Bag filters have a filtering surface with reduced
dimensions and they are used as safety filters supporting other main filters.
They consist of a vertical cylindric body which
contains a basket.
Inside the basket there is a filter bag which can have
various characteristics and can be provided with a large variety of fabrics and
mesh.
The design of these filters can also predict from one
up to 16 bags assembled in parallel within the same container to increase the
filtering surface. On the contrary they can be assembled in pairs using a
system of pipes and valves, in order to continue the filtration process during
the change of a full bag.
The materials used for the
realization can be different: carbon steel, stainless steel and special
austenitic ferritic steels such as Duplex, Super Duplex, Nickel alloys and
Titanium Gr. 2, considering also the conditions in which the filters operate.
All filters can be supplied
according to the most common international standards: ASME Sec. VIII, EN13445,
BS BS500, AD2000 and can be tested according to PED2014 / 68 / EC requirements,
supplied with CE mark and USTAMP as needed.
We
can design this type of filter for many applications but the principal one is
the removal of liquid particles.
The
filter elements can be realized in all type of metallic materials.
Type
of liquids: industrial, water, paintings.
