Or-Tec Blue Whale Micro Bar Screen

The world's only super fine mechanical bar screen with openings down to 1mm

The Or-Tec Blue Whale Micro Bar Screen is a superfine mechanical bar screen with openings as small as 1mm (0.03"). The Micro Bar Screen removes the vast majority of hairs, rags and stringy material which pass through screens with larger openings. These smaller openings help to prevent matting or ragging forming on items such as pumps, mechanical seals, diffusers and rotating equipment. Maintenance on these items is reduced to practically zero as matting and ragging no longer builds up. Read more

The Micro Bar Screen and Compactor Washer have worked very well for us. We are very happy with its performance and its results...and I am a skeptic.
