Product Introduction

This wet-laid glass-microfiber sheet is intended for H13 mini-pleat and separator HEPA constructions. Its fiber distribution is controlled for media uniformity, dust holding and stable pleating, while the H13 target allows a lower resistance design than the H14 and U15 versions in the same material family. Final filter classification still depends on the complete pack, seals, frame and individual test under EN 1822 or ISO 29463.

Key Features

Balanced H13 resistance

The fiber structure targets final-filter efficiency without the density required for the higher grades.

Uniform sheet formation

Controlled wet laying supports repeatable pleat resistance and local penetration behavior.

Multiple pack formats

The media can be converted into mini-pleat or separator constructions with suitable handling.

Applications

For healthcare, pharmaceutical and clean-manufacturing HEPA filters where H13 efficiency is appropriate and glass media is accepted.

Solutions for Your Application

Media roll data is treated as proof that every assembled filter is H13.Control pleating and sealing, then classify the finished element by the applicable individual filter test.

Glass microfiber is cracked during tight pleating or rough handling.Set pleat geometry and converter tension for the sheet and protect rolls and packs from folds and impact.

Available Options

Confirm basis weight, roll width, pleat depth, separator or hot-melt spacing, target resistance, sealant and finished-filter test method.
