※ Introduction
Filters developed by our company possess the following feature: compact structure, excellent capability of filtering, wide application, easy maintenance, low price etc. Target medium of the product are as following:
Low corrosive material generated by chemical industry and petrochemical industry, such as: water, oil, ammonia and hydrocarbon etc.
Corrosive material generated by petrochemical industry, such as: liquid methane, liquid ammonia, liquid oxygen, and all kinds of refrigerating fluid.
In addition to functions of common filter, the newly developed filter products of our company can provide information of changing or cleaning filter screens and distant light warning.

5, Hand Brush Filter
※ Introduction
Hand Brush Filter is a kind with simplicity and efficiency. When impurity accumulated on cone-shaped filter screen, there will be pressure difference between inlet and outlet, and there will be cleaning request when the difference reaches certain level. There is no need for people to open any part of the device when the process goes on, and the only thing to do is to open the valve and turn the handle for 3-4 circles. And the result will be beyond expectation.
※ Features
Linear structure is applied. Delicate design is used for space save;
Filter screen of high precision and high strength is applied.
Cone-shaped. Precision reaches 100～3000 micrometer;
Easy cleaning: stainless brush is used;
No cutoff when reverse wash goes on;
Water for reverse wash is extremely little, which is no more than 1% of the total flow.
