DuoLine HE Bags

Designed to provide effective filtration for a wide range of applications using a variety of graded filter media.

DuoLine HE bags are manufactured using multi-layered polypropylene microfibre media with built in pre-filter layers. The progressive density depth filtration delivers high efficiency of up to 99.9% positive and controlled solids removal. The multi-layered construction of the HE Bag uses varying thickness of media to create a depth type filter with up to 12 different grades of material.

Available in 2 diameters – 4¼” and 7”, both fitted as standard with a top ring locator in various materials and styles.
Designed to filter from the inside to out leaving the contamination inside the bag for simple disposal.
