Witches Hats
Witches’ hat filters can be composed of layers of wire cloth to
create a filter material with higher strength and rigidity. The
multilayer meshes form an ideal uniform filtration structure. The
material and structure maximise the flow area, effectively reducing
resistance and ensuring reliable operation. Witches’ hat strainers
can be used for softening, desalination, water filtration and water
pre-treatment systems, as well as less demanding water supply
and oil fine filtration equipment. They are primarily used to provide
a filtering layer that removes solids suspended in water, oil and
adhesive resin. The filters can be manufactured for a wide variety
of applications. In 316 stainless steel, they can be made with a
pore size of as little as 1 micron, using a single mesh or a number
of meshes to achieve the required micron rating.
Quick Release Filters
The Quick Release Inline Filter is a very popular filter and has a
widespread usage in applications within industrial sectors such as
Food, Oil & Gas, Power Generation, Chemical and Marine amongst
many others. Available in many different fittings makes this
arrangement highly desirable as it can be made to fit straight into
your existing application with ease. Providing some flexibility has
been allowed upon installation, it is very easy to remove the internal
filter disc for cleaning or replacement. A quick release clamp allows
separation of the two halves with little effort. You have a choice to
use the internal filter disc as provided or to combine it with mesh to
achieve different levels of the filtration as required.
