The purpose of chemical filtering is to prevent airborne corrosive, malodorous, or toxic gases from entering the indoor air and thereby to prevent their harmful effects on human health, electronic equipment, production processes, and products.

Corrosive gases include sulphur dioxide, hydrogen sulphide, chlorine, and ammonia. In sensitive electrical and electronic systems, condensation of gases on metal surfaces leads to malfunctions, changes, and damage that, in the worst-case scenario, may halt production entirely and thereby cause substantial direct economic harm.

Gases also often generate odours and thus cause reduce comfort and productivity, and even health.

Comprehensive solution from design to monitoring

Chemical filtering efficiently eliminates gaseous impurities from indoor supply air, recycled air, and the exhaust air. Our chemical filtering materials efficiently remove odours, gaseous impurities, and corrosion-inducing impurities in industrial and commercial business environments. Our chemical air cleaning services include assessment of the situation, solution design and calculation, just-in-time delivery, and filtration system monitoring.

Chemical filters are used for ventilation in, e.g., the following applications:

• Industrial electric rooms 
• Hospitals and laboratories 
• Museums 
• Recycled air in smoking rooms 
• Airports
