Air filter replacement standards and hose cleaning methods

The air filter is an adsorbent used to purify the air Devices for filtering dust and impurities are widely used and are commonly used in clean workshops, clean rooms, operating rooms, food production, biopharmaceuticals and other industries. Today the author will introduce to youair filter replacement standards and hose cleaning Method.

Air filter replacement standards and hose cleaning methods：

1. Under normal circumstances, the pressure of the primary-efficiency air filter and the medium-efficiency air filter reaches the initial resistance 2times or every three months must be replaced.

2When the high-efficiency air filter leaks, it should be replaced in time.

3, when the total air supply volume is less than 70%of the original air supply volume, all high-efficiency filters need to be replaced .

4, the wind speed does not meet the requirements, and the primary and medium effects are still not reached after replacement, the high-efficiency filter must be replaced immediately.

5. Under normal circumstances, the high-efficiency filter in the clean area should be replaced after three years of use.

6, old filter disposal and hose cleaning methods:

For the replaced old high-efficiency filter, apply 2% sodium bicarbonate or 0.5%sodium hydroxide spray Discard after being damaged by leaching; spray the hose interface of the high-efficiency filter with 0.5%sodium hydroxide, and then purify Rinse with water, and then use 0.2% of chlormethionine solution or 0.3 font>% hydrogen peroxide solution and wipe it, then it can be connected to the new high-efficiency filter.

Old primary and medium-efficiency filters must pass2% It can be discarded after cleaning with sodium bicarbonate.

Precautions for combined sub-high-efficiency air filter:

1. Replacement should be arranged during production shutdown for maintenance or production gap. Ensure that the unit is turned off before replacement.

2. After replacing the filter, a replacement record must be filled in.

3After replacement or before production again, the combined sub-high-efficiency filter must be tested for leaks and the environment must be tested. It can be put into use only if it meets the requirements. Otherwise, new measures should be taken.

That’s it for today’s introduction. If you want to know more about high-efficiency filters and filter glue, you can follow the author’s other content.
