We are offering nonwoven pocket filter, synthetic hot welded pocket filter we called rigid bag filter, the filter media of the our compact pocket filters are made of break-resistant synthetic-organic fibers and microfibers - no glass fibers. The filter pockets are leak-free welded and foam-sealed into the front frame to preclude dust breakthrough. High dust holding capacity and long useful lifetime are ensured by the single- or multi-layered progressive structure of the filter media as well as the inherent rigidity of the filter pockets. The low average pressure drops and optimized aerodynamics together with full utilization of the filtering area available result in reduced energy costs. Jm rigid pocket filters ensure maximized functional reliability even under temporary overloading and are maintenance-free over their entire operational lifetime. They are non-corroding, moisture-resistant up to 100% relative humidity, thermally stable up to 70c, and disposal-friendly. Jm welded pocket filters are microbiologically inactive and meet all hygiene requirements for hvac systems.

We are offering hepa filter, our separator air filters as final filter used in clean-room, can meet critical requirements on air purification from class 100000 to class 100 at normal temperature. On the basis of features of chinese market, hepa air filters with variable moulds and with different test methods are available, which can reach ideal life-time and ensured efficiency at various operation conditions with rational protection from pre-filters. This alum.separators or clapboard separators hepa filter with metal frame or with plywood frame passed all dop scanning test. Features: * low initial resistance with high efficiency at rated volume.* easy installation and guaranteed sealing performance.* no particle shedding from filter itself after dust-proof process, thus with high safety of cleanness.* frames can be chosen from galvanized-steel, aluminum and stainless sheet.* separator: paper or aluminum.

We are offering roll air filter, ceiling filter "longwell"air filtech's diffusion media are synthetic fiber-based nonwoven filter products developed at our own high - tech production facility. The filter media are constructed from selected high performance fine denier fibers in a gradient density multi - layering technique to ensure high depth loading with optimal lowest pressure drop performance. These media are thermally bonded and impregnated in full depth with a special adhesive coating to prevent any release of fibers and migration of paint - damaging particles larger than 5 microns due to vibration in the system, even under varying temperature conditions.advantage:dvantages made from high performance, 100% unbreakable synthetic fibers. Which means no fibers breaking into the air stream. The ceiling media is 100% impregnated with a special adhesive. Each fiber is impregnated. Not dry in the center. Will not shed dust even during sever vibration. Progressive density construction (graded density). Din logo impregnated. Available in three different variety. Available sizes custom made as per customer request. Application: car plants 2 wheelers trucks & lcv after market booths / body shops
