perfect roundness Slot tube 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.

perfect roundness Slot Tube 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.

Standard constructions of slot tubes (special constructions are possible on request)
The designation of a slot tube describes its construction as follows:
surface wire / support wire x number of support wires.
Example: 12S/Q25 x 8
This means that the profile wire is 12S. The support wire is Q25 and there are 8 support wires, equally spaced over 360°.
Slot tubes with dimensions and/or tolerances other than those described below, are available on request.

Reversed profile
Normal construction of slot tubes allows for flow out to in filtration. However, flow-in -to-out constructions are also possible.
This construction can also be used when the slot tube is used as support tube for another filter medium, so that only the wedge is in contact with the medium to increase the open area.
Variable slot opening
For special purposes variable slot openings are possible for all diameters.
Continuous cylinders
By using a lot of support profiles, an axial slot can be obtained.
These filter elements are called continuous cylinders.
Support tubes
See support tubes.
Standard finish
grinding of end surfaces
removal of loose profile ends
degreasing and pickling
Optional finish
fastening of loose profile ends
removal of burs of profile ends
post machining for tighter tolerances
