How does this receiver drier protect my APU's air conditioning system?

The receiver drier removes moisture and filters contaminants from the refrigerant, helping prevent valve icing and internal corrosion. Its stainless steel filter media captures metal particles and other debris that can damage the expansion valve and compressor.

• Moisture absorption reduces the risk of freeze-ups in expansion valves.
• Stainless steel filtration traps metal shavings and particulates.
• Switch feature allows integration with diagnostic or system-control circuits.
