Brushes for air ducts

Brushes are important to clean air ducts correctly and effectively. Each brush is used for a different type of soiling, some for soft soiling and others for hard/caked-on soiling(s).

What's important?

During air duct cleaning it is important to use the right brushes. Not only the material of the brush is important, but also things like the right excess for the channel.

Choosing the right brush

Most air duct cleaning involves loose dust, which is usually quite soft in nature. In some cases one also suffers from heavier contaminants, which may be caked.

For 95% of the cases you can use a Nylon brush forward, so both the PDB and FPDB brushes are very common to use. This is used in combination with a power drill shaft such as an ecoflex.

In case of harder soiling we advise to use heavier brushes, here you should think of our Spider Brushes. These have a stronger nylon hair system, which scrapes the channels clean oversized.

Threaded or Inbus connection?

Most brushes are threaded. This is easy, simple and works on almost everything.

the only drawback is that you can only turn clockwise. As soon as you turn counterclockwise, the brush may become loose in the channel. This can be a problem if you have a lot of parkers in the canal. Sometimes the brush can get stuck to it.

Our FPDS shafts and FPDB brushes work with a unique socket connection. This allows you to turn both left and right without losing the brush.
Not only is this easier to clean, it is also a lot more effective.

Turning both left and right improves the cleaning effect enormously. Because you tackle pollution from multiple sides. So, for example, you enter the channel clockwise and exit the channel counterclockwise.

This ensures an optimal cleaning effect.

The right excess

In order to clean the air ducts properly, a brush should always be larger than the duct itself. In this way, you ensure that friction occurs and the bristles of the brush actually come into contact with the dirt.

The amount of excess does vary a lot between the diameters of the channels.
Because most air ducts that are cleaned are below 250 millimetres, we advise to always keep between 30 and 50 millimetres excess. (For larger diameters, this can lead to overruns).
