The RP265 is a very high flow fan rated at 95-152 watts. This fan is usually used with large drain tile systems and gravel only. It also has the ability to suck hard with a maximum pressure of 2.5WC. Great for basements larger than 2500 sq/ft. A good choice for higher radon levels in large finished basements where crack filling isn't possible or where multiple suction points may be needed with possible high air flow rates.
Note: Utility cords need to be purchased separately. The RP265 has 6" openings thus requiring 4"x6" rubber couplings for mounting. 4" pipe is required for the RP260. Varmint guards are a must to protect your fans warranty.
