Lau 60555901 3-Blade 18-inch Clockwise Free-Air Propeller is a replacement fan blade designed to restore air movement in compatible HVAC, ventilation, and equipment cooling assemblies.

The 18-inch diameter, 3-blade design, and clockwise rotation support proper free-air circulation when matched to the original equipment requirements.

This propeller helps maintain cooling performance, ventilation efficiency, and reliable system operation by moving air across the required equipment area. Confirm blade diameter, rotation direction, hub configuration, and motor compatibility before installation.
 

Frequently Asked Questions
 

• What is the Lau 60555901 used for?

The Lau 60555901 is used as a replacement 3-blade propeller for compatible HVAC, ventilation, and equipment cooling applications that require an 18-inch clockwise free-air fan blade.

• What does clockwise rotation mean?

• Is this a complete fan assembly?

No. The Lau 60555901 is a propeller blade component only. It is intended for use with a compatible motor, hub, guard, and fan assembly.

• What should be checked before ordering this propeller?

Confirm the original blade diameter, blade count, rotation direction, hub configuration, motor compatibility, and equipment requirements before ordering.

• Where is this propeller commonly used?

This propeller may be used in compatible HVAC equipment, ventilation systems, condenser-style air movement applications, and other free-air cooling assemblies where the specifications match.

• Why is blade rotation important?

Incorrect blade rotation can reduce airflow and may affect equipment cooling or ventilation performance. The replacement propeller should match the required clockwise rotation of the original part.

• Does this propeller help improve airflow?

When correctly matched and installed, the Lau 60555901 helps restore proper air movement in compatible fan assemblies by replacing a damaged, worn, or incorrect propeller.
