Is your radon system too noisy?  Do your neighbors hate your radon noise?  PDS’ radon noise muffler is best for when outdoor noise is an issue.  Used for when radon exhaust is too loud.  For noise heard inside the home, try LDVI couplers.  The PDS muffler uses 6″ pipe in order to reduce noise while having minimal effects on airflow. The radon muffler can be installed anywhere above the fan (exhaust side).  Female inlet connects using PVC glue to 4″ schedule 40.
