Filtr paliwa Master 4506.005

A fuel filter of this type is installed in the fuel supply line between the tank or supply source and the burner components (pump, gas valve, or nozzle). Its function is to remove solid particles, rust, and other contaminants that could clog small orifices, damage valve seats, or cause irregular combustion. In oil-fired burners, a clean filter prevents nozzle blockage and pump wear; in gas-fired appliances, a dedicated gas filter protects the gas valve and pressure regulator. The filter is typically placed upstream of the solenoid valve or the oil pump, often with a shut-off valve on each side for service access. Such filters are selected by connection size (thread type and diameter), filtration rating (micron size), and flow capacity relative to the burner’s maximum fuel consumption. Pressure drop at rated flow and the material of the filter element (paper, sintered bronze, stainless steel mesh) also matter, especially if the fuel is viscous or contains water. When replacing a filter of this kind, verify the thread pitch and sealing method (taper or parallel threads, flat or O-ring seal) to avoid leaks. Also check the filter housing material compatibility with the fuel – for heavy oil, a cast iron or steel housing is common; for light oil or gas, aluminium or brass may be used. Regular replacement intervals depend on fuel cleanliness and appliance usage. A clogged filter will cause loss of burner output, erratic flame, or lockout due to low fuel pressure. Always close the fuel supply before servicing, and bleed the line after replacing the element if the system is oil-fired.
