- Determine reasonable levels of filter efficiency
Points determine the filter efficiency is: the final stage performance of the filter can be *, pre-filter efficiency specifications to be fair, a lower filter and pre-filter maintenance to be convenient.
- Increase filter area
Filter filter area, can accommodate more dust on its life is long. And filter area, the speed of air flow through the material is low, the resistance of the filter is small.
- Adjust the filter efficiency levels
Pre-filter filtration efficiency is low by adjusting the pre-filter filtration efficiency, dust blocked in the pre-filter.
- Cleaning is not widely
High efficiency filters, using the occasion is very particular, even washing the filter is not bad, it’s best not to wash, unless there is certainty thoroughly cleaned, after cleaning performance does not change.
