Oil Line Filter housing, duplex basket filter Unit Introduction:
The online duplex filter is composed of two single bowl filters and a 2-position 3-way directional valve. It is simple in structure and easy to use. There is by-pass valve and a contamination indicator in it for protecting the hydraulic system safety.
Duplex filter is widely used in the hydraulic systems of heavy duty, mining and metallurgical machines.
The feature of duplex oil strainer allows for continuous operation when changing elements due to clogging caused by contaminants. After opening the balance valve and turning the directional valve, the other filter begins to work, thus a clogged element should be changed in time.
These series of duplex basket strainer have a high flow range from 1300 l/min to 15000 l/min
Usage
This stainless steel type duplex filter is used to filter various solids or colloids in the liquids such as cooking oil,fruit juice,sirup,milk and beverages etc. Two filters can be changed over.the filter screen can be cleaned without stopping.
Descriptions
1.Duplex filter is used in return line, it can remove all the contaminants from the
hydraulic system, and allow the clean oil flow back to the tank.
2.The element of this series is made of glass fiber, it has high efficiency and filtration ,
large dirt capacity and lower initial pressure drop.
3. There is a bypass valve and a contamination indicator.
4. The indicator will act when the pressure drop across filter element attains 0.35 M pa,
the element should be changed at this time.
5.If the system can not be stopped or nobody replaces the element, the bypass valve
will open to protect the hydraulic system safety.
6. The feature of this filter allows continous operation even during element is changed for which is clogged by contaminants,After opening the balance valve and then turn the directional valve,the other filter begins to work,the clogged element should be changed in time.
This duplex filter is widly used in the hydraulic system of heavy duty mining and metallergical machines.
