monofilament filter bags feature a wide range of retention ratings. The different materials cover many applications with demanding chemical and thermal properties. These filter bags are designed for surface filtration to retain particles that are larger than the respective pore size.

SENTINEL and SNAP-RING mono-filament filter bags for surface filtration
• Non-deformable mono-filament material is woven into a specific pattern with fusion-welded intersections for extra strength and a retention rating
• All nylon mono-filament filter bags with the FDA seal ring have an inseam for safe filtration
• All nylon mono-filament grades <125 micro are manufactured with a twill-tape envelope on the side seam and bottom seam to prevent liquid bypass through the needle holes
• The pressure-activated FDA seal ring provides a flexible, chemically resistant seal which adapts to any bag filter housing
• Doctopfilter strongly recommends the use of an insertion tool that facilitates the insertion of the filter bag into the bag filter housing and ensures the correct alignment of the filter bag inside the restrainer basket
