two types slot filtration

What are slot tubes?

Slot tubes are composed of a surface profile that is spirally wrapped around axial support profiles and attached to each other by resistance welding.These filter elements have the unique advantages 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.

Filter cycle:During the filter cycle,the solids are deposited on the smooth surface.This cake acts as an extra filter for finer particles.The fines that slip through do not get stuck in the conical slots.

Backwash cycle:By reversing the flow,the cake and dirt are removed from the filter surface.

The Specification of the products

Special features

Inverted profiles

Inverted profile,for filtration in to out with support profiles at the inside,is possible for most profile combinations.

Variable slot opening is possible for slot tubes with outside diameter up to 914 mm.

Continuous cylinders

By using a lot of support profiles ,an axial slot can be obtained.These filters elements are called continuous cylinders.The minimum slot width is 0.1mm.

Reinforced slot tubes

Reinforcing the slot tubes is possible through:

-more or stronger support profiles;

-reinforcement spiral;

-reinforcement cross;

-perforated reinforcement tube,used as distributor of the fluid over the slot tube
