ELEKTROGAS filter Germany ELEKTROGAS model ELEKTROGAS price

ELEKTROGAS filters remove solid contaminants such as iron oxide and dust contained in fuel to prevent fuel system blockages (especially injectors). They reduce mechanical wear, ensure stable engine operation, and improve reliability. Even if diesel fuel has undergone settling and filtration before being added to the diesel engine tank and is clean, it can still be contaminated during refueling due to unclean refueling tools, refueling environment, and tank openings. Furthermore, during diesel engine operation, impurities deposited in the fuel system and suspended dust in the air can also contaminate the diesel. Therefore, an on-vehicle diesel fuel filter is essential, especially since diesel fuel is not necessarily truly clean before being added to the tank.

ELEKTROGAS filter features

Installed on the pump suction line, it filters out residual contaminants in the tank and pollutants entering through air vents, serving to protect the pump. However, to avoid cavitation in the pump, pressure loss must be carefully considered; generally, coarse metal mesh or crimped wire materials with a purpose of 100–200 are used. Therefore, it is not a filter for controlling contamination concentration in the control system. It overcomes many disadvantages of filtration products, such as low dirt-holding capacity, susceptibility to clogging, the need to disassemble and clean the filtering section, and the inability to monitor filter status. It features the function of filtering raw water and automatically cleaning and discharging dirt from the filter element. The system supplies water continuously during cleaning and discharge, allows monitoring of the filter's working status, and has a high degree of automation.

ELEKTROGAS filter function

The core technology of the high-efficiency automatic gradient density fiber filter with asymmetric fiber filter media structure is the use of asymmetric fiber bundle material as the filter media. One end consists of loose fiber strands, while the other end of the fiber strands is fixed within a solid core of higher specific gravity. During filtration, the solid core with higher specific gravity compresses the fiber strands. Meanwhile, due to the small size of the core, the uniformity of the void fraction distribution across the filtration cross-section is not significantly affected, thereby improving the dirt-holding capacity of the filter bed. This gives the filter bed the advantages of high porosity, small specific surface area, high filtration speed, large dirt-holding capacity, and high filtration precision associated with fiber filtration. When suspended solids in water pass over the surface of the fiber filter media, the adhesion force between the suspended solids and the fiber bundles, under the influence of van der Waals forces and electrostatic effects, is much greater than the adhesion force with quartz sand, which helps to increase filtration speed and precision.

ELEKTROGAS filter installation requirements

Install at the pump oil suction port: Surface-type oil filters are generally installed on the pump suction line to filter out larger impurity particles and protect the hydraulic pump. The purpose of installing a filter here is to remove contaminants that may invade components such as valves. A safety valve should also be installed to prevent filter clogging. Install on the system return oil line: This installation provides indirect filtration. Generally, a back-pressure valve is installed in parallel with the filter; when the filter clogs to a certain pressure value, the back-pressure valve opens. Install on system branch oil lines. Separate filtration system: Large hydraulic systems can have a dedicated hydraulic pump and oil filter to form an independent filtration circuit. In addition to the oil filters required for the entire hydraulic system, a dedicated fine oil filter is often installed individually in front of some important components (such as servo valves and precision throttle valves) to ensure their normal operation.
