The present invention pertains to an environmentally safe, lightweight, portable, user-friendly, self-contained, low-maintenance, refrigerant recycling, purification, and storage system capable of removing refrigerants from refrigeration units for subsequent cleaning of acids and impurities such that the refrigerant will be easily recovered and reused instead of being carelessly released into the atmosphere. In addition to recovery and reuse, the present invention can be used to then recharge the refrigeration system with clean refrigerant or function as a leak tester, or remove obstructions from blocked lines or function as a vacuum pump. Refrigerant is evacuated by placing the lightweight device beside the unit to be repaired and then evacuating the refrigerant through a disposable filter and into a storage tank. The entire operation is completed at a relatively low pressure and because of the lightweight, can be accomplished on-site thereby obviating the need to remove the device. |
