It pays to flush
Professional service on automotive A/C systems naturally also includes flushing the system to clear away aggressive substances and contaminants from the refrigerant circuit. Flushing protects all parts of the air conditioner from damage, especially the compressor being its core component.
You will never get a hundred per cent clean refrigerant circuit, this because of the parallel flow evaporator technology commonly used these days. We strictly recommend you to add a chip filter to the suction line when you flush the system. This will protect the compressor and is especially advisable when you’ve replaced the compressor, as it will keep the remaining particles away from the newly fitted unit.
Important note: The chip filter (Ref. No. 8880700246) should be replaced after every flushing process (for each vehicle)!
