DPF (Diesel particulate filter)
Ceramic Filter Product Characteristics

SiC Ceramic Filters

TYK's SiC ceramic filters are used for DPFs in large vehicles equipped with diesel engines and for ceramic filters in diesel generators. By controlling the pore distribution, they achieve low-pressure loss and high PM (particulate matter) collection performance. They also have excellent thermal shock resistance due to their high strength, low thermal expansion, and high thermal conductivity, ensuring a long lifespan. 
Note: TYK's DPFs do not contain catalysts.

High 
Durability

SiC material has high strength and is resistant to thermal shock, providing excellent durability.

High Thermal Conductivity

With high thermal conductivity, heat spreads quickly throughout the entire filter.

Environmental Contribution

Boasting high dust collection performance, these filters support clean air worldwide.

TYK's SiC Ceramic Filter Features

 ​SiC Material with High Thermal Conductivity and Thermal Shock Resistance

SiC (Silicon Carbide) is a ceramic material that excels in thermal conductivity and thermal shock resistance compared to other ceramics. Its durability makes it a highly reliable choice under stringent conditions.

 ​Controlled Internal Pore Distribution

The filter’s controlled pore distribution ensures that the surface of the filter wall has small pores that trap fine particles, while the larger pores inside the wall reduce air resistance.

Supports Small Lot Production

We cater to small lot and multi-shaped product requirements, even accommodating orders for a single filter. Feel free to reach out to us for your specific needs.

Applications

DPF (Diesel Particulate Filter) Designed to remove particulate matter from the exhaust gases of diesel engines, our filters have a proven track record in large vehicles such as buses, trucks, construction machinery, and diesel generators.
