HJS develops, manufactures and markets a range of highly innovative particulate filter solutions for both the OE and retrofit markets. Thanks to their modular construction, our products can be adapted to create a range of different versions to suit different applications.
Whether it be the HJS City-Filter® for cars, vans and motorhomes, or the SMF® sintered metal filter as a 100% filter system for a variety of commercial vehicles (such as public transport buses, trucks subject to toll charges, and public service and refuse collection vehicles) or for mobile machinery and stationary applications, we have the right system to meet your specific needs.
The centrepiece of all HJS exhaust treatment systems is the sintered metal filter (SMF®). The SMF® and the systems based on it are exceptionally reliable in operation, low on maintenance and also benefit from a long service life.
