When it comes to high-efficiency filters, I believe everyone understands the importance of the equipment, and in order to better extend the service life of the equipment, do we need to take certain effective measures? The way many users take is actually incorrect, so it has not reached The effect of rationality.
     Generally speaking, if you want to extend the service life of the high efficiency filter, the most fundamental way is to keep the dust in the pre-filter. The replacement of the pre-filter generally does not require suspension of production or debugging, so experienced owners will spend their attention and money on the pre-filter and the protective intermediate filter. For the 10K and 100K clean workshops, G4 can be selected for pre-filtering, and F8 filter (colorimetric 95%) can be used for intermediate. In this way, the service life of the end high-efficiency filter can generally be up to 5 years. In foreign projects and domestic new projects, F8 filter is the most common pre-filter for non-uniform flow clean room. In some occasions, the service life of the high efficiency filter is not based on the consideration of resistance, but other factors.
