References you can read without filling in a form: air filtration classes, high efficiency filters, choosing a medium, trade vocabulary and recurring questions.
Air filtration classes
This page serves two readers: the one who needs to know what an efficiency class actually measures, and the one holding a nameplate that carries a class no longer to be found anywhere.
High efficiency filters
Beyond a certain level of demand, a filter is no longer characterised by an average: it is characterised by its weakest point. That is what the high efficiency classification measures, and what almost no catalogue explains.
Guide to choosing a filter medium
Choosing a medium turns on four questions, in this order. The table above covers only one of them — temperature — and it is the only one for which we hold evidenced values, document in hand.
Glossary of industrial filtration
This glossary defines words as this site and manufacturers' documentation use them. Each term carries its own anchor: you can send a link to one definition.
Technical questions on selection and sizing
The questions above are the ones maintenance managers actually put to us. Each carries its own anchor: you can send a link to one answer.
