American Industrial Supply Co. brings buyers and sellers together through a marketplace for used industrial equipment, including air pressure regulators. Browse available listings to compare regulator types, brands, and specifications for your application, or offer equipment that is no longer needed. Product details and availability can vary by listing, so review the information provided to determine whether a regulator fits your system. Explore options from manufacturers such as Swagelok.
Air pressure regulators reduce and control downstream pressure from a compressed-air source, helping pneumatic systems operate within a selected pressure range. They are used in manufacturing equipment, automation, packaging lines, workshops, and other applications that rely on controlled airflow. Depending on the system, buyers may consider relieving or non-relieving designs, precision regulators, flow capacity, connection size, pressure range, and compatibility with the air supply.
The cost of a used air pressure regulator can vary with its brand, model, configuration, pressure and flow ratings, materials, condition as described in the listing, and current availability. Specialized precision regulators or units suited to particular industrial processes may be priced differently from general-purpose pneumatic regulators. Comparing specifications and listing details can help buyers assess options within their budgets.
As industrial systems adopted compressed air for powering machinery and controls, regulators became important for managing pressure between the air source and equipment. Mechanical designs developed to use components such as springs, diaphragms, and adjustment knobs to maintain a more consistent downstream pressure as operating conditions change. Modern air pressure regulator equipment is available in many configurations, from compact pneumatic units to precision models for applications requiring finer pressure control.
