P84 Needle filter felt bag

1, trilobal cross-section for high filtration 2, working temperature up to 260 3,easy of cleaning and longer working life

Detailed Product Description

P84™ fiber has unique characteristics that give it better dust collection efficiency. The irregularly shaped trilobal cross-section provides a larger specific surface area than round, bean-shaped or rod-shaped fibers. DWS selects INSPEC FIBERS polyamide fibers from Austria LENZING Company to produce the high temperature needle filter felt. In some cases we combine P84 fiber with other fibers to produce a composite needle felt.

 

The characteristics

 good heat-resistance: operating temperature up to 260°C.resistant to most organic solvents, acids, fats and fuelshigh filtration efficiency, low pressure change, and ease of cleaning.good abrasion resistance and chemical stability,longer working life.
