AIR FILTER INDUSTRIES PVT. LTD

Ballygunge, Kolkata, West Bengal

NF-600 NB is our standard range of diffusion ceiling filter media exclusively designed for after market refinishing booths. This is a high quality diffusion filter media, made from 100% branded polyester fiber and progressively structured with reinforced high quality fiber-glass net backing & 100% glued. Specially designed to increase air quality levels above and beyond spray booth manufacturer's recommendation. Removing contamination and providing consistent air flow across the painting surface, eliminating re-do's.

AFi's MPHT Ashrae high-temperature filters are used for air filtration Usage Zone involving temperatures up to 350 Deg C & peaks up to 455 Deg C. The silicone - free filter media are made of special, temperature-resistant glass fiber paper with high mechanical stability and moisture resistance. Mini pleat design separators maintain the pleat distance. Protection grids on both upstream and downstream side also prevent damage to the filter medium. The protection grids and the filter frame consist of galvanized steel, to reduce the risk of particle shedding caused by the constantly high temperatures. AFi's high-temperature Ashrae filters are equipped with a temperature-resistant gasket to preclude leaks.

AFi's imported Roll O matic filters are made of an elastic glass fiber material of progressive construction. This means, that the fibers are increasing in density in direction to the clean air side. Comes with a glass fiber backing mesh and an optional spool.

Our Deep Pleat ASHRAE is a ruggedly constructed, heavy duty, high efficiency filter. A special dual layer, graded density media ensures extremely high dust holding capacity & therefore lower operating pressure loss. The high efficiency and moisture resistance of the filter keeps the inside clean & protects against moisture and salt.

Our HEPA (High Efficiency Particulate Air) filter is constructed from high quality wet laid micro-glass media and uses corrugated aluminum separators. The pleat pitch is designed for minimum air flow resistance and the spacer edges are 'safety rolled' to prevent media puncture. The filter is sealed to the frame with a two - part spongy PU resin to ensure zero leakage and zero transit damage.

Compressor secondary filters are produced with a specially laminated micro glass fiber paper in pleated construction supported with hard tagger aluminum foil as separator. Finally housed in a robust 16g double flange aluminum frame. (Nut Bolt type) In-depth spongy PU resin is provided for zero leakage and zero transit damage.

Our Fiberglass Pocket Filter Media is constructed of an ultra-fiberglass fiber media. The media is bonded to a thin non-woven synthetic backing and sewn with multiple rows of expanded stitching. These medium to high efficiency filters can be used in a variety of commercial and industrial applications as well as specialty applications such as oil mist collection, fume collection and collection of heavy concentrated file airborne contaminants.

The AFi's Bag In Bag Out side loading isolation housing is designed to ensure that the service personnel are protected from coming in direct contact with the unsafe impurities during filter change. Designed to withstand +500 mm wc. Each HEPA filter cell is sealed against the housing frame and furnished with an individual door. A set of repression bags is shipped for use with each door. Once the initial filters are installed and the first bag attached, all filters, both dirty and new, are handled through the bag.

The AFi HV (High Volume) Hepa Filters are developed for demanding Usage Zone. Constructed with a robust aluminum or Galvanized frame and our proven mini pleat technology. The AFi HV offers the ultimate in reliable filtration for the most critical of environments and can be used upto 5000m3hr.

The ZFb series are rigid welded pocket filters consists of a series of synthetic media pocket built up in non woven layers to ensure mechanical 'filter cake' build up & eliminate fiber shedding. The filter media is thermally bonded synthetic micro fibers that are extremely durable and totally resistant to damage caused by turbulent air or mishandling. Made from 100% branded polyester. Pockets are aerodynamically designed for full media utilization.

The AFi HV (High Volume) Hepa Filters are developed for demanding Usage Zone. Constructed with a robust aluminum or Galvanized frame and our proven mini pleat technology.Lower pressure drop conserves energy. High dust holding capacity allows for fewer filter change outs.
