N12.3 Line Drawing 

123 Nautilair Combustion Blower High Energy 275H RevDeveloped to address customer needs for greater power from the same blower size, the Nautilair 12.3" High Energy Blower builds upon the foundation of its predecessor, the original Nautilair 12.3” blower, with targeted enhancements.

  • Replaced the Ferrite magnet with a Neodymium magnet
  • Upgraded the 20-blade plastic cooling fan with an eight-blade aluminum fan 
  • Offers an optional impact-resistant plastic enclosure with exhaust tube 

These new design features minimize demagnetization risks from external factors like magnetic fields or high temperatures. The backward curved cooling fan with significantly less blades reduces noise and improves motor efficiency, without compromising motor cooling. The option to utilize an exhaust tube can prevent cooling air recirculation which allows for lowering motor operating temperatures ensuring long motor life.
