Finding the right 30 inch fan blade means prioritizing fit, rotation, and application. This guide highlights five reliable 30″ blades suitable for commercial HVAC, industrial ventilation, and equipment cooling. Each product is evaluated for who benefits most, with practical pros, limits, and fit notes to help you choose confidently.
| Product | Best For | Key Fit Note |
|---|---|---|
| PRO SOURCE Commercial Fan Blade | Large-scale HVAC and industrial ducts | 15mm bore; clockwise rotation |
| FAN04082 / FAN-4082 (Trane OEM) | Retrofits in RTACs and air cooled chillers | Common OEM replacements with 3 blades |
| AAON 9001637 Style (Generic) | AAON condenser systems and equivalents | 30″ blade, 1/2″ bore, clockwise |
| GLOBAL INDUSTRIES 293102 | Washdown or moisture-prone environments | Silver blade, washdown-ready |
| HEATCRAFT 22900401 | Standard 30″ setups with CW rotation | 30″ diameter, 26 degree pitch |
Note on compatibility: blade bore size, pitch, and rotation direction affect fit and airflow. Always verify motor shaft size and mounting pattern before purchasing. The selections below emphasize clear applicability to common 30″ systems and provide practical guidance for choosing the best match to your equipment and maintenance needs.
PRO SOURCE Commercial Fan Blade

Features: Commercial grade with a 30-inch diameter built for industrial use. The blade is designed for clockwise rotation to optimize airflow in large ventilation systems and features a precise 15mm bore for secure motor mounting. Best for: facilities that require robust, long-lasting blades with consistent airflow in high-capacity exhaust or intake paths. Limitation: suited for clockwise rotation; verify your system’s rotation direction before replacing.
FAN04082 / FAN-4082 OEM Blade

Features: OEM 3-blade fan blade with a common 27-degree pitch, used in RTACs and similar air-cooled chillers. Best for: replacing specific OEM blades when the goal is direct compatibility with existing motors and housings. Limitation: blade fits are often model-specific; confirm exact compatibility with your unit’s part numbers.
AAON 9001637 Style Fan Blade

Features: Fits AAON 9001637 condenser blades with a 30″ diameter, 3 blades, and clockwise rotation. Best for: systems that mirror AAON condenser configurations requiring a standard 30″ blade replacement. Limitation: Bore size and exact blade geometry must match your existing hardware for secure mounting.
GLOBAL INDUSTRIES 293102 Blade

Features: Replacement blade designed for washdown fans, with a silver finish. Best for: environments where cleaning and corrosion resistance alongside washdown capability is important. Limitation: may not be suitable for non-washdown systems or blades with different pitch specs.
HEATCRAFT 22900401 Blade

Features: 30-inch diameter with a 26-degree pitch and clockwise rotation. Best for: standard 30″ fan assemblies needing reliable performance with moderate blade pitch. Limitation: pitch and rotation orientation should match the existing system to avoid airflow inefficiencies.
Buying Guide
What to check before buying a 30 inch fan blade: blade diameter, bore size, and mounting pattern. If your motor uses a 15mm or 1/2″ bore, confirm compatibility. Consider blade pitch to match airflow needs; higher pitch increases air displacement but may require more motor power. Rotation direction matters for airflow path—clockwise blades suit certain duct configurations and ventilation layouts. Environmental conditions—washdown, humidity, and corrosive exposure—affect blade material choice. With replacement blades, verify OEM compatibility when possible to avoid mounting or balance issues.
Installation considerations
Ensure the driver motor and hub alignment are correct. Use appropriate fasteners and safety practices for high-velocity blades. For washdown or corrosive environments, select blades with material and finish suited for moisture resistance. When replacing a blade, inspect the entire fan assembly for wear patterns to prevent imbalance and vibration after installation.
When to choose each option
- Best for general commercial HVAC: PRO SOURCE Blade and HEATCRAFT Blade.
- Better for OEM-specific replacements: Trane FAN-4082 and AAON style blade.
- Choose Global Industries for washdown environments where corrosion resistance is a priority.
FAQ
- What diameter is the blade? All listed blades are 30 inches in diameter.
- Which blade is best for clockwise rotation? PRO SOURCE, AAON style, HEATCRAFT, and many OEM blades are CW; verify your unit’s rotation.
- Do I need a specific bore size? Yes. Bore size (for example, 15mm or 1/2″) must match your motor shaft; incorrect bore prevents secure mounting.
- Are all blades interchangeable? Not necessarily. Substitutes require matching mounting style, pitch, and rotation to maintain airflow and balance.
