¡á SEC.1.  General Features

 

° Advanced Technology We have

1. Foil Air Bearing Technology

2. High Speed BLDC Motor & Motor Drive

    (Inverter) Technology

3. Impeller Precise Casting Technology

 

Turbo blower, which is composed of a high speed brushless DC motor with the efficiency of 95%, air foil bearings, and the other many components, have semi-permanent life span and the total efficiency is better than 30 % compared with that of roots blower.

 

° The general features are as follows :

1.

Turbo blower, designed by three-dimensional aerodynamic analysis, have outstanding thermodynamic efficiency.

2.

Use of air bearing does not allow any mechanical friction loss.

3.

The combination of the motor and inverter economically controls electric power according to load.

4.

Turbo blower can be semi-permanently used with very simple maintenance.

5.

No mechanical contact allows very low noise level below 75¢¦80dB@1m at high-pitched tone.

6.

No noise and vibration at low frequency makes any absorbing facility unnecessary.

7.

No lubrication system can supply clean air containing no oil.

8.

Simple, small, and light weight structure allows easy transportation and installation (adjustable I-bolt supporting facility shall only be applied without any special/regular foundation works).

9.

Intrinsic micro-processor and LAN help remote computer control.

 

¡á SEC.2.  Advanced Technology we have.

 

1. Foil Air Bearing Technology

Hydrodynamic foil type air bearing, which floats itself by lifting force induced by pressure gradient around the rotating shaft, doesn't require any mechanical lubrication. This fact makes various complicated components unnecessary such as oil bearing, seal, oil filter, cooler, etc., used for the existing high speed turbomachine. So the blowing system becomes simple, and the oil-free air can be supplied in true meaning. Furthermore, system without mechanical lubrication promotes system efficiency about 3 %.

 

 

 

2. High Speed BLDC Motor & Motor Drive (Inverter) Technology

A motor of BLDC(Brushless Direct Current) type with large capacity, and without any physical contact between rotor and stator, offers high efficiency of 95%.

For this reason, the motor has low noise - no vibration characteristics, and very long life span. The permanent magnets especially designed for the stability at high temperature make cooling load minimize.

 

3. Impeller Precise Casting Technology

Impeller is made of SUS 630 by precision die-casting with lost-wax method, and its blade shape is determined by three dimensional optimal design technique for the highest efficiency.

Also, shrink fitting is used for the connection with the rotor of motor.
