Air conditioning
The Air Conditioning category covers A/C system parts for vehicles and machine cabs. You will find A/C compressors, condensers, evaporators, expansion valves, receiver-dryers and hoses/fittings. A working A/C system is not just about comfort — in construction and agricultural machine cabs it prevents operator fatigue and improves work safety.
The range at Filtry.org focuses on truck and off-road machine cab A/C, where the system operates under extreme conditions — high ambient temperatures, dust and vibration.
Frequently asked questions
How often should vehicle/machine A/C be serviced?
Every 1-2 years a leak check and refrigerant level inspection is recommended. A 10-15% annual refrigerant loss is normal. Replace the cabin filter (internal air dryer) every 15,000-20,000 km or every season.
What symptoms indicate a faulty A/C compressor?
No cooling, noisy compressor operation, cycling on and off, compressor-oil leaks at fittings. If the compressor seizes — belt failure or electromagnetic clutch disengagement.
Must the receiver-dryer be replaced with every A/C repair?
Yes — the dryer absorbs moisture from the refrigerant and becomes saturated with atmospheric moisture once the system is opened. Refitting an old dryer in a repaired system risks expansion-valve freeze-up and internal component corrosion.
