PULSE JET FILTER BAGS

HARSHDEEP manufactures Pulse jet filter bags, plenum pulse filter bags from sophisticated non woven needle felt – The material which brings high performance and strength .These bags are manufactured in its own modern manufacturing unit, with a unique 3 - needle chain stitch to insure seam integrity. Our manufacturing unit is well equipped with all modern cutting, sewing and measuring equipments. HARSHDEEP can custom design and fabricate a filter bag to meet your needs by examining a sample, print, sketch, or verbal description of the bag. We also offer equivalent replacement filter bags, and can recommend improvements to an original OEM bag. By means of HARSHDEEP specialized finishing procedure it is possible to tailor the final product to have different or additional proportion to fulfill even the most demanding of applications.

Pulse jet with all type of top mounting like snap ring, rigid ring, Collar plain open are manufactured by our engineering department as per the requirement of the equipment. Few amongst our wide range of Pulse jet bags are shown below:

E       Plain top, disc bottom with ground wire

F        Snap band top, disc bottom

G      Plain top, disc bottom

Dust Filter bags are also available in fabrics with special surface Coatings & Finishes like:

       1)Plain: Natural finish. General purpose material.

       2)Singed: Accomplished by exposing media to open flame to burn off any loose fibers. Improves dust cake formation.

       3)Glazed: Accomplished by running media over hot roller which melts fibers and results in a smooth "eggshell" finish. Improves dust cake release.

       4)Acrylic Coated: Air permeable acrylic surface coated polyester for moist environments.

       5)Flame Retardant: Not flame proof, but provides a self extinguishing feature that is used when sparks are involved, such as grinding processes.

       6)Teflon Membrane: Membrane provides an extremely smooth, high efficiency finish.

       7)Fiberglass: High temperature, chemical resistant woven fabric.

       8)Spark resistant

       9)Anti adhesive

       10)Micro porous

       11)Anti acid and other special finishes

 HIGH TEMPRATURE DUST FILTER BAGS

If your collector gas stream is (150C – 260C) degrees C , our engineers can select the correct high temperature media that is compatible with almost any gas stream. We avail filter bags that function effectively at high temperature (150C – 260C) in combination with strong acidic or

 alkaline mixtures. Available media with us are  Teflon and fibre glass. Whether it's a replacement order or a new application.

FIBER GLASS DUST FILTER BAGS

The glass fiber filter bags are made of glass fiber woven fabric that is special treated. The product has good heat resistance and used at 260C for a long time. It is ideal heat resistance filter materials and has good stable size with good chemical resistance, anti-water, anti-moistures and excellent dust peeling properties. The filtering efficiency is more than 99.5%. The glass fiber filter bag has been widely used in cement, carbon black, electric power and metallurgical industries for removing dust in the conditions of high temperature.

HARSHDEEP has the experience, knowledge & equipment to produce high quality and high performance fiberglass filter bags. Our high - tech fabrication equipment is the standard of the industry. It produces straight bags sewn under tension. No banana effect & minimum manual handling product quality & add to its life. 

PLEATED FILTER BAGS

Pleated bag filters are engineered to fit various size dust collectors and are fabricated to ensure ease of installation and change-out. Pleated bags are easily mounted into various size cell plated for both top and bottom load dust collectors. Pleated bags are designed to replace fabric bag filters and cages used in many dust collectors.

There are several benefits of using Pleated Filter Bags:

       Ease of Installation

       Reduced Maintenance Cost

       Efficiencies up to 99.97%

       Higher Air Flow Per Filter Unit

       Fewer Change-Outs

       Better Resistance to Inlet Abrasion

       Up to a 5-Fold Increase in Surface Filtration

       Washable Exterior

       Minimizes Compressed Air Usage

PTFE MEMBRANE LAMINATED FILTER BAGS

We offer PTFE membrane laminated filter bags to counter the disadvantages of conventional "depth filtration" media. In conventional media the felt fabrics act as a media for the built up of a dust cake, which in turn captures even more & finer particles of dust. The filters are cleaned continuously to remove some of the dust cake & then begin the process all over again.

PTFE membrane laminated on filtration side of filter media permits air to pass through the filter media while trapping all particles on surface. Membrane laminated filter bags are termed as BACT (Best Available Control Technology).

The membrane laminated filter bags do surface filtration where the filtration is done by a micro porous PTFE membrane which is laminated to a process compatible filter media. The support media provides the physical strength to fabric whereas filtration is done by the membrane. The phenomenon is termed as surface filtration and has following advantages:

·         Consistently lower pressure drop throughout the life of the filter bag.

·         Lower outlet emissions.

·         Can take process upsets more easily & thus reduce downtime.

·         Generally the life is double then a conventional filter bag if all other things in the bag house remain same.

·         Lower operating & maintenance cost.

·         Great product recovery
