The AREX series is a rotary valve for dust collectors that pursues lower cost, space saving, and lighter weight than general-purpose rotary valves. A square flange is used to match the shape of many dust collector outlets, and a urethane rubber rotor is used to enhance its air sealing property. The rotor has a structure that makes it easy to remove and assemble, so it can be used for a long time with simple maintenance. Metal rotors can also be manufactured according to your request.
