Solair HPUs are engineered to last, inside and out, so you can count on it to perform test after test, year after year.

  • Inside – Our HPUs incorporate a dual pump package standard. Made up of one charge pump and a main pressure pump, the charge pump ensures a constant supply of fluid to the main pump, preventing cavitations and extending the life of the main pump. Fluid is directed through a custom machined aluminum block manifold.
  • Out – Our cabinets are welded aluminum or steel, consisting of a base and top joined during manufacturing. Never a patchwork of riveted panels.
