Amtecs Force Vent Fan – Forced Ventilation for Inverter-Driven Motors, Frames 63–355 (Single & Three-Phase)
Amtecs Force Ventilation Units provide continuous, independent cooling for motors running on inverters (VFDs) or operating for long periods at low speed. By maintaining a steady airflow over the motor frame, these units prevent overheating, stabilise efficiency, and extend motor life in demanding duty cycles.
Key Specifications
Manufacturer: Amtecs
Product Type: Force Vent Fan (External Motor Cooling)
Compatible IEC Frames: 63, 71, 90, 100, 112, 132, 160, 180, 225, 250, 280, 315, 355
Supply Options: Single-Phase (230 VAC) or Three-Phase (415 VAC)
Use Case: Constant airflow independent of motor shaft speed
Mounting: Replaces/augments standard rear fan & cowl on IEC motors
Typical Pairing: VFD-controlled induction motors or motors with encoders
When to Use Forced Ventilation
- Motor is inverter-driven with variable speeds (VFD applications).
- Motor runs at ≤ 50% of rated speed for prolonged periods.
- Motor has reduced natural airflow (enclosures, tight installations, or frequent low-speed duty).
- Encoder or feedback device replaces the standard cooling fan.
How It Works
The force vent fan delivers constant cooling independent of shaft RPM. A dedicated power feed (230 VAC single-phase or 415 VAC three-phase) drives the auxiliary fan to maintain airflow over the motor’s external surfaces, ensuring stable temperatures across the entire operating range.
Features & Benefits
- ✅ Consistent cooling at any speed — protects windings during low-RPM operation.
- ✅ Improved efficiency & reliability — helps prevent thermal trips and derating.
- ✅ Wide frame coverage — fits IEC 63–355 motors.
- ✅ VFD-friendly — ideal for inverter or encoder-equipped motors.
- ✅ Easy retrofit — mounts to standard IEC rear fan cowls.
Selection Guide
Tell us: Motor brand & model, IEC frame size (63–355), shaft height/orientation, required supply (230 VAC single-phase or 415 VAC three-phase), and enclosure constraints. We’ll confirm correct fan size, cowl interface and airflow for your duty cycle.
Typical Applications
- Conveyors, packaging lines, mixers, pumps & fans
- Positioning/servo-like duties with encoders
- Processes requiring extended low-speed torque
- Enclosed or poorly ventilated installations
