GDSTIME GAA1238B 120×120×38 mm 110–120V AC Dual-Ball-Bearing Axial Cooling Fan, 50/60Hz, 2-Wire Connector

Condition: New, unused. No original retail box was ever present. The fan appears clean and unused, with factory label, wiring, connector, frame, and mounting holes intact.

Description

The GDSTIME GAA1238B is a heavy-duty AC axial cooling fan designed for ventilation and heat removal in electrical enclosures, industrial equipment, control cabinets, power electronics, server/network hardware, refrigeration controls, machinery, and other applications requiring continuous forced-air cooling.

The model uses a dual-ball-bearing motor assembly, which is generally preferred over sleeve-bearing construction for longer service life, higher-temperature operation, and installations where the fan may run for extended periods. The fan is rated for 110–120V AC, 50/60Hz, making it suitable for standard North American line-voltage applications.

Based on the model designation and the physical measurements shown in the photos, the fan is the common 120 × 120 × 38 mm industrial axial-fan format, approximately 4.7 × 4.7 × 1.5 inches.

Dimensions

The photographs with a measuring tape support the standard 12038 fan format:

• Width: approximately 120 mm / 4.7 in.
• Height: approximately 120 mm / 4.7 in.
• Depth: approximately 38 mm / 1.5 in.

The “1238” portion of model GAA1238B is consistent with the common industry convention for a roughly 120 mm square × 38 mm thick fan, although this should be treated as a practical identification convention rather than a formal manufacturer decoding statement.

Motor and Rotation Information

This fan contains an integrated AC motor and is not intended to be treated as a standalone shaft-output motor.

• Motor supply: 110–120V AC
• Phase: Single-phase AC appliance/fan application
• Frequency: 50/60Hz
• Bearing: Dual ball
• Speeds: Fixed-speed design unless externally controlled by compatible equipment
• Shaft: Internal fan rotor; no external shaft
• Motor Shaft Rotation: Not applicable in standard SE/LE motor format because this is an integrated axial fan assembly
• Airflow / Rotation Direction: Directional markings are molded into the housing; installation should follow the frame’s molded airflow/rotation arrows

Because the fan is a complete axial-air-moving assembly, conventional motor notation such as CCWSE/CWLE is not normally used for this product.

Features

• 110–120V AC operation
• 50/60Hz compatibility
• Dual-ball-bearing construction
• Standard 120 mm square industrial fan footprint
• Approx. 38 mm deep heavy-duty frame
• Two-wire line-voltage connection
• Preinstalled 2-pin connector
• Four-point mounting pattern
• High-strength molded frame
• Large axial impeller
• Suitable for continuous ventilation duty
• Directional rotation/airflow markings molded into frame
• Compact direct-mount design
• No external power supply required when connected to the proper 110–120V AC source

Applications

The GDSTIME GAA1238B is suitable for forced-air cooling in:

• Electrical control cabinets
• Automation enclosures
• PLC cabinets
• CNC machinery
• Industrial electronics
• Power supplies
• Audio amplifiers
• AV equipment
• Network cabinets
• Server enclosures
• Test equipment
• Laboratory equipment
• Refrigeration control panels
• HVAC electrical compartments
• Welding equipment
• Battery chargers
• Inverters
• UPS systems
• Power distribution equipment
• Telecom cabinets
• Arcade and gaming cabinets
• 3D-printer enclosures
• Laser equipment
• General machinery ventilation

HVAC and Refrigeration Uses

Within HVAC and refrigeration environments, this fan may be used where a 120V AC cabinet fan of matching physical dimensions and airflow characteristics is required, including:

• Equipment control compartments
• Refrigeration controllers
• Condensing-unit electrical sections
• Compressor control cabinets
• Heat-pump control boxes
• Commercial refrigeration panels
• Ventilated relay enclosures
• Electronic drive cabinets

It should not be substituted for a condenser or evaporator fan motor unless the original equipment specifically calls for this size and type of axial fan.

Electrical Connection

The fan uses two electrical leads terminated in a white two-pin connector.

Before installation, verify:

• Supply is 110–120V AC
• Frequency is compatible at 50 or 60Hz
• Connector mates correctly with the equipment harness
• Lead configuration matches the original fan
• Equipment is de-energized before connection
• Grounding and enclosure requirements comply with the host equipment design

This is a line-voltage AC fan, not a 12V, 24V, or 48V DC computer fan.

Cross-Referenced Models

The following are useful form-factor and application cross-references, but should not be assumed to be direct electrical replacements without checking connector, current draw, RPM, airflow, and mounting details:

• Connector style
• Mounting-hole spacing
• Airflow direction
• Rotation direction
• CFM
• RPM
• Current draw
• Noise level

Part of a Larger System

The GAA1238B is commonly used as a component in a larger thermal-management system consisting of:

Electrical enclosure → intake opening/filter → axial fan → internal electronics → exhaust opening/grille

It may also be installed with:

• Finger guards
• Wire fan guards
• Dust filters
• Foam filters
• Louvered vents
• Thermostatic fan controllers
• Equipment chassis
• Rack enclosures
• Electrical cabinet cutouts

A fan guard should generally be used where the rotating blades may be accessible after installation.

Advantages

• Standard industrial form factor
• Operates directly from 110–120V AC
• Dual-ball bearings are suited to extended operating periods
• Compact size for cabinet mounting
• Simple two-wire connection
• Widely used mounting format
• Suitable for electrical and industrial cooling
• Does not require a separate low-voltage DC power supply

Important Replacement Considerations

A fan with the same physical dimensions is not necessarily electrically or thermally equivalent. Before substituting this model, confirm:

• Voltage
• Frequency
• Current
• Wattage
• CFM
• Static pressure
• RPM
• Airflow direction
• Connector
• Mounting-hole spacing
• Maximum ambient temperature

Because the label shown does not list CFM, RPM, current, or wattage, those specifications should not be assumed when matching it to mission-critical cooling equipment.
