Campbell Hausfeld WL611700AJ Air Compressor 115 mm (4.5 in) x 31 mm (1.25 in)

An updated version of the design incorporates a backward curved blade profile to improve airflow efficiency and cooling performance compared to the original fan geometry. The revised blade orientation reduces turbulence and improves air movement across the motor during operation.

PETG Isn't strong enough with the current design.

This summary describes the setup and specifications for a 3D printed replacement motor cooling fan designed for the Campbell Hausfeld WL611700AJ air compressor. The fan was modeled to replicate the original radial cooling fan geometry used to move air across the electric motor for thermal management during compressor operation.

The replacement component was created from measurements of the original fan and reproduced as a parametric 3D model suitable for additive manufacturing.

Component Description

The component is a radial cooling fan with vertical blades that mounts directly to the compressor motor shaft. When the motor rotates, the fan pulls ambient air through the motor housing and pushes it outward across the motor body to dissipate heat.

The design matches the original configuration used on the Campbell Hausfeld unit and maintains similar airflow characteristics.

Material Recommendation

Because the fan operates near the compressor motor where temperatures may exceed 140 F (60 C), higher temperature filaments are recommended.

Preferred materials

ABS
ASA
Nylon

Avoid PLA due to low heat resistance and potential deformation.
