ComVac ASIA (Shanghai International Compressor and Equipment Exhibition) is an annual trade fair for compressed air and vacuum technology. It draws compressor and vacuum equipment makers, component and post-processing suppliers and industrial buyers. The display covers compressed air technology — air, process and special compressors, compressor parts and components, post-processing equipment, and lubricants and auxiliary equipment — alongside vacuum technology, from vacuum pumps, valves and accessories through measuring and calibration instruments, gauges and leak detectors to vacuum application equipment and vacuum materials.

The show runs alongside PTC ASIA, CeMAT ASIA and ePackTech each autumn as part of a large industrial equipment cluster in Shanghai, and hosts a series of industry forums and technical seminars of its own.
