Buying Guide
What to check before buying an 18 inch condenser blade
- Blade count: Three blades deliver smooth airflow; four blades can improve static pressure but may alter noise and airflow characteristics. Choose based on your condenser’s original spec.
- Bore size: Most blades use a 1/2″ bore. Verify bore on your motor shaft to avoid mounting issues.
- Rotation direction: CCW vs CW matters for airflow direction. Match the motor’s rotation to prevent reduced cooling or rubbing.
- Brand vs universal: Brand-specific blades guarantee compatibility with model numbers; universal blades offer flexibility but require careful verification of hub alignment and rotation.
