Diesel Engine Soot Particle Filter (DPF) Used in Diesel Engine Tail Gas Purifying System

Product Description

Diesel Particulate Filter
Diesel particulate filter is used to remove black smoke (PM e. G.: Hydrocarbons, soot) from diesel engine exhaust, being a great contribution to the environment because of dealing with the exhaust from diesel engines. The diesel particulate filter can be used in different industrial fields such as
Environment protection, petrol-chemistry, medicine manufacture, and metallurgy etc. It has good investment return and broad prospect. The system installed DPF (Diesel Particulate Filter) been examined for urban bus, forklift, truck & mining constructing equipment.

Characteristics:
*Broad band filtration (the diameters of the filtered particles are 0.2-150 µ M)
*Low back pressure
*High filtration efficiency (can be up to 70%-95%)
*High refractory
*High mechanical properties
