Marvair 40045A Motor

Marvair 40045A Motor

The Marvair 40045A Motor is the direct OEM replacement motor for the legacy 40045 part number, specifically engineered for Marvair ComPac series wall-mounted air conditioners and ventilation units. This 1/5 HP blower motor operates on a 208-230V, single-phase power supply at a constant 1075 RPM. As a veteran in the field, you know these indoor blower motors are critical for maintaining the static pressure required in telecommunications shelters and modular classrooms where Marvair units are standard. This PSC (Permanent Split Capacitor) motor features a durable rolled steel shell and a 48Y frame size, built to handle the continuous duty cycles of mission-critical HVACR cooling.

Marvair 40045A Technical Specifications:

  • Model Number: 40045A (Updated from 40045)
  • Horsepower: 1/5 HP
  • Voltage: 208-230V (1-Phase)
  • Full Load Amps: Typically 1.1A - 1.3A (refer to nameplate)
  • Speed: 1075 RPM
  • Enclosure: Open Air-Over (OAO) for optimal thermal management
  • Rotation: Reversible or designated CWLE/CCWLE (verify lead configuration)
  • Bearings: Permanently lubricated sleeve or ball bearings for maintenance-free operation

Key Benefits for Contractors:

  • Direct Drop-In Fit: Eliminates field modifications when replacing the older 40045 series in Marvair ComPac I and II units.
  • Optimized Airflow: Precision-balanced at 1075 RPM to ensure the evaporator blower fan maintains proper CFM across the coil.
  • Enhanced Reliability: Engineered with high-grade insulation to withstand the internal heat gains of electronic equipment shelters.
  • Quiet Operation: Low-vibration design reduces acoustic noise transfer through the ductwork in classroom environments.

Common HVACR Questions:

What capacitor is required for the Marvair 40045A?
Most setups for this 1/5 HP motor utilize a 5 MFD / 370V run capacitor. Always check the motor nameplate for the specific microfarad rating before installation.

Can this motor be used in ComPac II units with an economizer?
Yes, the 40045A is the standard indoor fan motor for various Marvair wall-mount configurations, including those equipped with factory-installed economizers, provided the signal matches the single-speed PSC requirements.

How do I verify if I need the 40045A or the 40055A?
The 40045A is a 1/5 HP motor, whereas the 40055A is typically a 1/3 HP version. Match the horsepower and the RPM (1075) to your existing unit's data plate to ensure proper torque for the blower wheel.
