Technical Overview

The Omron R87F-A4A85HP is a highly reliable industrial-grade AC axial fan engineered for efficient heat dissipation in electronic enclosures and machinery. Measuring 80 x 80 x 38 mm, it features a rugged aluminum die-cast frame paired with durable glass polycarbonate blades for enhanced environmental resistance. Operating at 200 VAC, it utilizes a single-phase shading coil induction motor equipped with precision ball bearings to ensure an extended service life and low acoustic noise. Designed for high-speed performance, the fan delivers a maximum volumetric airflow of up to 0.9 m³/min, effectively minimizing thermal stress in enclosed control panels and power systems. Built-in impedance protection reliably prevents motor burnout during locked-rotor conditions, increasing overall operational safety.
