Glass fiber media

Glass fiber media

The thick package of enhanced glass fiber media used in our filters, ensures high filter efficiency, low pressure drop and guaranteed lifetime performance. In oil coalescing filters Atlas Copco chooses to make use of wrapping technology instead of pleating. 

So why is Atlas Copco not making use of pleated technology?

Pleating is less reliable than wrapping. When testing filters with pleated filter media, we regularly observe cracks in the filter media. This is absolutely normal since pleating stretches the filter media, causing local stress. Cracked filter media lead to oil breakthrough and thus poor air quality.
