Eaton Fuller Air Filter Regulator A-4740

A‑4740 Air Filter Regulator – Consistent OE‑Equivalent Aftermarket Quality

The A‑4740 air filter regulator functions as an integrated pneumatic filter regulator for heavy‑duty commercial vehicles equipped with Eaton Fuller manual transmissions. As a standardized aftermarket air filter assembly, the unit combines compressed air filtration and pressure regulation to eliminate moisture, particulate contaminants and residual oil within pneumatic pipelines.

Consistent air quality and stable pressure output protects transmission shift cylinders, control valves and the complete air actuation system from premature wear, air leakage and gear shifting malfunctions. Manufactured to universal OE‑style dimensional benchmarks, this heavy duty air filter serves as a direct drop‑in truck filter for all mainstream Class 8 semi truck models without structural modification.
