Gas Filters
Gas filters - for protected gas systems in motorhomes or caravans. Here you will find complete gas filters, matching filter inserts, replacement cartridges and brackets - exactly for use on the gas pressure regulator and a permanently clean gas supply.

Gas Filters
Reliable gas filters keep your caravan or motorhome appliances running smoothly by trapping oil aerosols and particles before they reach the regulator, valves and jets. With the right housing, pads and maintenance routine, you protect pressure stability, reduce soot and extend component life across your camping gas system.
Caravan And Motorhome Gas Filters Basics
Install the filter on the high-pressure side, directly upstream of the regulator, following the marked flow direction. Use certified housings and genuine filter elements, and position the unit where you can see and service it easily at the pitch.
Why Gas Filters Matter
Oil residues from LPG and tiny particles can clog regulators and jets, causing yellow flames, uneven heat and nuisance shutdowns. A quality filter catches these contaminants before they cause issues.
Choosing Filter Media
Common options include replaceable pads and fine mesh elements. Pads offer quick, low-cost swaps; mesh elements prioritise long intervals and consistent flow. Match the element to your usage pattern.
Installing Gas Filters: Positioning And Direction
Mount the housing upright if specified, with arrows aligned to the gas flow. Keep pipe runs short and avoid tight bends that create restriction. Leave tool clearance for seasonal services and leak tests.
High-Pressure Vs Low-Pressure Placement
Most systems place gas filters before the regulator on the high-pressure side. Only use low-pressure filters downstream if the manufacturer explicitly permits it for your setup.
Protecting Seals And Threads
Confirm thread type and direction, including left-hand where used. Fit the specified gasket or cone seal, tighten to spec and recheck after your first drive.
Gas Filter Maintenance And Service Intervals
Inspect elements at season start and after long trips. Replace pads when discoloured or oily, and renew O-rings that appear flattened or cracked. Keep spare pads and gaskets in labelled bags for quick roadside fixes.
Symptoms That Point To The Gas Filter
Yellow or lazy flames, pulsing burners and regulator icing under normal load can indicate contamination. Check filter condition, then verify regulator output and burner jets.
Clean Handling Practices
Wear clean gloves, keep dust caps on open ports and avoid touching filter media with oily hands to preserve performance.
Flow, Capacity And Compatibility For Gas Filters
Match filter capacity to total appliance load. An undersized filter can restrict flow at peak demand. Choose housings and elements approved for LPG and compatible with your operating temperatures.
Twin-Cylinder And Changeover Systems
On twin-cylinder setups, install the filter so both cylinders feed through it. Keep pigtails short with gentle curves and label lines for fast swaps.
Monitoring Performance
If available, use a simple manometer or inline gauge during service to confirm stable outlet pressure after the filter and regulator.
Leak Testing And Safety Around Gas Filters
After installing or servicing a gas filter, apply leak-detection spray or a soapy solution to every joint. Bubbles indicate a leak that must be corrected before use. Maintain ventilation in the locker so heavier-than-air gas can escape at floor level.
Separation From Heat And Electrics
Route lines away from hot flues and electrical wiring. Protect pass-throughs with grommets and support pipe with cushioned clips to prevent vibration wear.
Winter And Storage Tips
Before long storage, check the element and seals, then perform a quick leak test at the start of the next season. Store spare pads cool, dry and out of sunlight.
Accessories To Pair With Gas Filters
Carry spare pads, O-rings, a regulator gasket and leak-detection spray. A compact spares kit keeps your gas filters serviceable and your system dependable wherever you camp.
Troubleshooting Checklist
Confirm bottle level, inspect the filter, verify 30 mbar at the appliance, then clean jets if flames remain uneven. Work methodically and retest after each step.
