POLYPROPYLENE WOUNDED CARTRIDGES
COTTON WOUNDED CARTRIDGES

(Cotton wounded cartridges with inner core in stainless steel 304)
Pressure filter cartridges are particular structures which are got by winding of the thread on a stiff central body (core).
The stress and twisting received by the thread cause the gradual selectivity which is prograssive from the external surface to the core.
The filtration grows in a spiral sense and allows a growing retention in depth.
The absolute absence of binders allows a good chemical compatibility with every treated fluids and therefore offers a high versatility of use.
