Prevost FRL Square Profile

Prevost FRL Assembly for PPS (Square Aluminum Pipe)

Direct-Mount Air Treatment for the Ultimate Aluminum Pipe System

Seamlessly integrate high-performance air treatment directly into your ring main with the Prevost FRL for PPS. Designed exclusively for the Prevost Piping System (PPS)—the industry-leading square-profile aluminum pipe—this assembly eliminates the need for complex drop legs, threaded adapters, and wall brackets.

Using the innovative PPS Direct Flange, this unit bolts directly onto the flat face of the square aluminum pipe. This creates a clean, rigid, and incredibly fast-to-install air drop that taps vertically or horizontally straight from your main distribution line. Whether you need a simple Filter-Regulator (FR) or a complete Filter-Regulator-Lubricator (FRL) station, this system ensures your air is treated exactly where it leaves the network, maximizing flow efficiency and minimizing leak points.

Key Features & Benefits

• Direct-to-Pipe Mounting: Bypass traditional threaded pipe nipples and wall anchors. The unit attaches directly to the flat surface of the PPS aluminum pipe using the specialized flange interface.
• Leak-Free Integrity: The direct flange connection utilizes an O-ring seal compressed against the pipe, eliminating the risk of leaks common with tapered thread connections.
• Rapid Installation: Drastically reduces labor time. Simply drill the pipe using the PPS drilling jig, mount the flange, and bolt on the FRL unit. No heavy pipe wrenching required.
• Streamlined Aesthetics: Creates a modern, professional look for your facility with no “spaghetti piping” or hanging brackets cluttering the columns.
• Full ALTO Performance: Available with all standard ALTO features, including high-efficiency 25µm filtration, precise pressure regulation, and optional lubrication.¹
• Modular Versatility: Compatible with all ALTO modules (Shut-Off Valves, Soft Starts, Diverter Blocks) to build the exact station you need directly on the drop.
