Product Introduction

This 292 mm galvanized box contains a dual-density glass-fiber pack separated by aluminum sheets and rated MERV 15. It retains the handling strength and airflow stability of the full-depth family while moving to its highest listed efficiency. The model is intended for critical intermediate positions where a rigid cell must withstand turbulent supply air and limit fine-particle loading on final filters.

Key Features

Top family efficiency

MERV 15 media provides the finest particulate control among these three rigid-box variants.

Pressure-stable cell

The galvanized enclosure and aluminum separators resist pack movement in demanding HVAC duty.

HEPA life support

Higher upstream capture can reduce the amount of fine dust accumulating on the terminal stage.

Applications

Applicable to cleanroom air handlers, hospital supply ventilation and controlled production systems where an elevated intermediate grade is required. It is best used in housings with enough depth and fan capacity for a full MERV 15 rigid cell.

Solutions for Your Application

A flexible filter pack is vulnerable to turbulent airflow near the fan section.The rigid metal cell and separator-supported medium hold a defined geometry at the filter bank.

The final HEPA bank receives excessive small-particle loading.MERV 15 intermediate filtration removes more fine particulate before it reaches the terminal stage.

Available Options

Confirm filter-bank depth, face dimensions, gasket side and header arrangement; set the change-out limit from the actual fan-pressure budget.
