Livestock Barn Circulation Fans
Product overview
AGRICULTURAL & LIVESTOCK VENTILATION
RAFAVENT large-diameter belt-driven axial fans circulate and mix air inside cattle barns. They support air movement at animal level but do not replace the required fresh-air and exhaust ventilation system.
Six-blade axial impeller designed for high-volume free-air circulation across stalls, feed lanes and holding areas.
Pulley ratio separates motor speed from impeller speed, allowing the impeller to operate at the selected low rotational speed.
Full metal mesh enclosure with guarded access. Door interlock and a fully enclosed belt guard are required in the final installation.
RF-LCF-1700 dimensions, motor rating and speeds are manufacturer-confirmed. Smaller models are preliminary engineering extensions derived by fan similarity and must be released by RAFAVENT engineering before order.
Preliminary estimated values—not certified ratings. Airflow is scaled from the RF-LCF-1700 design envelope using constant-tip-speed fan similarity. Final airflow, pressure, absorbed power and sound require controlled testing of the production configuration.
This product circulates existing barn air. Required outside-air ventilation, contaminant removal and summer/winter ventilation rates must be designed separately. Published estimated values are for preliminary selection only; certified performance is issued only after applicable production testing.
