Balston AFR920A-130 Air Filter Regulator Exhaust Filter

Balston AFR920A-130 (also listed as AFR920-130) is a 1/4" NPT filter-regulator that combines a Balston coalescing air filter with a precision regulator to deliver clean, regulated air to downstream equipment. The unit supports a 10–130 psi regulation range and is designed to remove oil, water, and dirt from compressed air via a Balston coalescing element, protecting downstream cylinders, valves, and tools. Its durable construction features an anodized aluminum head, brass internals, Buna-N O-rings, and a polycarbonate bowl, and the assembly weighs about 1.92 lb. This AFR920-130/AFR920A-130 is noted as discontinued by the manufacturer, suggesting it has been superseded by newer Balston AFR variants, but the 1/4" NPT ports and the 10–130 psi operating window remain representative of small-to-mid flow systems. Typical applications include automation panels, pneumatic tooling, and general shop air systems where oil- and moisture-free air at a controlled pressure is essential.
