14" Commercial Refrigeration Fan Blade – CCW, 27° Pitch, 4 Blade

14" Commercial Refrigeration Fan Blade – CCW Rotation, 27° Pitch, 4 Blades

This 14-inch commercial refrigeration fan blade is a four-blade replacement designed for compatible refrigeration and cooling-system fan assemblies. The blade is identified by its counterclockwise (CCW) rotation, 27-degree pitch, and 4-blade configuration.

Correct fan-blade selection is critical to refrigeration airflow. A blade with the wrong diameter, pitch, rotation, hub configuration, or mounting arrangement can produce incorrect airflow, excessive motor load, vibration, poor condenser or evaporator performance, and reduced equipment efficiency.

Before ordering, compare the original fan blade carefully and verify the 14" diameter, CCW rotation, 27° pitch, four-blade design, hub configuration, shaft mounting, and intended airflow direction.

Product Specifications

• Part Type: Commercial Refrigeration Fan Blade
• Blade Diameter: 14"
• Rotation: Counterclockwise (CCW)
• Pitch: 27 Degrees
• Number of Blades: 4
• Application: Commercial Refrigeration / Cooling Equipment
• Function: Refrigeration Airflow

What This 14" Fan Blade Does

The fan blade mounts to the applicable fan motor and moves air through the refrigeration system. Depending on the equipment configuration, the blade may support condenser airflow, evaporator airflow, or another cooling-air application.

Proper fan-blade operation helps support:

• Consistent refrigeration airflow
• Proper heat transfer
• Normal condenser or evaporator performance
• Reduced excessive motor load
• Stable refrigeration-system operation
• Consistent equipment temperatures
• Dependable commercial refrigeration performance

14-Inch Diameter

This replacement fan blade is identified as 14 inches in diameter. Diameter must match the original fan assembly closely enough to provide proper shroud clearance and airflow.

A blade that is too large may contact the guard or shroud. A blade that is too small may not provide the airflow required by the equipment.

Counterclockwise Rotation

This blade is identified for CCW rotation. Rotation is a critical replacement characteristic because installing a blade with the wrong rotation can move air in the wrong direction or provide significantly reduced airflow.

Always compare the original blade and confirm how the manufacturer defines rotation. Fan-blade rotation may be specified from a particular viewing side of the motor or blade assembly, so the original equipment configuration should be used as the final reference.

27-Degree Blade Pitch

The blade is identified with a 27-degree pitch. Blade pitch influences how much air the fan moves and how much load is placed on the motor.

Changing pitch can affect:

• Airflow volume
• Motor amperage
• Motor temperature
• Static-pressure performance
• Refrigeration heat transfer
• Noise and vibration

Do not substitute a different blade pitch solely because the diameter and number of blades are the same.

Four-Blade Configuration

This fan uses a four-blade design. The number of blades is another important airflow and motor-load characteristic and should match the intended equipment application.

Common Signs of a Damaged Fan Blade

Qualified commercial refrigeration technicians may inspect the fan blade when troubleshooting conditions such as:

• Reduced airflow
• Fan vibration
• Abnormal fan noise
• Blade rubbing against the shroud or guard
• Cracked blade
• Bent blade
• Loose blade on the motor shaft
• Uneven blade tracking
• Equipment running warmer than expected
• Motor overheating
• Fan assembly repeatedly going out of balance

These symptoms do not automatically confirm blade failure. Fan-motor bearings, motor mounting, guards, shrouds, ice buildup, debris, wiring, and refrigeration-system conditions can produce similar symptoms.

Inspect the Fan Motor Before Replacing the Blade

A damaged fan blade can sometimes be the result of a motor or mounting problem. Before installing a replacement blade, inspect the fan motor for:

• Excessive shaft play
• Worn bearings
• Bent motor shaft
• Loose mounting hardware
• Excessive vibration
• Incorrect motor rotation
• Motor overheating

A motor with excessive shaft movement can cause the replacement blade to wobble, contact surrounding components, or fail prematurely.

Check Shroud & Guard Clearance

After installation, the blade must rotate freely without contacting the fan guard, shroud, coil, wiring, or surrounding refrigeration components.

Verify:

• Blade is centered correctly
• Clearance is consistent around the full rotation
• No blade tips are bent
• Hub is securely mounted
• Blade rotates freely by hand with power disconnected

Airflow Direction Matters

Correct blade rotation does not by itself guarantee correct airflow. Blade pitch, mounting orientation, motor rotation, and installation side all affect the final direction of air movement.

Before returning the equipment to service, verify that air is moving in the same intended direction as the original installation.

Technician Checks Before Ordering

Before ordering this fan blade, verify:

• 14" blade diameter
• CCW rotation
• 27° blade pitch
• 4-blade configuration
• Center hub design
• Shaft diameter / mounting arrangement
• Blade offset
• Motor rotation
• Required airflow direction
• Fan-shroud clearance
• Original equipment model
• Original fan-blade markings where available

Do not order by diameter alone. A 14-inch fan blade with the wrong pitch, rotation, hub, or mounting arrangement may not operate correctly.

Commercial Refrigeration Applications

This type of fan blade may be used in compatible commercial refrigeration and cooling equipment found in:

• Restaurants
• Commercial kitchens
• Supermarkets
• Convenience stores
• Walk-in coolers
• Walk-in freezers
• Reach-in refrigeration
• Cold-storage equipment
• Foodservice facilities
• Commercial refrigeration systems

Installation & Service Notes

Disconnect electrical power before servicing any refrigeration fan assembly.

Before removing the original blade, document:

• Blade orientation
• Hub position
• Shaft engagement
• Motor rotation
• Airflow direction
• Clearance from surrounding components

Compare the replacement blade with the original before installation.

After installation, verify that the blade rotates freely, runs without excessive vibration, clears the guard and shroud, and moves air in the proper direction.

Why Exact Fan Blade Specifications Matter

Commercial refrigeration fan blades can look nearly identical while having different diameters, pitches, rotations, blade counts, offsets, and hub configurations.

For this replacement, the important verified characteristics are 14" diameter, CCW rotation, 27° pitch, and four blades. The original hub and mounting configuration should also be matched before ordering.

Frequently Asked Questions

What size is this fan blade?

This fan blade is identified as 14 inches in diameter.

What rotation is this fan blade?

It is identified as a counterclockwise (CCW) fan blade. Confirm the original equipment's viewing reference for rotation before ordering.

What is the pitch of this fan blade?

The blade is identified with a 27-degree pitch.

How many blades does it have?

This fan blade uses a four-blade configuration.

Can I replace another 14-inch fan blade with this one?

Not based on diameter alone. Rotation, pitch, number of blades, hub design, shaft mounting, offset, and airflow direction must also be compatible.

Can the wrong fan blade make a motor overheat?

Yes. Incorrect pitch, diameter, blade count, or mechanical installation can increase motor load and contribute to overheating.

Can a bent blade cause vibration?

Yes. A bent, cracked, or unbalanced fan blade can produce vibration and place additional stress on the motor bearings.

Should I inspect the motor when replacing the blade?

Yes. Check shaft play, motor bearings, mounting, rotation, and condition before installing the replacement blade.

How do I confirm this is the correct fan blade?

Verify the 14" diameter, CCW rotation, 27° pitch, four-blade configuration, hub design, shaft mounting, motor rotation, and required airflow direction against the original blade.

Is professional installation recommended?

Qualified commercial refrigeration personnel can verify motor rotation, blade mounting, clearance, airflow direction, and refrigeration-system operation during replacement.
