A Radon fan should be ready for all these situations to guarantee a good quality mitigation system.įortunately, there are Radon fan producers who have a long history dealing with all these issues. Regardless of the climate or soil conditions, Radon fans usually work constantly without turning off, which could be some years. The last thing you want is a leak in the housing of your Radon fan. If you put the fan inside the building, the housing should be appropriately sealed. If you put the Radon fans outside, its housing could stay directly under the sun for a long time. The air from the ground brings humidity inside the fan motor. It also needs enough vacuum when dirt under the slab is packed with likely low system airflow. The fan should provide high airflow, energy efficiency, quiet operation, and effective Radon reduction. There are many factors to be considered when using a fan for a Mitigation project. The Radon fans should be specifically designed for Radon mitigation. Here are the questions:ġ- Could we consider any type of fan as a Radon fan?Ģ- Which Radon fan is proper for your Radon mitigation project?Īnswering the first question is easy. Knowing the importance of a Radon fan, we should also know which fan is suitable for an active SSD system. However, if you would like to learn more about SSD or other mitigation systems, follow the RadonMarket Mag here or visit the, in which new materials be available frequently. Therefore, we stop here our discussion on the SSD system and go forward to know more about Radon Fans. This section does not aim to discuss Radon mitigation methods.
In short, the Radon fan is responsible for continuously sucking the ground air in order to keep the ground pressure under the building always lower than the indoor pressure. Therefore the central part of any active SSD system would be the Radon fan.
In an active SSD system, a fan continuously sucks the air from the ground to decrease the ground pressure.
Plus, the passive SSD system is usually installed in new buildings, and many old buildings are not equipped with that. As a result, higher indoor pressure pushes the Radon laden air down and does not let it come up from the ground inside the building.Įven though a very small pressure difference is enough to achieve this goal, a passive system is not sufficient in many cases. In this approach, the air pressure in the ground beneath the building is kept lower than the indoor air pressure. The Sub Slab Depressurization (SSD) is the most common method to perform a Radon mitigation project. We start with the heart of any classical Radon mitigation system, which is the Radon Fan.įirst, we need some technical background on Radon mitigation approaches to know why we need a Radon Fan. Of course, we will continue to know more about CRM and other measuring instruments in the future, so continue to follow us on the main page of RadonMarket Mag.
In this number of RadonMarket Mag we would like to start a new series of reviews on the Radon Mitigation tools. Until now, we have always talked about continuous Radon monitors or so-called CRM (Continuous Radon Monitor).
