Estimating the term…
A gas-liquid rotating coalescer includes first and second sets of one or more detent surfaces on a rotary drive member and a driven annular rotating coalescing filter element which engagingly interact in interlocking mating keyed relation to effect rotation of the coalescing filter element by the rotary drive member. Designated operation of the coalescer requires that the coalescing filter element include the second set of detent surfaces. A coalescing filter element missing the second set of detent surfaces will not effect the noted designated operation.
A gas-liquid rotating coalescer separating liquid from a gas-liquid mixture, comprising a coalescing filter assembly comprising a housing having an inlet receiving said gas-liquid mixture, a gas outlet discharging separated gas, and a drain outlet discharging separated liquid, an annular rotating coalescing filter element in said housing, a rotary drive member, a first set of one or more detent surfaces on said rotary drive member, a second set of one or more detent surfaces on said coalescing filter element, said second set of one or more detent surfaces engagingly interacting with said first set of one or more detent surfaces in interlocking mating keyed relation to effect rotation of said coalescing filter element by said rotary drive member.
A coalescing filter element for a gas-liquid rotating coalescer separating liquid from a gas-liquid mixture in a coalescing filter assembly having a housing having an inlet receiving said gas-liquid mixture, a gas outlet discharging separated gas, and a drain outlet discharging separated liquid, said assembly including a rotary drive member having a first set of one or more detent surfaces, said replacement coalescing filter element comprising an annular rotating coalescing filter element having a second set of one or more detent surfaces engagingly interacting with said first set of one or more detent surfaces in interlocking mating keyed relation to effect rotation of said coalescing filter element by said rotary drive member, wherein designated operation of said coalescer including designated rotation of said coalescing filter element requires said second set of one or more detent surfaces, including said engaged interaction with said first set of one or more detent surfaces in said interlocking mating keyed relation, whereby a coalescing filter element missing said second set of one or more detent surfaces will not effect said designated operation.
