"name": "When should I choose the AOVH-10 instead of the smaller AOVH-5?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The AOVH-10 is the better choice when your hydraulic or lube oil system generates more heat than a compact cooler can handle. For higher duty cycles, slightly larger hydraulic power units, or small-to-mid gearboxes that run longer hours, the AOVH-10 provides more cooling surface area and airflow than the AOVH-5, helping keep oil temperature under control and extending component life."

"name": "What is the difference between the AOVH-10 and the AOVHR-10-2 two-pass version?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The AOVH-10 is a one-pass cooler, while the AOVHR-10-2 routes oil through the core twice and incorporates an integral relief bypass valve. The two-pass design increases cooling effectiveness, and the bypass valve helps protect against excessive backpressure during cold starts or high-viscosity operation. The AOVHR-10-2 typically covers about 4–60 GPM, making it ideal for return-line or dedicated cooling circuits with varying flow and temperature conditions."

"@type": "Question",
"name": "What kind of systems and fluids can the AOVH-10 be used with?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The AOVH-10 is suitable for hydraulic and lubrication systems using common mineral-based oils and many synthetics, as long as they are compatible with copper, aluminum, and steel and the system operates within the 300 psi and 400°F limits. Typical uses include hydraulic power units, machine tools, small presses, and gearboxes."

"@type": "Question",
"name": "What are the electrical and noise characteristics of the AOVH-10 fan motor?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The standard AOVH-10 uses a TEFC fan motor of approximately 1/2 HP, usually rated for 115/208–230 V, single-phase, 60 Hz, and running at around 3450 RPM. It operates in the mid-80 dB(A) range at rated airflow. Always verify the motor nameplate for exact electrical data and size wiring and protection accordingly."

"@type": "Question",
"name": "How should I mount and plumb the AOVH-10 for best performance and service life?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Mount the AOVH-10 horizontally with clear airflow around the fan and finned core, and provide room for service access. Pipe oil from the lower port to the upper port, preferably in the return line or a dedicated cooling loop. Use flexible connections where practical, keep the system well filtered to prevent fouling, and keep the cooler fins clean to maintain full cooling capacity."
