These grain retarders, grain slow downs, or flow retarders have internal baffles that slow the grain down and provide grain on grain contact to mitigate grain damage.
Flow retarders with inspection ports are recommended for use in VERTICAL spout runs every 20′-30′. Pricing includes round inlet and discharge. 10 gauge flow retarders have 3/16″ AR baffles and 7 gauge flow retarders have 1/2″ AR baffles. Urethane and ceramic tile liners are only available in painted units. Galvanized units must be lined with AR steel. Use urethane lined pricing for AR lined.
