Filter Cartridge for DPF

Model number：

Leelool Purification ensures that the treatment effect of every DPF meets the standard by strictly screening filter material, leveraging long-term project practical experience, and continuously iterating the production of filters.

The performances of a high-quality diesel engine exhaust purifier should be:

1. Low Startup Back Pressure

2. Strong Purification Capacity

3. Long Maintenance Cycle

What determines these performances of the purifier?

The core factor determining the purification capacity of the purifier includes：

1.The material of the filter element

2.The manufacturing process of the filter element

3.The effective filtration area of the filter element

Senior engineers of Leelool develop metal filter element with specific specifications based on the actual working scenario of engine exhaust. Through rigorous screening, 316L stainless steel fiber is used as the filter material.

Structure process

Using a folded wave structure for production and manufacturing,304 stainless steel corrugated sheets are inserted in the middle of each crease.At the same time, stainless steel tie rods and anti collapse auxiliary reinforcement rings are added to connect both ends to ensure the stability of the filter structure.

Welding process

Using high-temperature ceramic adhesive to connect the cover plate and filter material,both ends of the filter material are embedded with 1mm,these steps can effectively prevent corrosion and extends the service life of the filter
