Product Introduction

This nominal 292 mm rigid filter uses meltblown synthetic media in a galvanized steel frame. Its MERV 11 family rating provides moderate intermediate filtration while avoiding a glass-fiber media pack. The moisture-resistant, metal-backed pleat structure is intended for general clean-process AHUs exposed to humidity changes and repeated fan cycling.

Key Features

Glass-free media choice

Meltblown synthetic fibers provide an alternative where a glass-fiber filter medium is not preferred.

Humidity-tolerant construction

The synthetic pack is suited to normal HVAC moisture variation without relying on paper-like support.

Variable-flow stability

A rigid metal-backed pleat assembly limits movement through changing air-volume conditions.

Applications

Used in general clean-process AHUs, humid outside-air sections and ventilation systems with frequent fan start-stop cycles. The MERV 11 model is appropriate when durable synthetic media is desired without specifying the higher resistance of a finer grade.

Solutions for Your Application

Glass-fiber media is unsuitable for the facility's handling preference.The meltblown synthetic pack provides a glass-free medium inside a protected rigid cell.

Repeated humidity and fan cycling distort a conventional filter.Use the moisture-resistant, metal-backed pleat structure and maintain effective upstream drainage.

Available Options

Choose MERV 11 or 12 family performance, face dimensions, header style and gasket configuration for the AHU bank.
