Slot tubes are welded structures with the support profiles being rods in the axial direction of the tube and surface profiles spirally wound around the support profiles.
Slot Tubes are manufactured directly on a machine. They have the unique advantage of very accurate, narrow slot openings and perfect roundness all in one. Slot tubes can be provided with the necessary end pieces for attachments and/or reinforcements.
Rotary Drum Screens are used to mechanically separate liquids from solid particles. Gap Technology offer a wide range of Rotary Drum screens and Rotary Wedge Wire Screens / Trommel Screens for industrial waste water screening applications to our large and varied customer base throughout the United Kingdom and across Europe.
The wedge wire bar rotary drum screen provide more sufficient opening than the perforated metal baskets. It is stronger and can bear heavy loading pressure than the woven mesh filter baskets. The wedge wire basket can work with both benefits of the perforated and woven mesh filter elements and avoid the shortcomings. It is stronger, has more aperture and pressure differential levels can be achieved by variety of the slotting. Also it is economic.
