Dayton 23NU07 Replacement Blade 36 In 1 HP

SKU CH-4JPC-99BJC

36-inch aluminum propeller blade with five blades, 25 mm bore, 850 RPM and 1 hp rating for direct-drive HVAC applications

  • 36 inch propeller moves large air volumes efficiently
  • Five aluminium blades balance airflow and quiet operation
  • Direct drive at 850 RPM delivers consistent 1 hp performance
  • 25 mm bore fits Dayton 1YNW7 motor without adapters
  • Aluminium construction resists corrosion for long service life

Direct-drive 36-inch propeller

This five-blade aluminium propeller measures 36 inches in diameter and mounts on a 25-millimetre bore. It is rated for one horsepower at 850 RPM and connects directly to the motor shaft. Maintenance teams use it to restore airflow on compatible Dayton ventilators.

Red finish and matched bore

The red coating identifies the blade at a glance in crowded mechanical rooms. Its 25-millimetre bore matches the shaft on the 1YNW7 motor assembly without adapters. Direct-drive mounting removes belts, pulleys and alignment steps from the installation.

Aluminium construction for steady service

Five aluminium blades resist corrosion while keeping rotational mass low for quick start-up. The direct-drive hub transmits the full one horsepower without slippage. Installers should verify shaft diameter and rotation direction before fitting the blade.

Questions about this item

How often should the 36 in aluminum propeller blade be inspected for wear?

Inspect the 5-blade aluminum propeller at each scheduled shutdown; replace it if any blade shows cracks, corrosion or imbalance that could affect the 850 RPM direct-drive operation.

What is the first limit reached when the blade runs continuously at 850 RPM?

The 1 hp motor rating sets the sustained-load ceiling; exceeding it will trip the motor overload before the 25 mm bore or direct-drive hub shows distress.

How much noise and heat does the 36 in direct-drive blade add during all-day operation?

At 850 RPM the 5-blade aluminum propeller moves air with a steady broadband hum; motor heat stays within the 1 hp design envelope so no extra cooling is needed.
