What Appion does

Appion, Inc. is a private US manufacturer of professional HVAC/R (heating, ventilation, air conditioning, and refrigeration) tools headquartered in Englewood, Colorado. The company designs, manufactures, and sells equipment used by HVAC/R technicians for refrigerant recovery, AC/R system evacuation, digital measurement, and related service operations across four product lines: refrigerant recovery machines (G5TWIN, G1SINGLE), vacuum pumps (TEZ6, TEZ8), digital measurement tools (WS130/WS260 precision scales, PTC900 compound gauge, RHT100 humidity/temperature gauge), and service tools including Speed-Y fittings, MegaFlow hoses, core control tools, and valve core removal tools. Appion also operates the Appion Central mobile application for Bluetooth-enabled digital measurement tools, supporting remote monitoring, data logging, and custom alarm configuration with up to 1,000 ft wireless range.

The product portfolio is built on multiple registered US and international patents covering recovery machine architectures, vacuum pump sealing technology, and digital gauge designs (e.g., US7878081, US8939042, US10036371 on recovery machines; US7674096, US8651828, US9080569 on vacuum pumps; AU2005289911, JP5107042, WO2006036598 internationally). Notable proprietary features include the TEZOM cartridge system, which enables oil changes on the TEZ8 vacuum pump without breaking vacuum, and MegaFlow high-speed hoses vacuum-rated to 20 microns with pressure tolerance for refrigerants such as R410A. Speed-Y fittings carry 800 PSI working pressure and 4,000 PSI burst pressure ratings. The G5TWIN recovery machine has been positioned as an industry staple for over twenty years, anchoring Appion's brand recognition in the HVAC/R professional segment.

Appion generates revenue primarily through hardware sales to authorized local distributors across the United States, supplemented by direct-to-customer e-commerce (appiontools.com) for support parts, repair kits, and accessories, plus factory repair services performed by Appion Factory Trained Service personnel. Pricing follows a one-time purchase model; flagship equipment is sold exclusively through distributors at undisclosed prices, while support parts are listed with explicit unit pricing (e.g., TEZ8 External Maintenance Kit at $124.99; MegaFlow hose gasket kits at $27.99-$33.99; TEZ8 Debris Tube Door at $22.99). Shipping is restricted to US addresses in the 50 states only, with free 2-day delivery on most orders. Appion employs 11-50 staff and operates with no disclosed external funding, parent company, or institutional ownership.
