Product Introduction

This 48 mm pleated panel changes the frame material rather than the filtration class. A molded plastic perimeter carries ISO Coarse 65% synthetic media on a 592 × 592 mm face, providing improved resistance to humid service compared with cardboard and avoiding exposed galvanized edges. The complete unit is suited to clean-process intakes near washdown areas when direct liquid impingement is prevented.

Key Features

Humidity-resistant perimeter

The molded frame does not rely on absorbent board and is appropriate for damp ventilation environments.

Washdown-adjacent suitability

Plastic framing reduces corrosion concerns near cleaned process areas while the filter remains protected from direct spray.

Incinerable frame option

The plastic construction can support energy-recovery disposal routes where local facilities accept the complete filter.

Applications

Intended for humid clean-process air intakes, food and beverage support spaces and ventilation located near routine washdown activity. It provides coarse prefiltration where a molded non-absorbent frame is preferable to cardboard or conventional metal construction.

Solutions for Your Application

Moisture softens a board frame or promotes corrosion around a metal perimeter.The molded plastic frame provides a non-absorbent, corrosion-resistant edge for humid HVAC service.

Operators assume humidity resistance means the filter can be directly sprayed.Keep the panel outside the direct wash path and use drainage or droplet separation ahead of the filter.

Available Options

Confirm face size, molded frame profile, gasket requirement, airflow direction and the expected humidity and cleaning exposure.
