These metal structures
used with Filter Bags to help the suction and cleaning systems
when they are based on injecting compressed air. Filter Pure
Venturis are manufactured in spun or cast material. The Cages for Filter Bags are produced by Filter Pure to
order, and according to the fabric used to
manufacture the Filter Bags. This information will determine the number of bars the cages
as Polyester, Acrylic or Meta-Aramid work with cages with 10 to
12 wires. With other fabrics, such as Teflon
or Fibre Glass, the distance between bars should not be more
than 25 mm, and therefore (depending always on
the required diameter), in some cases the cages have 20 wires.
To improve resistance to the
oxidations often suffered by Epoxy painted Iron Cages or similar
cages, even before they are
installed in the Filter Bag, there is a treatment called Bezinal,
where resistance to corrosion is two or three times higher
than wires galvanized with a triple layer of zinc. In addition,
it is a ductile and uniform coating with an excellent degree
of mechanical deformation, and is an excellent conductor of
static electricity as it contains aluminium.
and Cages are designed and manufactured according to the needs
of the installation or to the measurements provided
by the customer.
Anti-corrosive treatments to prolong the life of the
All joints are welded to prevent tearing the fabrics.
