Product Introduction

This model uses 44 mm fiberglass medium with scrim reinforcement on a 65 ft roll. Its progressive depth-loading structure begins at 0.14 in. w.g. resistance and provides referenced arrestance of 70–85%. It is intended for large automatic-roll housings designed to handle glass-fiber media, rather than as a direct substitute in systems specified for synthetic rolls.

Key Features

Progressive glass-fiber loading

The depth structure captures coarse debris through the media thickness as the exposed section accumulates dust.

Long renewable supply

A 65 ft roll provides multiple fresh filtering sections for automatic indexing.

Scrim-supported feed

Reinforcement helps the thick fiberglass medium move through compatible roll-filter hardware.

Applications

Used in large outside-air and industrial AHUs equipped with compatible automatic roll hardware. The fiberglass medium is selected where the established housing, drive system and maintenance practice are designed for progressive glass-fiber media.

Solutions for Your Application

A synthetic roll does not match the installed mechanism or established media specification.Use the scrim-backed fiberglass roll only after confirming width, shaft and feed compatibility with the housing.

Thick glass media sheds or tears during improper handling.Keep the roll wrapped until installation, support it during loading and set drive tension for the reinforced medium.

Available Options

Confirm finished roll width, spindle size, winding direction, media advance length and enclosure compatibility.
