Air Systems

The first Air System was called the M Series; this and the W Series are now completely obsolete but the next Turbo T Series pumps and parts are still available and most T Series parts fit the old M Series pumps if needed. However, recent developments to the air system provide significant advances in pump efficiencies and economies, that you wouldn't want to look past.

  • Pro-flo P Series i.e. P1, P2 - for most processes, has non stall (unbalanced spool), lube free operation, and  improved air usage performance.

Wilden Proflo

  •  Accu-flo i.e. A1 - for processes requiring direct electrical interface, system automation, external control and batch applications.
  • Pro-flo X PX Series i.e. PX1, PX4 - again for most processes, with non stall (unbalanced spool), lube free operation, improved air usage performance, but with additional 4 setting needle valve for greater air usage control. This is latest inprovement.
