Air bearing
Non-contact bearings that utilize fluid dynamic pressure that occurs automatically between motor and foil rotating at a high speed, provide a structure with no friction at all during the operation, which is developed with our unique technology.
A non-contact bearing, which supports the load of the rotating body by using a force of an air around the shaft rotating at a high speed, compressed by the wedge effect.
The air bearing type of mcb-Series is non-lube and non-contact, which does not use a lubrication oil, while not causing the malfunction and making the maintenance convenient due to the simple system structure. It maintains the highest efficiency by minimizing the power loss and provides a stable and long life with non-vibratory and noiseless environmentally friendly air bearings.

Data Sheet
Understanding the performance curves of the TURBO BLOWER
The upper and lower limits of pressure/flow rate are applied to each model
Able to operate within the surge point and the overheat line of the performance map
Inhalation temperature; affected by the humidity
Change in flow rate at the change of discharge pressure. (If the pressure rises, the flow rate decreases; inversely proportional)
Surge is where the discharging air flows backward, causing the noise/vibration, while pressure and flow rate is fluctuating rapidly.
