The ARO Provenair Series is a family of NFPA-repairable and interchangeable pneumatic cylinders designed for rugged industrial applications. Available in both stainless steel (SN Series) and aluminum (AN Series) constructions, these cylinders deliver exceptional durability and corrosion resistance. All external components are manufactured from series 300 stainless steel, including end caps, tie rods, piston rods, and mounts, with a 316 stainless steel barrel providing superior corrosion protection[citation:1].

Built to the latest NFPA specifications, the Provenair cylinder combines tie-rod construction with precision-machined bearing bronze bushings, ensuring reliable operation and long service life in demanding environments[citation:1]. The flexible model numbering system allows OEM and MRO customers to order exactly the options needed for any application without requiring special or modified cylinders[citation:3].

Key Features & Advantages

Stainless Steel Corrosion Resistance: The SN Series Provenair cylinder features all-stainless steel external components manufactured from 303/304 stainless steel for end caps, tie rods, piston rods, and mounts, with a 316 stainless steel barrel[citation:1]. This construction ensures exceptional resistance to corrosive environments, making the cylinder ideal for food processing, pharmaceutical, marine, and outdoor applications where moisture and chemicals are present.

NFPA Interchangeability and Repairability: The Provenair cylinder conforms to NFPA specifications, ensuring dimensional interchangeability with other NFPA-compliant cylinders from major manufacturers[citation:3][citation:4]. The repairable design allows field service using readily available seal kits, extending product life and reducing replacement costs. Factory-lubricated with washout-proof grease, these cylinders operate reliably without external lubrication[citation:3].

High Pressure Ratings: The Provenair cylinder is pressure-rated to 250 PSI for pneumatic applications and 400 PSI for hydraulic (non-shock) service[citation:1]. Output forces reach up to 19,635 lbs with a 10" bore operating at 250 PSI, providing ample power for demanding industrial applications[citation:3].

Wide Bore Size Range: Stainless steel Provenair cylinders are available in bore sizes from 1-1/2", 2", 2-1/2", 3-1/4", 4", 5", 6", and 8"[citation:1]. The aluminum AN Series offers additional options including 10" bore sizes for higher force requirements[citation:3]. This broad selection allows precise matching of cylinder capacity to application needs.

Versatile Mounting Options: The stainless steel SN Series offers 10 standard mount configurations, while the aluminum AN Series provides 15 NFPA mounting styles[citation:1][citation:3]. Factory-installed mounts save time and labor by eliminating the extra parts associated with mounting kits, and optional rotated ports provide additional installation flexibility[citation:3].

Tie-Rod Construction for Durability: Tie-bolt construction eliminates rod binding and tie-rod torque problems on Series AN cylinders up to 4" bore[citation:3]. Larger bore sizes (5" through 10") feature pre-stressed steel tie rods for enhanced strength and rigidity. Rugged thick-walled tubes resist denting, ensuring long-term structural integrity even in harsh industrial environments[citation:3].

Optional Features for Special Applications: The Provenair cylinder can be customized with optional 303 stainless steel piston rods for enhanced corrosion resistance[citation:3]. Oversized rods provide extra column strength for long-stroke applications, while optional slippery seals enhance smooth operation and are self-lubricating. For high-temperature environments, Viton seals are available for operation up to 300°F (149°C)[citation:3].

Wide Temperature Range: Standard operating temperature ranges from 0°F to 185°F (-18°C to 82°C), accommodating most industrial environments[citation:3]. Optional high-temperature seals extend capability to 300°F (149°C) for specialized applications such as foundries, heat treating, and high-temperature processing equipment.

Industry-Leading 5-Year Warranty: All ARO pneumatic cylinders are backed by a comprehensive 5-year warranty, reflecting the confidence in product quality and reliability[citation:4]. This warranty provides assurance for OEMs and end-users seeking long-term, trouble-free operation.

Technical Specifications Summary

The Provenair cylinder operates as a double-acting, single-rod cylinder with standard operating temperature of 0°F to 185°F (-18°C to 82°C). Bearing systems utilize precision-machined bearing bronze for smooth operation and extended service life[citation:1]. Factory-lubricated with washout-proof grease eliminates the need for external lubrication in most applications. Optional magnetic pistons are available for position sensing applications.
