Speed Control Mufflers
SPEEDAIRE speed control mufflers are designed for adjusting the speed of operating air cylinders and tools by controlling airflow on the exhaust ports of the air valve. They are equipped with a lock nut to maintain the operating speed. These mufflers feature brass construction and have a surrounding sleeve of sintered bronze to reduce exhaust air noise. Choose from a wide range of these exhaust port flow controls, available in 1-1/16, 1-5/16, 7/8, 9/16, 11/16 and 1/2 inch hex sizes on Raptor Supplies.
