As a member of the PAP Plus series, the A1 combines more than 60 years of operational and design experience in an extremely rugged and reliable package.

  • Flow: 45 – 100 m3/min | 1,500 – 3,500 CFM
  • Power: 190 – 595 kW | 260 – 800 hp
  • Pressure: 2.75 – 15.2 barg | 40 – 220 psig


PAP Plus A1 Features & Benefits

  • Designed to exact specifications – from API 672 to end users’ own complex needs.
  • Straight-through intercooler tube accommodates periodic cleaning, rather than replacement.
  • State-of-the-art, backward leaning impeller design that provides a broad range of superior aerodynamic performance characteristics.
  • Adjustable inlet guided vane adjust to plant conditions and load variations to save energy.
  • Full-capacity auxiliary oil pump continues normal, safe operation in the event of a main oil pump failure.
  • Filter monitoring package allows operators to receive real-time differential pressure of the oil and air filters.
  • Microprocessor-based smart transmitters capable of performing evaluations and producing diagnostics allow the operator to understand the condition of their compressed air system from a remote location.
  • Horizontally split gear case and internal components are integral features of the only truly field-serviceable gear box in the industry.
  • Regulus Control System allows the operator to control and manage the performance of one or multiple compressors, at the unit or remotely, to meet air demands while maximizing savings.
  • ISO 8573-1 CLASS 0, 100% oil-free air minimizes downtime from oil contamination in the production line and eliminates the need for off-site condensate disposal.
  • Engineered coatings designed for extreme conditions provide extended service life of internal and external surfaces, reduced maintenance, and corrosion prevention.
