Areas of application

Our filters protect functionally and safety-relevant components so that components and vehicles function flawlessly in all situations.

Advantages

  • Locations in Germany.
  • In-house toolmaking.
  • Certified.
  • Fast delivery.
  • High flexibility.

Filter types

Your requirements are our motivation.
For the best filter.

From bathroom faucets to aircraft nose wheels, our filters can be found practically everywhere. They prevent malfunctions in sensitive units and enable a wide variety of applications to function smoothly. Some of our filters are smaller than a pinhead, yet they are indispensable when it comes to ensuring the functionality of your products.

Production

Your expectations are our benchmark.
From sample filters to series production.

You have invested a lot to make your product successful. It is unique in many ways and can therefore compete on the global market. A filter can protect your product and make it better or safer, if it fits your application exactly. And if it receives the same attention that you gave your product during its development. Let's work together to figure out how we can customize your filter, so that it fits seamlessly into your product.

Example applications

Ensure mobility.
For every vehicle.

Our filter and screen solutions can be found in numerous locations in the vehicle: in the transmission, engine, hydraulic system, and in the oil and fuel circuits. There, they ensure clean media flows, protect components, and contribute to the longevity and efficiency of modern drive systems.

Our Flexi-Clip ensures that the camshaft adjustment functions correctly, thereby contributing to the smooth power delivery of the engine. Its special geometry enables easy and secure installation.

Our injector filter protects the injection valves from damage and malfunction and ensures reliable operation of the injection system. Fine mesh and a clamping ring provide reliable particle protection and optimal fixation.

Our ABS filter helps ensure that the valves in wheel brake cylinders function reliably in braking systems
and that vehicles remain controllable even during emergency braking. The high-quality combination of metal mesh and plastic frame is particularly pressure and media resistant.

With its large filter surface area in a compact design, our AdBlue filter reliably protects the dosing unit from contamination, ensuring effective exhaust gas aftertreatment in diesel engines.

Our combination filter protects the solenoid valve control in automatic transmissions for fast and smooth gear changes in every driving situation. It performs both sealing and filtering functions, requiring little installation space and minimal assembly effort.

Key Facts

We stand for quality.

When you have us manufacture your filter, you are entrusting us with an important role in your product's value chain. Our awareness of this responsibility is reflected in all our processes and standards.

Brake system

Our filters play a crucial role in a car's ABS, ASR, and ESP systems by filtering contaminants and particles out of the brake fluid. This extends the service life of the brake components and improves the reliability of the brake system, which ultimately contributes to the safety and performance of the vehicle.

Fuel system

  • Screens for AdBlue applications for selective reduction of nitrogen oxides in exhaust gases (DeNOx systems) during exhaust gas aftertreatment
  • Tank suction screens to protect the fuel pump and fuel system
  • Screens for fuel injection valves and fuel pumps
  • Screen filters for fuel pressure regulators

Our filters in the fuel system protect automotive components by removing dirt, rust particles, and other contaminants from the fuel. This ensures, for example, that only clean fuel enters the injection system – for smooth engine running, less wear, and maximum efficiency.

Engine control

  • Ultra-fine filters for hydraulic controls protect valves by filtering dirt particles out of the hydraulic system.
  • Screen discs in mass air flow meters ensure precise air supply, thereby improving measurement accuracy.
  • Screens for turbochargers help maximize service life and efficiency by removing foreign particles from the air supply, thus preventing damage to the turbocharger.

Transmissions

  • Screen filters for automatic transmissions
  • Screen filters for dual-clutch transmissions
  • Valves and throttles in transmissions, engines, and hydraulics

As a manufacturer of filters and screens, we offer customized solutions for the most demanding requirements in drive technology. Our screen filters are used in automatic transmissions and dual-clutch transmissions, among other things, where they ensure reliable filtration and system protection. In addition, we supply precisely matched valves and throttles for applications in the transmission, engine, and hydraulic sectors.

Oil circuit

  • Screen filters for the oil supply circuit of combustion engines

Our screen filters for the oil supply circuit of combustion engines ensure reliable separation of particles, thereby protecting sensitive engine components from wear and damage. They are precisely tailored to the requirements of modern engine technology and guarantee consistently high oil purity during continuous operation.
