Paint shakers are electric- or pneumatic-powered machines designed to automatically and thoroughly mix paint by aggressively shaking paint in cans or buckets for a set amount of time. More efficient than hand mixing, mixing attachments, and agitators, paint shakers can rapidly mix high volumes of paint for paint store customers or industrial applications. Paint shakers have varying designs for different applications. Countertop paint shakers with single or double arms can mix one or two cans of paint at once. Paint shakers with a gyroscopic mixing motion rapidly turn paint buckets or cans in every direction instead of shaking them. Quiet operation paint shakers are ideal for mixing paint inside stores. Explosion-proof paint shakers are used to mix paint in hazardous locations, such as environments with welding operations or open flames.
