HJS CityfilterSMF-CRT HJS diesel particle filters guarantee clean air. They hold back the soot particles effectively in their interior, including fine-grain dust, and clean themselves of deposited soot continuously and autonomously. The sintered metal filter technology developed by HJS and distinguished with the German Environmental Prize guarantees this. HJS filter solutions are TÜV approved and…
Sintered Metal Filter with External RegenerationSMF-ER® It is vital that the correct diesel particulate filter system (DPF) is selected for short term use. These applications can be retrofitted with the HJS SMF® ER system in order to remove harmful soot particles from the exhaust. The SMF® ER system is characterised by its easy installation and…
Exhaust pipes & repair pipes HJS offers all usual frontal and intermediate pipes as precisely-fitted series replacement of the exhaust pipes. With defects in ex-works, high-cost exhaust gas components, such as catalyzers or particle filters, HJS offers an upkeep maintenance solution in line with current value. Material weaknesses, cracked and leaky flexible parts, or also…
Exhaust manifold As a sensitive, flow-relevant, component part of the exhaust gas system on the internal combustion engine, the exhaust manifold is responsible for collecting the exhaust gases expelled from the individual cylinders and routing it as required. In this case, a demanding task is placed on the complex and flow-technically optimised component part. Both…
Universal parts & repair solutions The HJS program includes approximately 500 universal components in the highest quality for all market-relevant exhaust gas systems. With the universal parts, damaged exhaust gas systems can be repaired, also partially, and thus at low cost. In special vehicle construction, HJS even offers with this program the possibility to generate…
Flexible pipe connector Flexible pipe connectors serve for the improvement of flow characteristic behaviour and consist completely of high-quality stainless steel. The exactly co-ordinated component parts enable maximum service life, even with extreme temperatures. Even a guarantee of 3 years is granted by the improved quality of the HJS-interFLEX. Illustration see below “HJS-interFLEX” further illustrations…
Pipe connector The most important task of a pipe connector is to connect two exhaust pipes with each other reliably and gas-tight. Both requirements are met with the highest precision by a HJS pipe connector, consisting of high-quality stainless steel and a double-walled jacket. In addition, overlapping clamp heads provide for a uniform frictional connection…
Installation sets HJS installation sets include all materials required for the installation, which are put together as required for the respective exhaust gas components. This minimises the time expenditure in the workshop for the procurement of individual parts. The installation sets are designed according to the desires of the customer or according to the specifications…
Assembly technique individual parts With more than 1,500 references, HJS offers one of the largest product ranges of individual parts for exhaust gas installation technology on the market. HJS installation technology is characterised by high fit accuracy, long stability and precise processing. The product range of high-quality individual parts offers not only vehicle-specific seals, sealing…
SCRTSCRT® As early as the 1990s, soot particles could be eliminated from diesel exhaust gases down to the detection limit. HJS has specially developed the diesel particle filter from sintered metal (Sintered Metal Filter SMF®) for this and received the German Environmental Prize for it. For the reduction of the gaseous pollutants, in combination with…
