Depending on your car’s air conditioning system, the drier will either be referred to as a receiver drier or an accumulator/drier. The Drier is located on the liquid hose between the A/C condenser and the evaporator system’s expansion valve. Its primary function is to act as a filter and secondary function to store excess refrigerant. The Drier keeps out all the harmful debris from clogging the a/c systems expansion valve and dries out any moisture that can contaminate or internally freeze your AC system. Be certain to replace your receiver/ drier anytime you perform maintenance on your air conditioning. Opening up the AC system to the environment will allow moisture in the air to enter your A/C system quickly and render your receiver /drier useless. Restomod Air ’s aftermarket A/C Driers have a threaded port on them to allow the insertion of a safety switch or trinary switch for compressor function.
