Product Introduction

This automatic-roll selection uses 38 mm synthetic scrim media, twice the nominal thickness of the long low-drop synthetic version. The heavier pack provides greater dust-holding depth but shortens the roll to 45 ft and increases initial resistance to 0.19 in. w.g. Referenced arrestance remains 70–85%, making it suitable for dustier intakes where capacity per exposed section matters more than minimum resistance.

Key Features

Higher media mass

The 38 mm depth provides more fiber volume for dust loading across each indexed section.

Dust-focused tradeoff

A shorter roll and higher resistance are accepted in exchange for greater local holding capacity.

Automatic surface renewal

The mechanism exposes a fresh filter section when the control system commands an advance.

Technical Parameters

Roll Length	45 ft
Media Thickness	38 mm
Filter Medium	High-mass synthetic fiber with scrim
Clean Resistance	0.19 in. w.g.
Arrestance Range	70–85%
Media Movement	Automatic roll advance
Capacity Characteristic	Higher dust depth per exposed section
Intended Air	Dusty industrial intake
Selection Tradeoff	Higher capacity with shorter roll length
Customization	Available based on the intended application and operating environment.

Applications

Intended for industrial outside-air systems and large process-support AHUs with significant coarse dust. It is selected when a thicker exposed filter section is more valuable than the longer replacement interval and lower resistance of the 65 ft synthetic roll.

Solutions for Your Application

Lightweight roll media advances often because each exposed section loads rapidly.The 38 mm high-mass medium provides greater depth loading at each indexed position.

The fan cannot tolerate the resistance of the thicker automatic medium.Include the 0.19 in. w.g. clean value and the control setpoint in the fan-pressure review before selection.

Available Options

Specify roll width, core or shaft interface, winding direction, controller setpoint and available pressure allowance.
