Frame size and air-moving duty
The R87F-A4A15HP is Omron's R87F AC axial fan in the plastic-blade series, built around a single-phase shading coil induction motor (2-pole, open type) — the standard shaded-pole construction that gives long-life continuous duty in cabinet cooling without a run capacitor to fail. It drops into frame size 1 (120 × 120) with a 38 mm die-cast frame thickness, so the fan replaces the standard 120 mm cabinet cutout without rework on the panel wall or the mounting hole pattern.
Supply, speed, and wiring
Supply is 200 VAC (A4 in the R87F code) with a high-speed rotor — the right pick when the cabinet heat load needs aggressive airflow rather than the quieter low-speed variant, and the right voltage when the cabinet is fed from a 200 V distribution common to Japanese-spec machine panels. Termination is via terminals (P suffix) rather than lead wires, so the installer lands the supply conductors on screw/tab terminals inside the fan body — useful when the fan sits on a swing-out panel and a pluggable lead would bind the hinge.
Lifecycle and supply posture
Independent distribution stocks and quotes this code against an RFQ; volume pricing and current lead time are confirmed at quote time, and the same part is also surfaced as the dash-formatted R87F-A4A15-HP — identical build, only the suffix separator differs.
