Product Introduction

This full-size 610 × 610 mm panel incorporates a 20 mm polyolefin mat to deliver ISO Coarse 75% performance without a pleated cartridge. At the published 1300 m3/h nominal airflow, the assembled panel starts at 35 Pa. Its greater media depth makes it the appropriate flat-panel choice where downstream filters need stronger protection from coarse contamination.

Key Features

Highest flat-panel arrestance

The 20 mm medium provides the most substantial coarse-dust barrier among the three unpleated panel models.

Documented module duty

The 610 mm panel is paired with a published 1300 m3/h airflow and 35 Pa initial resistance.

Downstream filter protection

Improved large-particle removal can extend the useful loading interval of finer secondary filters.

Applications

Designed for outside-air and process-air intakes with noticeable lint or coarse dust, including clean manufacturing support areas and upstream stages protecting fine or HEPA filters. The full module is useful where a standard 610 mm rack is already installed.

Solutions for Your Application

Coarse loading shortens the life of expensive downstream filters.Use the ISO Coarse 75% panel as the accessible first stage to intercept more large particles.

A higher-arrestance pre-filter could exceed the available fan pressure.Evaluate the 35 Pa clean-panel resistance together with the system's loaded-filter allowance before selection.

Available Options

Confirm rack dimensions, airflow direction, frame construction and cleaning access; nonstandard finished sizes may be specified for compatible housings.
