Self cleaning brush filter vessel by gravity filter down to 50
micron particle removal
The brush type self cleaning filter is mainly used in the fluid
which contains more gravity impurities in liquid to be filterred.
It's gravity filter.
Automatic self-cleaning filter is a kind of filter which is
suitable for bad environment. It's with 3500 micron- 50 micron mesh
and 8”-36”pipeline diameter for different using requirements. The
cleaning process is started by a differential pressure switch which
is monitoring the differential pressure of inlet and outlet,
normally the pre-set value is 0.5bar (7psi).
Suitable for filters with DN25~DN900 pipeline to choose from. With
advantages of continuously fluid flow, safety operation, simple
maintenance, this kind of filter is widely used in all industries.
When the differential pressure of inlet and outlet reaches the
pre-set value, the filter will start the cleaning process. The
whole self-cleaning process includes two steps: 1. Turn on the
drain valve which is on the filter top cover. 2. Two stainless
steel brushes inside the filter mesh start to rotate which are
driven by motor. The impurities captured by filter mesh are brushed
by steel brush and discharged from drain outlet. The whole cleaning
process takes about 15-60 seconds. During this time, the filtration
system doesn’t interrupt the water supply and the whole operation
process is controlled by a control box.
- Uninterrupted water supply: the water consumption of cleaning is
very few, which is less than 5% of the total flow. The cleaning
time is about 2~15 seconds. When it is cleaning and discharging,
water supply is uninterrupted.
- High filtering accuracy: filtering accuracy can reach up to 20μm
and there are all kinds of accuracy of filtering screen can be
- Large filtering area: effective filtering area of standard screen
is 7-40 times of inlet area.
- Reliable cleaning: a variety of control modes can be selected, such
as manual, differential pressure, time, PLC control, etc.
- Simple and economical installation: varied structure forms, which
are suitable for all kinds of site situation installation, without
affecting the operating effect.
