The API® RW automatic Rotating rake bar screen consist of a frame composed of a press-formed sheet which incorporates a fixed bar screen to ensure maximum rigidity. The construction generally uses structural carbon steel in grade S235 – S275 – S355 with hot galvanising protective treatment in accordance with EN 1461 or painted with thixotropic epoxy product suitable for immersion, but is also available entirely in AISI 304 or AISI 316 stainless steel. The space between the bars can be varied to obtain a fine or coarse grill according to the plant's requirements. The grill does not require modifications to existing masonry work and is easy to fit using mechanical anchor bolts.
