A complete refrigerant recovery system is essential for safely reclaiming refrigerants from air conditioning and refrigeration systems. The critical components of such a system include a recovery machine, which is designed to extract refrigerant from the system and compress it for storage, and a storage tank, which securely holds the recovered refrigerant until it can be recycled or properly disposed of.

It’s also important to have the necessary hoses and fittings to connect the recovery machine to the air conditioning system. These ensure that the refrigerant can be transferred without leaks or contamination. The hoses must be rated for the pressures involved in refrigerant recovery, and the fittings must match the connections on both the recovery machine and the unit being serviced.

While other options might include some relevant components, they do not encompass all the essential items necessary for a complete refrigerant recovery process. For instance, using a filter dryer or expansion valve might not be directly part of the recovery process itself. Similarly, an air handler and compressor are components found in HVAC systems but are not involved in the recovery of refrigerant. A vacuum pump, while useful for other HVAC maintenance tasks, does not serve the primary function of a recovery system. Therefore, having the recovery machine, storage tank, and necessary hoses and fittings together completes
