World-class industrial air filters

How you benefit from our industrial air filters

Zehnder’s air cleaning solutions offer many different kinds of filter configurations, tailored to fit specific environments.

Filters can be divided into three basic types, based on the filtering method: electrostatic, compact and bag filters. Each filter type also comes in a number of different classes, ranging from coarse filters for catching larger particles, to what’s known as HEPA filters for much smaller, ultrafine dust, viruses and micro-organisms.

If you then factor in Zehnder’s extensive range of air purifiers which contain the filters, there are hundreds of possible combinations to capture many types of dust, fumes, oil mist, gases, germs, micro-organisms and viruses.

In most cases, we combine different filters to ensure the most effective performance of our air cleaning systems. If needs be, we can provide tailormade options, too. By doing this we ensure the best possible air quality in for your business.

Dust formation and definition

In simple terms, dust is a form of air pollution consisting of airborne particles often referred to as particulate matter (PM). Dust in industrial workplaces can occur naturally – as pollen, for example – or from human activity, including manufacturing, construction, farming and quarrying. Particulate matter comes in different sizes, most of which is invisible to the naked eye.

What are filter classes?

A filter class describes how well a filter performs in trapping different particle sizes/PM categories. As well as guaranteeing our filters meet rigorous requirements, it’s a good way to ensure you’re using the right product to filter out the type of dust particles in your workplace.
