Primary bag air filter, also called pocket air filter,is made of three parts: the filter frame, sewn-in pockets and pocket rings, and it is commonly used in the first or second stage of the filtration system. Primary bag air filters can be designed in various sizes and also can be produced with various pockets or bags. Because of its special design, it can offer more than five times surface area than flat filter. A multilayered, melt-blown polypropylene medium is used to make the individual pockets. To ensure that the air flow is distributed evenly across the entire filter, pockets are made to inflate and stay apart from one another. Primary filters are intended to catch floatable particles larger than 5 microns. While it is possible for the primary filter to capture what the pre-filter captures, doing so would significantly decrease the efficiency and efficacy in capturing the tiny airborne particles. This pocket type filter will not be distorted, or twisted when used normally, thereby extending the service life of the product. Every pocket is fully sealed, so it can avoid any dust or air leaks. Advantages Longer service life due to low initial pressure drop. Widely available in a variety of sizes, pocket counts, and pocket materials. For varied purposes, there are many different and broad filtering efficiencies available. Simple to use, maintain, and take away.

Nylon Mesh Primary Air Filter

Application field: it is used for centrality air conditioner and purifying equipment which is initial filter. Carton packing, then several cartons by one pallet.

Af (pre filter / coarse filter / air filter) is a blue-white filtering material mainly applicable for absorbing large dust particle in the air to prevent blockage in medium- and high-efficient filter so as to prolong their service life and efficiency. Since it adopts super-hard fiber which is coated with stable glue, it has higher hardness and density, better pre-filtration effect and higher air flow rate.

It is a high-arrestance paint-stop filter made of high strength glassfibre with gradual density, inlet side is green, and outlet side is white. Low compressibility keeps its shape and makes fiber purified air effectively. It can absorb effectively the excess particles during paint-spraying operation and reducing pollution to the environment, makes the exhausted air more environmentally-friendly and inner circulating air more cleaning. It's especially suitable for heat reclaimer, widely applicable to automotive/furniture paint spray booth, coating production line, etc. Model: lh-260g Specification: general stock in width: 0.75m, 0.8m, 1m, 1.25m and 2m, optional lengths.

This activated carbon panel filter can be used to dealing with smell in the air and pollution, widely used in air filtration of ventilation for chemical, electronic, pharmaceutical, food, hospitals and other industries. Style Acpv-1 acpv-2 Style:acpv-1, acpv-2 Dimension h*w*t (mm):295*595*600, 495*495*600, 295*495*600, 295*295*600 Frame:galvanized iron, aluminum alloy.

Az (pre filter / coarse filter / air filter) is a filtering material mainly applicable for absorbing large dust particle in the air to prevent blockage in medium- and high-efficient filter so as to prolong their service life and efficiency. Models: Az-150g, 200g and 300g; Af-200g; Specification: general stock 1m*20m, 1.25m*20m, 1.6m*20m, 2m*20m. Also make according to customerf+s order.
