Large fans in HVAC systems are often neglected. They lose their initial paint protection and develop surface rust.
This then causes further contamination down the supply air duct giving nutrients for mould and causing fall-out in the occupied space. No one can afford downtime on the fan during normal working hours so it is often left to carry on. Clean-air will restore the fan to original or better condition working after hours and having the system operational for each new day. Like all repainting projects success lies in the preparation and an excellent covering paint. We have several methods of preparing the fan surface including specialist tools and sand blasting which is isolated to the fan chamber. We use a 2 Part Epoxy Paint which gives a strong and resilient finish.
