Air ducts have a tendency of becoming very dirty, regardless of where it's being used. However, in industrial environments it's even more difficult to keep your air ducts clean, as the air in an industrial environment often is far dirtier than in residential environments. A dirty air duct is not beneficial for the working environment, and it can also lead to issues with the functionality of the spiral ducting. In order to make sure that you have a good air quality in your working place, there are a few things you should know about cleaning air ducts.


The first thing you should do to clean your air duct is to use a brush to loosen the dirt from the sides of the spiral welded pipe. This makes it easier to collect the dust, and minimises the risk of any dirt still being stuck in the air duct after cleaning. Use a brush with a long enough handle to reach to every place throughout the entire length of the spiral tubing and avoid putting any weight on the pipe to avoid accidents. You can also use a mechanical rotary brush for even more efficient cleaning.

Sucking or blowing

You'll also need to gather the dirt that has come loose from brushing the insides of the duct. You can do this in two ways. You could use a industrial vacuum cleaner to suck the dirt out of the tube. As most companies own a vacuum cleaner of this type, it's often the simplest option. It might, however, be difficult to use a vacuum cleaner this way, as there aren't many vacuum cleaners that come with an extension long enough to reach through the entire spiral welded pipe. You can also use compressed air to blow the dirt out of the tube. This is an effective method that is likely to get all the dirt out of the pipe. Just remember to do this after working hours to prevent people getting dust and dirt on them.


For the best result possible, you'll also need to wash the duct. Make sure that all electrical equipment in proximity to the duct is turned off and then use a high pressure washer to spray the insides of the pipe with water. Avoid using any types of detergents as this might damage the inside of the pipes and also spread an irritating smell in the work place. You should let the pipe dry completely before using it again, as it might attract even more dirt that'll stick to it when it's wet.
