Precautions for using precision filters
1. Pay attention to whether the parameters such as the pressure, flow rate and temperature of the actual air used are within the allowable range of the precision filter, and pay attention to whether the above parameters have a large change during the use;
2. It should be noted that there is no corrosive gas in the filtered air and ambient air to avoid damage to the filter material and the filter housing;
3. Attention should be paid to the pressure difference between the inlet and outlet of the filter at any time. Under normal conditions, the pressure drop of the filter element increases slowly with the use time. When the maximum allowable pressure drop is reached, the working life of the filter element is indicated, and the filter element should be replaced (regenerated) in time. .
4. The step-up increase of the pressure drop of the filter element is abnormal. The cause should be found from the gas supply (for example, the sudden increase of the dust concentration in the intake air, the leakage of the gas pipeline and the valve, or the sudden increase of the gas load) Etc), should be dealt with according to the situation;
5. It should be noted that the automatic drainer at the bottom of the filter is working normally. The blockage of the drainer will cause water accumulation in the casing, which seriously affects the normal operation of the filter;
6. Renewable filters (such as metal sintered filter elements, ceramic filter elements and suction filters) should be cleaned and blown back in time according to regulations;
7. During operation, the filter housing is under pressure. When the filter is removed or the filter element is replaced, the pressure inside the casing must be released to atmospheric pressure;
8. If the filter is found to have a leak, remember to fill the leak with pressure.

All commercial and industrial businesses require the installation of Emergency Exit Sign lights. These exit sign for ABS emergency lights serve the important purpose of helping people leave the property quickly in the event of any emergency. The material of the emergency exit indicator is ABS fire engineering plastic, hard strength, good insulation performance, lightweight. The battery powered exit sign is suitable for use in public places such as schools, hallways, museums, etc. The letters "EXIT" can be customized or "EXIT" can be customized with arrows. It can be made single-sided or double-sided, and the letter color is red or green. The LED emergency exit signs is a test button in the lower right corner to manually check if the product is working properly. The fire exit signs are easy to install and can be hung on the wall or on the ceiling.
