Appion is Star Performance. With applied innovation, we never stop challenging ourselves to develop smaller, lighter, easier, better and less expensive ways to help HVAC/R technicians perform their everyday tasks. Our products are made from decades of manufacturing experience, and always with the needs of the HVAC/R technician in mind.


Appion Inc, based in Colorado, entered the HVAC/R market with the G5Twin. The G5 is the fastest, and most versatile refrigerant recovery unit ever available in this market all while weighing in at a mere 24 pounds. The innovation continued with the release of the TEZ8cfm and the SpeedSystem, representing the first major advancement in vacuum pump technology in over 40 years. Appion has continued to innovate the market with products such as the ION PT pressure/temperature Gauges (the PT500 and PT800), the Vacuum-Rated MegaFlow™ Valve Core Removal Tools (both 1/4" and 5/16”), the AV760 Full Range Micron Gauge, and the G1Single Residential Recovery machine.


With each of these products, Appion has delivered new ways to improve the results of everyday HVAC/R service, maintenance, and installation. We’re continuing to improve so we can help give technicians every competitive advantage possible.


With products designed for the best performance and ease of maintenance, Appion's commitment is to serve our customers well by providing the most innovative, user-friendly, and durable tools/equipment the HVAC/R market has to offer.


Innovative equipment design and manufacturing is just the start. With the recent developments involved with the ION HVAC/R App™, technicians are able to utilize technology with our products to be more organized, efficient, and strategic with their work days. Additionally, Appion provides hassle-free technical and troubleshooting support for the lifetime of every product.


Appion stands behind the commitment to customer satisfaction that goes beyond expectations!
