Industries throughout the world rely on fabric dust collectors to remove particulate from process & ventilation air and to recover valuable resources from any manufacturing process. RATHI INDUSTRIES, fabric dust collectors add a dimension of versatility & diversity with a multitude of designs, thus allowing you to select the best model to solve your dust control needs.


Rathi’s are totally committed to the filtration industry & is the only completely integrated supplier in INDIA, we convert pure fibre into filtration fabrics, which are fabricated by hand into high efficiency filter bags.
Rathi’s filter bags attain an efficiency of 99.9% on the sub-micron particles as low as .4 micron & can solve the following performance problems.

  1. High separation at start up & during operation
  2. High separation efficiency at high air to cloth ratio allows for large increase in productivity
  3. Low resistance to flow generates high airflow rate & low-pressure build up.
  4. Low pressure build up means less frequent cleaning. Reduced cleaning pressure yield significant decline in energy costs.
  5. Reduced cleaning pressures mean less stress on fabric resulting in less stretching & hence lower replacement cost.
  6. Lower propensity to blind results in longer service life & hence reduced replacement cost.
  7. High air to cloth ratio means less number of bags in a smaller dust collector resulting in capital lost.
  8. Chemically inert & thermally stable to high temperatures.
  9. Can be implanted into available pulse jet systems, reverse air & mechanical shaker systems.


Without a finish or protective coating the gas filaments in filtration fabrics can break when flexed during normal usage. Breakage results from flaws forming on the surface of glass filaments flaws can be created by abrasion or chemical attack. Finish selection should be made on the basis of the flew gas chemical composition and type of particulate.
373 CHEMICAL FINISH: this uniquely formulated finish is composed of a polymer, which prevents chemical attack on the glass filaments and PTFE (polytetraflouroethlene), which provides superior abrasion resistance. It is based on a unique PTFE dispersion, which has been formulated to promote covalent bonding and coalescence of the PTFE particles. The finish is resistance to both acid and alkali attack & provide superior abrasion resistance

580 TRIPLE FINISH: the triple finish was one of the earliest finishes developed for filtration fabrics. It consists blend of silicon oils, graphite & PTFE. The three finishes components combine to protect the glass fabric from abrasion, but offer only limited protection from chemical attack. the triple finish is now used primarily in cement production and metal foundry applications.

615 PTFE:
A ten percent add on of PTFE particles, such as DUPONT”S TEFLON B, encapsulates the glass fibers to prevent abrasion. However, because PTFE does not bond to the glass filaments, acids or alkalis can attack fabric with a PTFE finish chemically. Fabric with 615 finish is recommended for use with utility base load boilers Operating under mild PH conditions.

625 ACID RESISTANCE: this proprietary finish consists of acid resistance polymers, PTFE GRAPHIT & SILICON OILS. The acid resistance polymers form a covalent bond with molecules on the surface of the glass. The bonded polymer forms a protective barrier around the glass surface to shield it from chemical attack. The acid resistant finish is recommended for filtration of flue gases in an acid environment such as carbon black  & industrial utility boiler
