Precision filter (also known as security filter), the shell of the cylinder is generally made of stainless steel, and the interior uses tubular filter elements such as PP melt-blown, wire-fired, folded, titanium filter, activated carbon filter, etc. as filter elements, according to different filter media and The design process selects different filter elements to meet the requirements of effluent water quality. This kind of filter is used for solid-liquid separation of various suspensions, high environmental requirements, and high filtration precision for liquid medicine filtration. It has a wide range of applications and is suitable for industrial fields such as medicine, food, chemical industry, environmental protection, and water treatment.

Instructions for installation and use of protective filters:

1. Thoroughly clean the filter housing.

2. The inlet and outlet of the net outer wall are connected to the pipeline of the filtration system. When connecting, pay attention to the direction to ensure that the filter element is in the state of water inlet from the outside and water outlet from the inside.

3. Open the plastic bag at the open end of the filter element, and check whether the O-ring is intact and in place.

4. Moisten the O-ring and filter holder socket with a suitable wetting agent (such as water).

5. Hold the filter element close to the end of the O-ring, and vertically insert the filter element socket into the filter element holder socket completely.

6. After inserting all the filter elements, remove the filter element packaging bag, fasten the pressure plate to fix it, and then install the metal shell.

7. Open the air release valve on the top of the housing.

8. Rice slightly opens the inlet valve to allow the liquid to enter the casing until the liquid comes out from the deflation point on the top of the casing, and then close the deflation.

9. Slowly adjust and open the downstream outlet valve until it is fully opened.

10. Slowly adjust and open the inlet valve until it is fully opened. After this time, the pressure drop between the upstream and downstream of the filter is 0.02Mpa (the initial pressure drop under the determined flow rate).
