Filter holding frames are made of Ltype steel bars welded together to the rectangular frame shape and consisting of zinc coated carbon steel resp. stainless steel. With adjustable tension springs the frames are perfectly suited for installation of all commercially available pocket filters, compact filters or for filter combination systems. The header frames of the filters are going to be formclosed fixed inside to our holding frame at 4 edges by help of 4 tension springs. With 2 detents and 2 spring centre points the filters inside the holding frame can be safely bend, at height of 25 mm and 50 mm ( 1 and 2 inch ). From the filter holding frames a complete filter wall can be easily & fast established by simple screwing together. On request stainless steel versions are available.

Isolation tapes are available in different material like open molecule polyethylen, polyurethane, closed molecule rubber, EVA, PVC and semiopen molecule rubber single and double side sticking tapes. They are used by airconditioning units and climate rooms to guarantee air tightness

Paint calibration cloth and bags are usually used in different cloth and nonwoven as filters according different “MESH” sizes in various forms according customer requirments

They are produced from Needlefelt (temp. resistance 80100ºC) or glassfiber material (temp. resistance 350600ºC) or ceramic cloth material (temp. resistance 8001000ºC) and used in coal mines and power units in different sizes.

There are various types of cylindrical and semicylindrical natural gas filters and they have various type of filters starting from filter paper to nonwoven synthetic media upon customer needs.

Although the operation principal of these cylindrical filters are similiar, they have a bright product variety. The cylindrical filters are produced from material with synthetic nonwoven and cellulose content which has resistance against heat and humidity. Material like Glass fiber and paper with polyster are used by the production of these filters where they are used in several production process machinery as blower and suction filters.

These special filters are used by factories at CNC departments, parts washing units where temperature, humidity is high and the air must be filtered and clean. Here there are so many different expectations from customer side, usually they are produced according customer request in size and filter material.

Temperature/Oven/Furnace Filters are used in industry like drying units, Paint cabins where high temperature and airflow and capacity is required. Generally two class and grades are used Class EU4 (200°C) and Class EU5 (300°C) and avarage efficiency is 43%.

Filter bags are manufactured for optimum filtration performance. They are made from carefully selected media developed specifications the process industry. Various types of media are used such as needle felt, monofilament and multifilament. They are effective in reducing dust emission level as requirement of industries. These bags are placed in dust collector with supporting filter cages. Contaminated air takes path of outside to inside filtration. All solid contaminants get deposited at outer surface & clean air / gas passes through top chamber. Particles retained at outer surface of media get collected at bottom of dust collector with help of shaking mechanism or reverse pulse jetting mechanism.

Pleated dust collection cartridges are made of 100 % polyester media, metal or teflon treated material like pleated dust collection bags media with different coatings on it, as per requirement of applications. Pleated dust collection bags & cartridges are one & same. Manufacturer of dust collectors originally designed to build the dust collection cartridges in equipment, where as pleated bags can be used for existing dust collector in place of conventional dust collection bags, without modifications. This polyester media is made of high tensile filament yarn without using any binding agent. Thus hard finished material is very stable against hot gas attach & structurally durable. This unique & hard finished material provides features of good pleat ability, high durability

Air filters with activated carbon are classified under 3 topics according their filtration sensitivity. They are as follows; Active Carbon absorbed Foam Cassette Filters (pleated or without pleating), Cylindrical Activated Carbon Filters and Activated Carbon Kompakt Filters. Active Carbon absorbed Foam Cassette Filters are used without pleating, but in places where more filtration surface is required pleated version is preferred and used in Standard and special sizes upon request. According system necessity cylindrical filters with activated carbon are produced and used in different places. Compact Filter with activated carbon achieve a high surface area in little space and therefore a long lifetime under economical operating conditions. .

Hepa Filters are mainly used in hospitals, pharma industry, nuclear industry, electronics and microelectronics where high air quality is required. Toxic dust, aerosols, bacteria, virus similiar particles are captured with hidrofobic type glass fiber filter paper pleats formed and mounted with aluminium seperaters. There are different technics by pleating the most effective is the mini pleat system which ables the highest filtration with lowest pressure drop. The filter Classes are H10 to H14 according EN1822. Metal frames are available in different materials like aluminium, 304SS, 316SS. Hepa Filters are produced in Standard sizes (see the chart down below for details), also upon customer request in special sizes.

Compact filters are used in hospitals, airports, museums and industrial applications where medium and high quality airflow is required. These filters are used as primary and/or main filters to prevent toxic gas, aerosol and general dust pollution. They are especially suited for for handling large airflow volumes and achieve long service life times due to their large dust storage capacity. By their production different materials are used like water resistant glass fiber filter paper pleated and mounted in Vform frame. Pleats are formed and fixed with thermoplastic seperaters. Due to this special design dust are hold and spread homogen between the pleats. Their filtration quality is high and pressure drop low. For special cases Aluminium seperaters are used and such types have high capacity

Bag filters are used by clean air requirments as pre and final filter. Pocket filter are made of non woven synthetic, fiber media to ensure retention of solid particles up to stipulated micron rating. These are covered with supporting layer of spun bonded media to avoid any type of particles or fiber migration, even after high pressure build up and mounted in special frames. The filter frames are from plastic or galvanisied metals. According EN779 Bag Filters goes from F5 to F89 Class available in various pocket length and quantities

Fan Coil filters are produced from similiar material like synthetic nonwoven, glass fiber, filter foam which are used by casette filters as well, in standard or special sizes upon customer request and fitted to metal frames after tightness test. They are usually used as prefilters by central ventilation systems.

Opencell or closedcell polyurethane foams are available in all common densities and in different colours. The elastic polyether foams show a relatively high resistance to acids and caustic solutions. In addition, they are much more resistant to hydrolysis and ageing than polyester foams. Accordig to a special process called reticulation is used to subsequently open the pores to almost 100%. By this a pore structure of even, opencell filter foams in controlled pore sizes of between PPI 10 up to PPI 80 can be achieved (PPI = Pores per Inch). A benefit of the polyester foams is their shockdamping property. In addition, polyester foams are less susceptible to light ageing than polyether foams.

Glass Fiber Rolls are produced from nonflammeable fibers and not suitable for washing and have progressive structure in direction to clean air side. They are used mostly by paint cabins as bottom fitler to hold paint mist and as prefilters mounted in different types of cassets. Dust holding efficiency vary from 82 to 97 %. In addition there are other class of Glass fiber rolls used by drying ovens and cabins with high temperature air circulation. They are classified according EN779 from G3 to F5

Synthetic Fiber Roll Filters are formed as a result of thermal bonding of synthetic fibers without using any binders or adhesives. They provide low pressure reduction and high dust holding capacity, as well as obtaining an effective filtration thanks to the pore structure that tightens towards the air outlet direction. Although some types can be washed and reused, most of them are disposable, providing healthier filtration performance. It is available in different grades from G3 to F5. They are not affected by moisture and contact with chemicals; have high physical strength. They are used as prefilter and precision filter protective filter in Paint Booths, Central Ventilation systems.
