In contrast to classic cleaning, which is usually carried out using brush systems, Renson uses a powder specifically developed for this purpose, namely Apro-air, which is cleaned in a “swirling” manner and with several successive shock waves. is sprayed into the channels.

The result is astonishing. The powder loosens the dirt, granulates the grease present in the pipes, destroys bacteria and fungi and removes the loosened elements. In addition, Apro-air leaves an anti-static layer on the duct walls so that the dust has less grip and therefore does not quickly create a breeding ground for bacteria and other fungi. The final result is a neat ventilation duct.

To enjoy your Renson ventilation system C or D for as long as possible, we recommend that you have your system properly maintained by a professional.

Like this it is recommended to have the air ducts cleaned regularly. If dirt builds up in the ducts, it will reduce their diameter, providing your home with less fresh air than normal. The system will therefore have to make more effort to achieve the same result. The device itself also requires a technical inspection every so often for optimal operation. 

You should have this carried out by a professional:

• Cleaning of the appliance every 3 years heat exchanger and fans supplemented with a visual inspection of the air ducts. The technician will mainly focus on the air ducts.
• Mechanical and bacteriological cleaning of the air ducts every 9 years
