It is a major part of the car's air conditioning system (A/C System), colloquially called:
- Freon dryer
- Metal air conditioner filter
- Freon box

🔄 Its role in the air conditioning system:
- After the Freon is compressed in the compressor , it passes to the radiator .
- From there, it enters the Freon box or radiator filter (Receiver Drier) where:
- Remove moisture (which may cause freezing inside the valves)
- Purifying Freon from solid particles
- The pure Freon is then passed to the refrigerator expansion valve and then to the refrigerator (evaporator) to cool the air entering the cabin.
❄️ Why is it necessary to have a Freon box or filter?
- Humidity inside the freon circuit is considered the number one enemy of the air conditioner.
- If not removed, it may lead to:
- Ice formation inside pipes
- internal corrosion in pipes
- Low cooling efficiency
- microvalve obstruction
