PPS Technical Manual – Compressed air network

Enter the Prevost Piping System (PPS): a 100% aluminum, modular solution designed for efficiency, safety, and longevity. Based on the technical manual, here is a summary of why PPS is the superior choice for modern air networks.

1. 100% Aluminum Construction

The core of the PPS system is its construction. Unlike traditional steel or plastic pipes, PPS uses extruded aluminum (Alloy EN AW 6063 T6).

• Corrosion-Free: Aluminum does not rust, ensuring that the air supply remains clean and free of particulate contamination.
• Lightweight & Strong: The pipes are light enough to be handled by one person but robust enough to withstand impact and high pressure.
• Smooth Interior: The internal surface is perfectly smooth, which minimizes friction and results in low pressure loss and consistent flow rates.

2. The “PPS Grip Concept”: Leak-Free & Secure

One of the standout features is the PPS Grip Concept used in the fittings.

• How it works: A stainless steel ring with teeth penetrates the aluminum pipe to lock it securely in place.
• The Seal: A newly designed, lubricated nitrile seal with two lobes ensures a 100% leak-free connection, even under harsh conditions or misalignment.
• Easy Assembly: Installation is fast—simply push the pipe into the fitting and tighten. There is no welding, gluing, or complex disassembly required.

3. Safety & Compliance

Prevost prioritizes safety, meeting strict international standards:

• Pressure & Temp: The system is rated for operating pressures up to 16 bar (232 psi) and temperatures from -20°C to +80°C (-4°F to +176°F).
• Fire & Explosions: The system is fire retardant (EN 13501-1) and ATEX certified, meaning it is safe for use in potentially explosive environments (Zones 1, 2, 21, and 22).
• Markings: Pipes are color-coded for safety—Blue for compressed air, Grey for vacuum, and Green for inert gases (Nitrogen).

4. Smart Installation & Design

The document outlines best practices for a high-efficiency setup:

• The Loop: Install the main line in a loop to maintain constant pressure.
• The Drop: Use Tapping Flanges to create “drops” for workstations. These flanges pull dry air from the side of the pipe rather than the bottom, preventing condensate from reaching your tools.
• Expansion Ready: Aluminum expands with heat. The manual details how to calculate expansion and recommends using expansion kits or flexible hoses for long straight runs (over 50m) to prevent buckling.

5. A Complete Ecosystem

PPS isn’t just pipes; it’s a full ecosystem that includes:

• CC Concept: Compact connection fittings that save space in compressor rooms.
• Pneumatic Valves: Remote-controlled valves that can shut off air flow in an emergency or via a timer to save energy.
• Air Treatment: From cyclone separators to sub-micron filtration, ensuring the air reaching your tools is 99.99% clean.

Conclusion

Whether you are building a new facility or retrofitting an old one, the Prevost Piping System offers a “connected to innovation” solution. It eliminates the headaches of rust, leaks, and pressure drops, backed by a 10-year guarantee.
