Model ACS "POSI-CLEAN" Element

ACS "POSI-CLEAN" Element

The Concord Screen Inc. Model ACS "POSI-CLEAN" element is cylindrical, made of reverse formed and resistance welded wedgewires. Flow during straining is from the inside to the outside. Flow direction for backwashing, however, is opposite. The basket is a fabricated cage assembly that consists of a top, bottom and middle spacer ring that are fit and welded to the vertical spacer rods. ZThe screen elements are constructed for easy replacement; they are bolted around the cage assembly in equal segments.

The "POSI-CLEAN" straining elements manufactured by Concord are available in reverse wrapped configuration to 0.001".

Concord "POSI-CLEAN" straining elements are designed to give maximum open area and to deliver top performance in any straining application.

ACS Control Systems

Every ACS strainer is shipped completely assembled, ready to operate. A single 1/3 H.P. motor drives the backwash mechanism of the largest strainer size. The automatic backwash controls (if required) actuate the backwash cycle.

Concord automatic controls are engineered and designed to allow for optimal performance and ease of operation. They are factory set and field adjustabnle so as to provide for a minimal loss of backwash liquid and provide total cleaning of the "POSI-CLEAN" element.

Application and Industrial Uses

ACS strainers are designed for removal of suspended particulate from all types of liquids, used in practically all industries for quenching, lubrication, spraying, cooling, descaling, pump, valve, heat exchanger and spray nozzle protection. Liquids filtered include well take, river, cooling tower or sea (salt water) to white water, black liquor (pulp and paper mills), chemicals, acids, sewage and lubricating oils.
