A filter unit 100 comprises a filter plate 102 having first and second sides and a collar flange 104 having first and second sides, attached to one side of the filter plate. An end plate 114 has first and second sides and a number (10-20) of bars 106 each having a first end and a second end. The first end of each bar is attached to the second side of the collar flange and the second end of each bar is attached to the first side of the end plate, in an essentially circular pattern having a circumference of 250-600 mm. The filter unit also comprises a filter element 112 made from fabric and forming a tube having a circumference of 700-2000 mm, and arranged in contact with the bars essentially equidistantly along the circumference of the filter element. The filter unit may be used to filter air and may advantageously provide increased filtering throughput and efficient cleaning of the filter element by dislodging residue with a force of air. |
