PAP Plus DH 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 allows 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.

Case Study: Industrial Gas Producer Reduced Capital Expenditures & Increased Efficiency

Case Study

Learn how an industrial gas producer reduced capital expenditures and increased overall efficiency.

Condensate Drain

Provides a regulated discharge of condensate and eliminates the loss of compressed air.
Control Systems

Featuring the most powerful processors in the industry, the Regulus line offers unprecedented compressor control, providing reliable, efficient operations and substantial energy savings.
Drain Bypass

Innovative solution for removing condensate from intercoolers and aftercoolers that provide maintainability and reliability benefits to the condensate drain system.
Drain Valve

Only discharges condensate when the reservoir is full, eliminating water without losing air.
Fabricated Sub-Skids

Provided when a complete, pre-piped, and pre-wired package is desired for minimal installation on site.
Sound Attenuation

Accommodates installations with special acoustic requirements.
