Ventilation and air conditioning system needs the protection of the air filter
Air-conditioning maintenance personnel will usually find air conditioning system in use after a long time to find the following questions:
1. The fan, heat exchanger, air valve, pipe parts, such as serious dust, and there is peculiar smell
2. The system is running after a few years, air volume and low cold/hot processing, to meet the original design requirements;
3. and a black stains around the comfort air conditioning air supply outlet;
4. The indoor workers complain about air pollution, physical discomfort;
5. Clean room system of high efficiency air filter resistance increase too fast, even 1-2 years will need to change;
6. Long for air conditioner in the distribution of metal/nylon netting and chemical fiber non-woven, even if not to clean, resistance will not continue to rise;
The main cause of these problems is dust, so-called washable filter for dust block is limited. In addition to stop the air conditioning system for cleaning, or replace expensive system components, more effective measures is to establish high enough air filter efficiency.(domestic cleaning service companies rarely can provide air conditioning system. Through the investigation and research of developed countries show that glass fiber bag filter is the most economic and effective user choice.
