Prevost PPS Aluminum Flange Adapter (PPS1 UF)

The Prevost PPS1 UF Aluminum Flange Adapter is a heavy-duty connection interface designed to bridge the gap between large-diameter industrial equipment and the Prevost Piping System (PPS). This flange is specifically engineered to bolt directly onto the outlet of large air compressors, dryers, or receiver tanks, providing an immediate, high-flow transition to Prevost aluminum piping.

Eliminating the need for massive threaded fittings, which can be difficult to tighten and seal at large diameters, the PPS1 UF offers a secure, bolt-on solution that simplifies the installation of main header lines in industrial plant rooms.

Key Features & Benefits

• Direct Compressor Integration: Designed to bolt onto standard industrial flange patterns, enabling a seamless connection from the compressor room to the distribution network.
• High-Volume Flow: The open flange design maximizes the bore size, ensuring zero restriction at the critical “start” of the air system where volume and velocity are highest.
• Simplified Maintenance: Unlike threaded connections that are permanent, a flange connection can be easily unbolted. This allows for rapid disconnection of the pipe network if the compressor needs servicing or replacement.
• Secure & Rigid: Provides an exceptionally strong mechanical connection that can withstand the vibration and thermal cycles often found near compressor outlets.
• PPS Grip Technology: The pipe-side connection features Prevost’s standard push-to-connect (or torque-tighten) technology, allowing the aluminum pipe to slide directly into the flange adapter without welding or threading.

Technical Specifications

• Part Series: PPS1 UF (Union Flange)
• Material: Aluminum Alloy (Body) / Stainless Steel (Grip Ring)
• Connection Type:
  • Side A: Industrial Flange Face (Requires gasket and bolts)
  • Side B: PPS Connection for Aluminum Pipe
• Operating Pressure: Up to 232 PSI (16 bar)
• Operating Temperature: -4°F to +176°F (-20°C to +80°C)
• Fluid Compatibility: Compressed Air, Vacuum, Nitrogen
• Standards: Compatible with standard industrial flange dimensions (e.g., DIN/ANSI patterns—check specific part number for exact bolt pattern match).

Ideal Applications

• Compressor Outlets: Connecting the main discharge of rotary screw compressors to the primary header.
• Air Tank Connections: Connecting large vertical or horizontal receiver tanks to the distribution network.
• Dryer & Filter Banks: Interconnecting heavy-duty air treatment equipment where threaded fittings are impractical due to size.
• Butterfly Valves: Installing large section isolation valves that utilize flange mounts.
