Conical strainer can effectively filter out the particles in the pipelines and keep the machines work normal. It can also be used to protect compressors, pumps, turbines and magnetic valves. Conical strainer has high strength, good rigidity and high filtration efficiency. It's stable performance can ensure the efficiency of production equipment and protect the pumps, valves and other devices.

Cone strainer has a simple structure and a small volume. It is suitable for the places where space restrictions are needed. This type of filter element is easy to install, remove and clean. It is extensively used in the chemistry, petroleum, pharmacy, water treatment and environmental protection field. Conical strainers can be made from various materials, such as sintered wire mesh, stainless steel wire, copper and other materials.
