G3 G4 Panel Initial Effect Air Filter
diamond -shaped nursing nets to ensure that the filter is not deformed or damaged in a poor working environment; lightweight plate structures. Filtering materials use a good polyester synthetic fiber, which can be cleaned and reused multiple times. The service life is long, economic and practical, fluffy and dense fibrous structures, which ensure a higher dust rate and a large amount of dust. Effectively extend the service life of its back -end mid -effect filter. 1 -inch (21mm, 25mm) Different thickness is available. You can choose filtering levels: G2, G3, G4 (EN779). The use of flat -flat early -effect filters: office buildings, conference rooms, hospitals, shopping malls, airports and other large civilian building ventilation air -conditioning systems, ordinary industrial plants or clean air -conditioning systems in a clean air conditioning system. If there is too much dust in the environment used by the first -effect filter, the number of cleaning times should be increased depending on the situation, which is generally once half a year.
Primary and selection principles: Early efficiency filter filtering accuracy and selection principles:
1. Preliminary filter filtering accuracy -The air filter corrects the filter feature correctly. The characteristics of filter are mainly filter efficiency, resistance, penetration rate, dust capacity, filtering wind speed, and processing air volume. Under the condition of conditions, you should choose a filter with as much as possible, low resistance, large dust capacity, moderate filtration air speed, large processing air volume, convenient manufacturing and installation, and low price. This is the economic analysis needs of one -time and multi -time and energy efficiency when the air filter selection.
2. Preliminary filter filtering accuracy -Air filter analysis of the nature of dust -containing gas. The nature of the dust -containing gases related to the choice of air filters is the number of temperature, humidity, acid and alkali -containing and organic solvents. Because some filters are allowed to be used at high temperatures, and some filters can only work at room temperature and normally humidity, and the amount of acid -alkali content and organic solvents of the dust -containing gas affects the performance efficiency of the air filter. The outer frame of the folding shape of the first -effect G3 G4 air filter manufacturer is fixed with the diagonal line.
