Pocket filters

Pocket filters are used to filter particles from the air in ventilation units. It's best to choose a pocket filter with low energy consumption and high dust holding capacity. Pocket filters are used in all kinds of applications, from schools and offices to industries and hospitals. Bag filters are air filters that help improve (indoor) air quality. An air handling unit, often on top of a building, contains several air filters. One of these filters is usually a pocket filter. The pocket filter is often used as a pre-filter. This pocket filter catches the largest particles so that the filters in the second stage can catch the smaller particles. 

Choice of pocket filter

Make sure that the company you are purchasing pocket filters from is certified by Eurovent, this ensures that the company's marketing is accurate and audited by Eurovent during production visits. Eurovent selects pocket filters from production for testing at independent certified testing institutes. The result of the test is compared with the marketing data to ensure that they are correct.

What are the benefits of pocket filters?

Energy costs can be significantly reduced by installing pocket filters from AAF. Bag filters have extremely low energy consumption. Some air filter versions are lightweight due to the sturdy plastic frame. When the pocket filters need to be replaced, this can be done faster, providing additional cost savings. Pocket filters have a large filter surface area, allowing them to filter large areas and thus have a very high dust retention capacity.

Accommodation and long-term stays

In offices, schools and hotels, for example, the pocket filter should be of class ePM1. Bag filters of this class filter the smallest and most dangerous particles for humans. As a rule, this filter class should be used for supply air in all rooms where people stay for long periods of time.

Exhaust air and short-stay areas

For exhaust air and areas where people stay for shorter periods, e.g. waste rooms and stairwells, etc., there are lower requirements and an ePM10 filter is usually sufficient.
