Vanair highly recommends consulting a hydraulic supply expert for specifying the oil reservoir size, hydraulic cooler, additional pressure relief(s), and other hydraulic supply components for your application. Please take into consideration the following:

  • The Hydraulic Flow and Pressure Requirements of the Hydraulic Tools
  • When Hydraulic Tools are Running, There is a Continuous Hydraulic Load and an External Hydraulic Cooler is Needed
  • Duty Cycle and Ambient Operating Temperatures.
