PressureTech PT25 is unlike anything else on the market!! This fan is capable of pulling 25 inches of suction or more! The PT25 Radon Mitigation Fan is not only perfect for radon mitigation but its also perfect for our Radon Pro Shop vapor intrusion customers as well! We are thrilled about this radon fan and we know all our mitigators will be too! The PT25 has many advantages over other radon fans thanks to the revolutionary DC motor technology that PressureTech has introduced. Direct Current (DC) motors are capable of much higher speeds and run more efficiently than traditional fan motors. The result is higher suction, higher airflow, and lower electrical consumption. By using less electricity, these fans save your clients money in operating costs and will outlast traditional motors that tend to burn out much sooner due to excessive heat. Due to lower electrical consumption than Alternating Current (AC) motors, DC motors run at much lower temperatures which extends the running life up to 5 times longer for our radon mitigation fans.
