Falcon 6504 Series

Reliable and Economical Full- or Part-Circle Rotor Pop-Up Sprinklers

With the Falcon 6504 rotor, you can have it all -- uncompromising performance, superior distribution, reliability and durability. Rain Curtain™ nozzles maximize performance and coverage. A multi-function wiper seal and tapered riser keep the stem clear of debris, providing long-term protection. Plus, heavy-duty construction makes the Falcon 6504 one of the toughest rotors in the field.

Available in full- and part-circle models with optional stainless steel riser, the Falcon 6504 is ideal for large turf sites such as parks, athletic fields, cemeteries, schools and commercial sites with spacing up to 65 feet (19,8 m).
