Static electricity can form in dust collector bags due to:

• extremely dry air stream
• air to dust, dust to air, dust to duct movement, all causing static to form
• properties of the dust itself (ie: plastic resins)

Static is potentially hazardous, causing explosions and poor dust release. Solutions include:

• anti-static chemical treatments
• epitropic (carbonized or metalized) fibers
• felt with stainless steel fiber blends
• bags with copper or stainless steel ground wires

Of these, the most effective, under all operating conditions, is BWF ExCharge® stainless steel felt, available in polyester and polypropylene felts. Cake release treatments such as CS17® and SSR can be added to further aid cake release.
