General description

Made from durable galvanised steel, it features a removable cover for easy maintenance and is equipped with a synthetic glass fibre filter (G4 / 89% filter grade) that can be washed up to 8 times.

Installation

For optimal performance, install the filter box in front of the fan or sound absorber in the direction of airflow. Ensure there is sufficient clearance space according to dimension D for filter replacement. The filter box can be mounted in any position.

Usage

The filter must be cleaned when the initial pressure has doubled, and it should be replaced when it starts to decompose due to frequent washing. The filter box effectively absorbs approximately 135g/m² of dust, with a deposit rate of about 90%.
