Gas Adsorption Filters

Available in a variety of formats, MANN+HUMMEL's gas adsorption filters utilise a variety of materials including the latest impregnated and activated carbons. Designed for the elimination of odours and toxic or harmful gases, these carbon filters provide the ideal solution for preserving comfort air, and protecting people and processes in cleanroom environments.

AFP-AZ Duo

Introduction

Removing particles and odours from a ventilation system is usually a two-stage affair. With AFP-AZ Duo, however, this is no longer the case. By combining the two stages into one, AFP-AZ Duo makes air filtration of particulates and odours simple and more cost effective.

Firstly a high efficiency synthetic media layer removes the dust particles providing a filter efficiency of F7 (to EN 779). Then a high quality, activated carbon composite material removes the odours, making the air feel and smell cleaner.

Two stage cleaning of air is essential in buildings where high levels of contamination occur from traffic fumes or production processes. Often air-handling units are only designed for single stage cleaning. By combining the two stages into one standard size filter, AFP-AZ Duo offers the capability to clean air streams of particulates as well as odours without adding an expensive extra process to the ventilation system.

Being only 300mm deep and made of lightweight materials, the standard AFP-AZ Duo filter can fit directly into an air-handling unit replacing a single stage particle or odour filter with the more effective combination unit.
