Hi everyone, and welcome to the MACS Podcast. We're glad you're here! ~~~~ Welcome to the ninth episode of the MACS Podcast! Hosted by Steve Schaeber, MACS technical editor & manager of service training, and Peter Coll, MACS president & coo. MACS Podcast Episode 9: Dave Hobbs, Delphi Technologies (hosted by Peter Coll) In our ninth episode, Peter sits down with long time MACS member and annual training event instructor, DAVE HOBBS from Delphi Technology. After all these years of working with MACS, this was the first time that Dave visited the MACS office! Join Peter and Dave as they discuss topics important to our industry, such as the Right to Repair, service information, scan tools, training, safety, air conditioning refrigerant and NASTF. Keywords: EPA: US Environmental Protection Agency SAE: Society of Automotive Engineers SAE International HFTC6: human factors technical committee CDPC: cabin disinfection practices committee ~~~ For more than 30 years, shops and technicians who service mobile A/C systems in the United States have been using EPA-certified RRR machines (recover, recycle and recharge equipment) to properly recover refrigerants from vehicle A/C systems, rather than release the refrigerant to the atmosphere. These machines are required to be used under the US Clean Air Act Amendments of 1990, and have played a major role in protecting the Ozone Layer. They have also helped to avoid countless emissions of HFCs and other CO2 and CO2-equivalent emissions from the mobile sector, by allowing shops to efficiently and effectively recover and recycle refrigerants (such as R-12, CFC-12, R-134a, HFC-134a and R-1234yf, HFO-1234yf) on-site at the shop level. "Recovery" is a process which is performed through the use of either a Recovery-Only machine (such as an SAE J2851 machine) or through the use of an RRR machine (such as an SAE J2788, J2843 or J3030 machine). The "recovery" procedure simply removes refrigerant from an A/C system and puts it into a "recovery cylinder" for storage. "Recycling" is a process which is performed through the use of an RRR machine (such as an SAE J2788, J2843 or J3030 machine), whereby refrigerant is "recycled" in the machine using filters, for eventual re-use in a mobile A/C system. MACS supports RECYCLING refrigerant on-site by certified technicians, at the shop level, through the use of certified RRR equipment which meets SAE Standards. Refrigerant recycling on-site provides for the lowest environmental impact, and the lowest cost for the shop and the consumer. ~~~~ Are you a member of MACS?
