Fibre Glass (GL)

Fibre Glass (GL)

Due to its mechanical properties fibreglass gets only used in form of a woven fabric, additionally laminated with an ePTFE membrane.

Converting of fibreglass filter bags requires strict tolerances to ensure a sufficient performance. In addition the support cages need to follow a special “fibreglass-cage-specification”.

To meet low emissions and a constant low pressure drop, woven fibreglass mostly is laminated with an ePTFE membrane.
