Perforated Filter Screen
Product Description
Perforated funnel Perforated funnel are popularly used in filter products as support tubing, and sometimes it is used directly as filter tubes and cylinders for certain industries.
We supply perforated tubes to support the filter media in making of various filter elements. Using of perforated metal adds more strength and pressure resistance in filter flow.
