The Sealey SA4FR/38 is a professional air filter regulator designed to deliver clean, controlled compressed air for workshop pneumatic tools and equipment. Built with a heavy-duty aluminium alloy valve assembly, this unit combines filtration, water separation and pressure regulation in one compact housing, making it an efficient solution for both compressor mounting and air line installations. The integrated filter and water trap ensure contamination-free air delivery to protect your pneumatic tools from moisture and particulate damage. The large, easy-to-read gauge displays pressure readings in psi, bar and MPa, providing clear monitoring across different measurement preferences. With two individual compressed air outlets, each fitted with its own shut-off valve, this regulator allows independent control of multiple tools or workstations from a single unit. A lockable airflow control knob prevents accidental pressure adjustment during operation, maintaining consistent working pressure
