Filtration Abbreviations Explained: A to I

Everyday at Classic Filters we use abbreviations to save time and space in documentation for manufacturing filters, but lots of people ask the question “what do they mean” and do you personally know what they all mean?

Well we have decided to shed some light on the situation and give you a helping hand by explaining what they mean.

As there are so many different abbreviations we have decided to talk about the topic in two posts. This post will take you from A to I and let you absorb this round of terms.
