size, high filtrate output and good filter efficiency.
Aramid/Nomex/Kavlar Air Slide Fabrics General introduction of aramid air slide fabric: Aramid air slide fabric also called Nomex air slide fabric and Kevlar air slide fabric in the market due to the raw material from the different suppliers. According to the different working circumstance, the aramid materials from Zonel Filtech were adopted the aramid 1313 (similar to Nomex) and aramid 1414 (similar to Kevlar) according to the certain working circumstances. Aramide air slide fabric, nomex air slide membrane, kavlar air slide membrane The Aramid 1414 air slide fabric which is fire proof, high tensile strength and abrasion resistance, longer service life, the maximum operation temperature resistance even up to 250degree C. Aramide air slide fabric, nomex air slide membrane, kavlar air slide membrane For the aramid 1313 air slide fabric, which is the high temperature resistance air slide fabric as well, this aramid air slide belt continuous operation temperature can up to 200degree C, maximum peaks can up to 220degree C. This aramid air slide belt with shorter operation life and lower operation temperature, but can offer a more economical solutions for some special air slide systems. Aramide air slide fabric, nomex air slide membrane, kavlar air slide membrane Aramid fiber also can be needle punched into nonwoven aramid air slide fabric (Nomex nonwoven air slide fabric) and offer some economical solutions for the air slide systems or homogenization systems. Relevant specification of the aramid air slide cloth from Zonel Filtech: Thickness of the aramid air slide membrane: 3~10 mm can be customized.
