Air filter cleaning method described below:
1, the air filter surface is not very dirty, the filter will get outdoor with clean compressed air double-sided purging, purging to see the light in the eye with no dust particles only.
2, the filter surface is dirty, the need for washing. In the general area of the water room (air-conditioned room) with the slot into the water of about 100 pounds of reference, the 1 kg bottle of detergent diluted, the filter into the tank to be submerged in the water. Rinse a number of times, to no pollution, and finally rinse with water until the clear water, remove the stainless steel grille to drag on the dry water, and then tiled on the shelf on the dry, Liangshuang to double-sided ground to turn in order to speed up the drying rate .
3, every day with a rag on the air conditioning cabinet surface and ancillary pipelines, instruments for a comprehensive cleaning, making the equipment clean and bright.
4, the equipment on the oil, plastic cloth to wipe clean with detergent after rinse, and then wipe clean drinking water, leaving no trace.
5, the initial effect of each replacement, the efficiency of the filter, the air conditioning unit should be the internal wall panels, fans, heaters, coolers, diffuser, a thorough cleaning, wipe dust, dirt, grease, Dead angle, and then install the initial effect and the effect filter.
6, the system should be cleaned once every half months, first with a wet cloth on the internal wipe, then dry cleaning cloth for a comprehensive clean.
7, the replacement of high efficiency air filter, the filter should be installed in the four boxes and the surrounding clean with a clean rag wipe clean, and to repeat three times, immediately after the installation of efficient filter wipe. HEPA filters should be unpacked in the field and checked for conformity and immediately installed to prevent dust from falling into the high efficiency filter.
8, the detection of the number of suspended particles in the clean room was significantly exceeded, the end of the high efficiency filter down to 70% of the initial air volume below.
9, high efficiency filter replacement, the dust particle counter for high efficiency filter and installation of leak detection junction. In the scanning inspection at the same time, fastening bolts or silicone plugging with epoxy resin.
10, high efficiency filter detection, replacement should be recorded in time.
11, high efficiency filter replacement, the leak test should be carried out and verified.
At the same time in the cleaning process need to pay attention to:
1, after the filter cloth is clean, if the initial resistance value of the filter is lower than the initial resistance value when the filter is installed for the first time, it should not be used and should be replaced in time. After the filter is washed twice, even if the pressure difference value is larger than the initial value, .
2, take high-efficiency filter, the box should be inverted, so that efficient filter landing smoothly.
3, the filter should be checked for damage after cleaning, if there should be timely replacement, cleaning can not be rubbed, nor machine wash or dry.
4, cleaning process, the initial effect of the filter to prohibit confusion, there should be numbers in order to distinguish.
5, each air purification system should have a backup set of filters to facilitate the timely replacement of cleaning.
