SMC AS Series Flow Controller Speed Controller Threaded AS3500-N02

SMC AS3500-N02 Flow Controller Speed Controller Threaded is a high-precision pneumatic speed controller from the renowned SMC AS series, designed for effective flow regulation in pneumatic systems. It offers an in-line locking type configuration, allowing users to lock the speed setting conveniently with a push-button mechanism, ensuring consistent performance during repeated use. The speed control adjustments are clearly indicated to facilitate easy and accurate repeatability.

This speed controller precisely controls airflow velocity, even at low speeds, ensuring optimal actuator operation. It is designed primarily for meter out only free flow return pneumatic circuits, maintaining constant speed for enhanced system performance. The robust metal control knob provides durability under rigorous industrial usage while a retaining function secures the needle to prevent loss and maintain precise adjustment.

Constructed from a combination of brass, zinc chromated materials, electroless nickel plating, nitrile butadiene rubber (NBR), hydrogenated nitrile butadiene rubber (HNBR), stainless steel, polybutylene terephthalate (PBT), steel, and polyoxymethylene (POM), this controller ensures high durability and chemical resistance. The unit operates efficiently across a temperature range of -5°C to 60°C and withstands a maximum operating pressure of 1 MPa with proof pressure capability up to 1.5 MPa, making it suitable for demanding pneumatic applications.

This model meets the UL Standard V-0 for safety and flame retardancy, making it a reliable choice for industrial environments requiring compliance with safety standards. Made in Japan, the AS3500-N02 delivers trusted performance for pneumatic flow regulation in industrial automation, HVAC, manufacturing, and fluid power tools sectors.

The in-line locking type design enables speed setting lock at the touch of a button. Speed control settings are clearly marked to ensure repeatability. Accurate speed control is maintained even at low velocity applications.

Constant speed can be easily set for meter out only free flow return systems. Equipped with a metal control knob for durability under heavy usage. A retaining function prevents loss of needle during operation. Constructed from brass, electroless nickel plating, stainless steel, and high-performance polymers for durability.

Operating temperature ranges from -5°C to 60°C suitable for various industrial environments. Designed to handle maximum operating pressure up to 1 MPa with a proof pressure of 1.5 MPa. Compliant with UL Standard V-0 for safety and flammability resistance.

This flow controller is ideal for industrial automation, laboratory pneumatics, fluid power systems, and manufacturing applications requiring precise speed and flow control. For more Pneumatic Function Fittings and control devices, explore the EnvMart catalog.
