  ● 20 psi continuous duty pressure rating
  ● Oil lubrication at both ends reduces bearing temperature and eliminates the need for greasing
  ● Bearing isolators are applied to meet the sealing at the high temperature
  ● Helical port design greatly reduces noise and smooths out airflow
  ● Low noise tri-lobe rotor
  ● Computer designed ribbing on body, end plates, and gear cases provides cooler discharge temperatures
  ● Easy Installation with vertical mounting kit
  ● Twin drive shaft offers either direction of rotation and ensures correct alignment of drive shaft upon  installation
  ● Packaged units available for on-site product transfer requirements

  Safe From Heat and Pressure
  ● Plug relieves 5-6 psi along with a 60-80°F drop in temperature
  ● One plug fitted on suction side and one on the delivery side
  ● Audibly alerts operator when plug melts at 22 psi
  ● Allows continued operation at lower pressure
  ● Plug does not eject molten material upon activation
  ● Consistent release of temperature from each plug

  Geared For Higher Efficiency
  ● Dynamically balanced efficient rotor for cooler operation
  ● Hardened teeth face for precision helical timing gear, taper-lock shaft mounting.
