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.

Stainless steel security filter installation and use:

1. Thoroughly clean the filter housing.  

2. The inlet and outlet of the net shell are connected to the pipeline of the filtration system. Pay attention to the direction when connecting, and 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 opening 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 end of the filter element close to the O-ring, and vertically insert the filter element socket into the filter element 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 cover.  

7. Open the vent valve on the top of the housing.

8. Open the inlet valve slightly to allow the liquid to enter the housing until the liquid exits the vent valve at the top of the housing, at which point close the vent valve.                                                                  

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. At 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).
