FS Series

The Donaldson FS Pulse Jet Baghouse dust collector and bin vents are economical solutions for dust collection and bin venting applications. The side filter bag removal allows for installation in low headroom applications.
  • Side bag filter removal allows for installation in low headroom applications
  • All-welded construction provides increased durability and air/water integrity
  • Integral fan option up to 75 HP helps to reduce space requirements
  • Unique cleaning system minimizes moisture and particulate issues in pulse valves
  • Collectors with up to 225 bag filters require only one dirty air inlet, one clean air outlet, and one hopper, resulting in reduced ducting and hopper outlet costs

Two Breakthrough Filter Options for Your FS Pulse Jet Baghouse

Dura-Life Bag Filter

Dura-Life® Filter Bags Provide Twice the Life Over Standard
540 g/m2 / 16 oz/ydPolyester Bags

Traditional 540 g/m2 / 16 oz/yd2 polyester bags are produced via a needling process that creates larger pores where dust can embed into the fabric, inhibiting cleaning and reducing bag life. Dura-Life bags are engineered with a unique hydroentanglement process that uses water jets to blend the fibers. This process creates a felt with smaller pores which keeps more dust on the surface of the filter resulting in better pulse cleaning and longer bags life.

  • Two to three times longer bag filter life
  • Reduced maintenance and replacement bag filter costs due to fewer bag changeouts
  • Fan energy savings due to lower pressure drop
  • 30% fewer emissions based on EPA tests
Ultra-Web SB Pleated Bag Filters

Pleated Bags with Ultra-Web® SB Provide Longer Life and
Reduced Emissions

For more than two decades, Donaldson Torit has advanced the proven Ultra-Web nanofiber technology. Ultra-Web provides a very fine, continuous fiber of 0.2 - 0.3 micron in diameter to form a web-like net that traps dust on the surface of the media. Combining Ultra-Web technology with a sturdy spunbond polyester substrate, Ultra-Web SB pleated bag filters provide longer life, reduced downtime and reduced emissions.​​

Ultra-Web SB Pleated Bag Benefits:​

  • Reduced collector size and first cost
  • Up to two times longer filter life
  • Energy savings due to lower pressure drop
  • Reduced maintenance and downtime costs
  • Reduced emissions​​

Q. What Is a Hydro-Entanglement Process?

A. Instead of a mechanical process using needles to entangle and compress polyester fibers into a felt material, the hydro-entanglement process uses jets of water to entable and compree the polyester fibers into felt. The process creates a material that is more uniform and provides better filtration.

Q. How Are Dura-Life Bags Different from Standard Polyester Bags?

A. Dura-Life bags are made from polyester material that is created through a hydro-entanglement process instead of a needle punch process. The hydro-entanglement process creates a more consistent and uniform filter material. The material is comparable in thickness to standard polyester, but weighs about 1/3 less. The fibers are smaller and the hydro-entanglement process creates a loftier and lighter weight fabric that filters more effectively.
