How to find leaks in high-efficiency filters, and what are the methods

The HEPA filter without clapboard is a kind of air filter with the ability of high efficiency filtration. It uses a filter made of electrostatic spinning technology, which has high filtration efficiency and low resistance.

It is often used in places that require advanced filtration, such as hospitals, laboratories, food factories, semiconductor factories, etc. It can effectively remove tiny particles such as bacteria, viruses, dust, smoke, etc. At the same time, it can also reduce indoor air pollution and improve indoor environmental quality.

The knife holder type high efficiency filter has the advantages of simple structure, long service life, and easy maintenance, but there are also some disadvantages, such as high cost and difficulty in replacing the filter screen.

HEPA filter leak detection is an important job, it can help to protect the quality of the environment and people's health and safety. The following will introduce how to complete this work through the leak detection of the knife holder type high efficiency filter.

Step 1: Preparations

Before performing leak detection of high-efficiency filters, it is necessary to know the type, specifications and performance parameters of the filter in order to carry out correct detection methods and processes. At the same time, you need to prepare the tools needed for leak detection, including leak detectors, flashlights, rulers, notebooks, etc.

Step Two: Check the Filter Appearance

First of all, it is necessary to observe whether the surface of the filter is loose, deformed, damaged, etc. These may be factors that cause leakage. In addition, check whether the filter interface, O-ring, filter element seat and other parts are clean and free of dirt, to ensure that its structure is intact and the seal is firm.

Step 3: Use tool holder tool detection

It is a relatively simple method to detect the leak of the knife holder type HEPA filter by using the knife holder, and it can also quickly and accurately diagnose the leak point of the filter.

The specific operation process is as follows:

1. Install the filter on the knife holder and adjust the knife holder.

2. Connect the leak detector to the knife holder and test each plug one by one.

3. At the beginning of the test, turn on the flash and observe whether there is leakage everywhere in the filter.

4. Where the leak is found, record the location of the leak with a notebook and mark it.

5. Repair or replace the leakage point, and test again to see if there is still leakage.

Step 4: Judgment and processing of test results

After the test is completed, the test results should be judged and processed. If there is a leak, it needs to be repaired or replaced in time. If the filter is normal, it is necessary to set a warning line for timely replacement or maintenance.

In short, the leak detection of high-efficiency filters is a job that needs to be taken seriously. Only by doing a good job in leak detection can the normal use of the filter be guaranteed, and the environment and people's health and safety can be guaranteed.
