Air Conditioning Receiver Drier / Desiccator
Maintain the performance and reliability of your Porsche 928
air conditioning system with this OE Match Air Conditioning Receiver Drier /
Desiccator. Designed specifically for Porsche 928 models from 1978 to 1986,
this essential A/C component helps remove moisture and contaminants from the
refrigerant circuit, protecting critical system components while ensuring
efficient cooling performance.
Fits:
- Porsche 928 4.5L 1978-82
- Porsche 928S 4.7L 1981-83
- Porsche 928S2 4.7L 1984-86
Diagram ref no 28
The receiver drier plays a vital role in every automotive air conditioning system. It acts as both a refrigerant reservoir and a filtration unit, containing a desiccant material that absorbs moisture before it can damage expensive components such as the compressor, expansion valve and evaporator.
Manufactured to OE Match standards, this replacement receiver drier provides the correct fit, performance and reliability required for air conditioning repairs, system overhauls and preventative maintenance.
What Does an Air Conditioning Receiver Drier Do?
The receiver drier is installed within the high-pressure side of the air conditioning system.
Its primary functions include:
- Removing moisture from the refrigerant
- Filtering contaminants and debris
- Protecting the A/C compressor
- Supporting efficient refrigerant flow
- Preventing internal corrosion
- Acting as a refrigerant storage reservoir
- Improving air conditioning performance
Without an effective receiver drier, moisture can circulate through the system and cause significant damage.
Why Do Receiver Driers Fail?
Receiver driers contain desiccant material that has a finite lifespan.
Common causes of failure include:
- Moisture saturation
- Age-related deterioration
- Long-term refrigerant exposure
- Internal desiccant breakdown
- System contamination
- Air conditioning system leaks
- Extended periods of inactivity
- Previous compressor failures
Once saturated, the desiccant can no longer absorb moisture effectively, reducing system efficiency and increasing the risk of component damage.
Symptoms of a Failing Receiver Drier
Common warning signs include:
- Reduced air conditioning performance
- Weak cooling output
- Moisture contamination within the system
- Corrosion inside A/C components
- Expansion valve problems
- Compressor wear
- Refrigerant flow restrictions
- Air conditioning system repairs following leaks
In many cases, receiver drier deterioration occurs gradually and may not be immediately obvious until cooling performance begins to suffer.
When Should the Receiver Drier Be Replaced?
Replacement is strongly recommended when:
- Replacing the A/C compressor
- Opening the refrigerant system
- Repairing refrigerant leaks
- Performing a full A/C service
- Restoring a Porsche 928
- The receiver drier is several years old
- Contamination is suspected within the system
- Refrigerant performance has declined
Most air conditioning specialists replace the receiver drier whenever the system is opened to atmosphere.
Why Replacement Matters
Replacing the receiver drier helps protect the entire air conditioning system.
Benefits include:
- Improved cooling performance
- Moisture removal from refrigerant
- Protection of the compressor
- Reduced risk of corrosion
- Improved refrigerant efficiency
- Extended component life
- Improved reliability
- Lower long-term maintenance costs
A new receiver drier is one of the most cost-effective ways to protect expensive A/C components.
