Overview
Part number F-300-21 from Johnson Controls, listed in Electric Actuators. KKM Solutions quotes this part with pricing and availability confirmed per order.
Overview The Johnson Controls D-3246-2 is a heavy-duty pneumatic piston damper actuator engineered for precise control and positioning of large dampers and inlet vanes on centrifugal fans and compressors within commercial and industrial HVAC systems. Designed with a rugged die-cast aluminum body and an effective 23.4 square inch diaphragm, it provides significant power stroke force to overcome high velocity airflow and static pressure. To ensure exceptional accuracy and eliminate hysteresis under varying loads, this model comes equipped with a factory-installed D-9502-5 pilot positioner for highly reliable proportional control. Features Precision Positioning: Factory-installed D-9502-5 pilot positioner eliminates hysteresis to ensure exact damper placement. Robust Construction: Built with a heavy-duty die-cast aluminum body and synthetic rubber diaphragm for long-term durability in demanding mechanical environments. Flexible Installation: Swivel mounting style includes a bracket, clevis, and crankarm hardware to simplify integration and alignment with various damper linkages. Optimized Efficiency: Low maximum air consumption rate of 2 SCIM reduces load and wear on the pneumatic plant. Specifications Actuator Type: Pneumatic / Diaphragm Piston Spring Range: 8 to 13 PSI (psig) Stroke Length: 6 inches Diaphragm Size: 23.4 square inches Maximum Control Air Pressure: 25 PSI Maximum Air Consumption: 2 SCIM Air Connection: 1/8 inch NPT Barbed Fitting (for 1/4 inch OD poly tubing) Weight: Approximately 22 to 26 lbs Country of Origin: Mexico Applications Commercial Air Handling Unit (AHU) and Variable Air Volume (VAV) damper control. Operation of inlet vanes on centrifugal fans and compressors. High-torque, large multi-blade damper positioning in industrial HVAC installations.
