Neptune Mixer says its Series F industrial mixers can be inserted into the 2-in. (51-mm) bung of standard 55-gallon steel drums and then clamped to the drum’s lip, providing easy, economical and efficient mixing of solutions. According to Neptune, the key to the design of the Series F mixers is the folding propeller. When closed, the propeller can be inserted into the bung; once inserted, the propeller, which is constructed of 316 stainless steel, opens to a diameter of 3-3/4 in. (95.25 mm), and mixing operations can be performed at speeds up to 1,750 rpm. Series F mixers are available in four Totally Enclosed Fan-Cooled (TEFC) models—F-1.0, F-2.0, F-3.0 and F-3.2—that feature power ratings from 1/4 to 1/2 hp (0.18-0.37 kW), as well as a 1/2-hp explosion-proof model (F3.1) that satisfies Class 1, Group D (EP) requirements. An F-4.0 model features an air motor and is available in 1/4- and 1/2-hp sizes.
