Air Compressors & Industrial Equipment
Used Atlas Copco GA 18: Sell or Buy at Auction
Atlas Copco is a Swedish industrial equipment manufacturer, one of the world's largest compressor manufacturers alongside its vacuum, power tools, and industrial technique divisions. Atlas Copco rotary screw compressors are a standard in industrial facilities worldwide, known for energy efficiency and reliability.
The Atlas Copco GA 18 is an oil-injected rotary screw air compressor built around an 18 kW motor, about 24 hp, sized to hold steady shop pressure for a floor running several pneumatic tools or a small automated line. In the GA family it sits a step above the 15 kW GA 15 and below the larger GA 22, GA 30, and GA 37 units that feed full plants, which makes it a common mid-capacity pick for a shop that has outgrown a single tank-mounted compressor but does not need plant-wide air. Free air delivery lands roughly in the 100 cfm class at standard shop pressure and falls as the unit is configured for higher pressure, so it is worth checking a listing's pressure rating. Configuration matters too: most GA 18 packages are air-cooled and run Atlas Copco's Elektronikon controller, the line shipped in a fixed-speed base version alongside variable-speed (VSD) siblings, and Full Feature (FF) units carry an integrated refrigerant dryer. At auction the GA 18 draws manufacturing plants, automotive and machine shops, and food and beverage producers looking to add or replace mid-capacity air without new-equipment lead times, and Atlas Copco's global parts and service network keeps demand for used units steady. Units with documented service history, lower running hours, and a sound airend pull the strongest bids, since compressor buyers weigh maintenance records heavily before committing. KD Auctions markets every GA 18 listing to its 500,000+ industry contacts, pairing the brand's resale pull with targeted outreach to shops and plants actively sourcing compressed air capacity.

What is a used Atlas Copco GA 18 worth at auction?
It depends on the specifics: age, running hours, airend and package condition, whether the unit is fixed-speed or VSD, and whether it includes an integrated dryer or other accessories, so we do not publish blanket price figures. KD Auctions provides a free AMEA-accredited, USPAP-compliant appraisal that documents both orderly liquidation value (OLV) and forced liquidation value (FLV) for your exact unit, giving you a defensible number before you decide whether to sell.
How does the GA 18 compare to other Atlas Copco GA compressors, and how do I sell one?
The GA 18 sits in the mid-size tier of the GA line, a step above the 15 kW GA 15 and below larger plant units like the GA 22, GA 30, and GA 37, so it tends to draw buyers who need reliable air for several pneumatic tools or a single automated line rather than a full production floor. To sell a GA 18, on its own or alongside other shop equipment, call KD Auctions at 480.455.3910: commission is tailored to the engagement and quoted upfront, most sellers pay nothing out of pocket, and managed auctions run 6 to 10 weeks from engagement to payout, with onsite dispatch scheduled within 48 to 72 hours of sign-off.
