XP/XR series fans are primarily used with high flow situations. This includes drain tile, gravel or where settling has occurred beneath the floor.
These fans are slightly less powerful than the RP series fans, but can be snugged up closer to a wall since they are all 8.5" inches in diameter.
The XP201 fan can handle a wide range of situations. Designed to move large quantities of air from drain tile systems or gravel. With a max suction of 1.9"WC this not recommended for tight soil conditions. Replaces discontinued model XP201c.
