MF Series Hydraulic Oil Cooler with 12V DC Fan – 2-55 GPM, 300 PSI, 3/8" Tube, 1" NPT Ports, Heavy-Duty Aluminum Fins and Mounting Brackets – Model MF-15-1-4A. Part Number 258190

Heavy-Duty Cooling for Compact Hydraulic Systems: Part Number 258190Keep hydraulic oil within safe operating limits with the Thermal Transfer MF Series MF-15-1-4A Hydraulic Oil Cooler. Designed for compact to mid-size hydraulic systems, it supports 2–55 GPM in standard operation and can handle up to 175 GPM maximum flow. The built-in 12V DC fan delivers consistent airflow with low amp draw for energy-efficient performance. Rugged steel manifolds, 3/8" tube size, and aluminum fins provide long service life in challenging environments.With 1" NPT ports, plus SAE and 37° flare compatibility, installation is quick and secure using the included mounting brackets—no straps required. Rated for 300 PSI and oil temperatures up to 350°F, it offers heat removal capacity up to 50,000 BTU/Hr under ISO 32 hydraulic oil at 40°F approach test conditions. This ensures reliable cooling performance for forestry, agriculture, construction, and industrial equipment.Features:* Oil flow rate: 2–55 GPM (up to 175 GPM max)* Ports: 1" NPT (SAE and 37° flare compatible)* Tube size: 3/8"* Power: 12V DC fan motor, low amp draw* Heat removal: Up to 50,000 BTU/Hr (ISO 32 oil, 40°F approach)* Operating pressure: 300 PSI* Max oil temperature: 350°F* Construction: Heavy-duty steel manifolds with aluminum fins* Includes mounting brackets — no straps required* Dimensions: 13.88 L x 17.25 W x 4.99 Depth* Part number: 258190Built for Harsh EnvironmentsWhether mounted on forestry, construction, or agricultural machinery, the MF-15-1-4A is engineered for tough conditions—protecting your hydraulic components and maintaining system performance.Thermal Transfer, from Bailey International, Global Leader in Hydraulic Components & Electrical Controls.
