REXNORD SMALL AXIAL FANS ( AC series )

REXNORD AC AXIAL FANS

Advantage: Rated for a wide operating temperature range ( $-20^{\circ}\text{C}$ to $+70^{\circ}\text{C}$ for ball-bearing models).
Benefit: These fans can be mounted inside hot power conversion units or welding machines where standard consumer fans would fail due to melted housings or seized bearings.

Advantage: Built to meet international standards (UL, CE, CSA, TUV).
Benefit: For OEMs exporting machinery to Europe or the US, using Rexnord fans simplifies the safety certification process for the entire panel, as the cooling components are already pre-certified and Impedance Protected.

Advantage: Optimized aerodynamic blade pitch.
Benefit: They are designed to “push” air through dense components (like cable bundles or heat sinks) where air resistance is high. They don’t just spin; they move air with force.

Advantage: Shielded motor design with high dielectric strength (AC $1500\text{V}$ for 1 minute).
Benefit: They produce minimal electrical noise, making them safe for use near sensitive PLC controllers or medical instrumentation without causing signal glitches.

Aluminum Die-Cast Housing: Unlike cheaper plastic-frame fans, Rexnord uses high-grade aluminum.¹ This acts as a secondary heat sink for the motor and provides rigid protection against physical damage or mounting stress.
Impeller Materials: * Plastic (Standard): High-strength PBT (Polybutylene Terephthalate) or Glass-filled Nylon 66, which is flame-retardant (UL94V-0).
- Metal (MB Series): Painted Mild Steel blades for high-ambient heat or heavy-duty environments.

Ball Bearing (B Series): Utilizes high-precision, double-shielded ball bearings.³ Ideal for $24/7$ duty cycles and high-temperature environments (up to $70^{\circ}\text{C}$ ).
Sleeve Bearing (S/A Series): Cost-effective for intermittent use or cooler environments, featuring self-lubricating sintered bronze bushings.

Motor Design: Features a Shaded Pole motor for compact models ( $80\text{--}172\text{ mm}$ ) and Capacitor-run motors for larger, high-efficiency versions ( $200\text{ mm}$ +).
Connections: * “T” (Terminal): Features two metal pins for quick-disconnect power plugs.
- “W” (Lead Wire): Pre-soldered $300\text{ mm}$ (approx.) wires for hard-wiring into a circuit.
