DURABILITY
Ball bearings with heat-resistant grease are used in the bearings, minimizing stress on the bearings (example, from vibration, thrust load, and heat) and lightening the load. This ideal structure makes the bearings highly durable. In particular, the all-steel outer rotor series can be relied upon to perform with a durability no other company's products offer.

HIGH PERFORMANCE/LOW NOISE
The form of the blades and frame were specially designed for higher blade efficiency: high air flow with low noise. There are also ultra low noise models with middle and low speeds.

WIDE RANGE OF Environmental Temperature
As specially selected high quality materials used in the ball bearings and other parts these fans can be used in ambient temperatures from -30°C to +70°C.

MINIMAL MAGNETIC FLUX LEAKAGE
The all-steel outer rotor series has the rotor surrounded by a metal case to reduce leakage of magnetic flux. Leakage is especially small on the air intake side.

CHOICE OF INSTALLATION POSITIONS
Possible installation positions include level, perpendicular, or diagonal, on the intake side or the exhaust side.

SAFE (IMPEDANCE PROTECTED)
Fire-retardant insulation materials are used. Also, the fans are designed so that even if the rotating parts lock, the windings will not burn out. Thus, these fans offer an extremely high level of safety.
