About the product


B-TOHIN machine (jiangsu) co., LTD., the foreign capital enterprise, was founded in 1994, the company has passed the pass the quality management system certification and | SO14001 environmental management system certification, and was identified as high-tech enterprises in jiangsu province, China famous trademark, brand-name products in jiangsu province, jiangsu province energy saving air power equipment engineering technology research center, a famous trademark in jiangsu province, environmental protection product certification, and won several national patents and national torch project.I have been awarded the brand title of Chinese water network user satisfaction for many years.


ATB series air suspension bearing high speed centrifugal blower is our company in South Korea production, complete machine.The product of the mouth adopts air suspension bearing, combined with precision casting impeller, super high speed and high efficiency motor,a high efficiency, energy-saving and environment-friendly high speed centrifugal blower made by international famous inverter technology.


Key Techonogy


1. Air Foil bearing


Air foil bearing is lubricated by air buoyancy. The use of air instead of lubricant can realize operation under higher temperature and speed. The advantages of air foil bearing structure include flexible start-up, low-cost operation, no mechanical friction, no need for lubrication oil, no vibration, lower noise and long service life (semi-permanent).

3.High Speed Motor


Adopt motor of high-efficiency up to 95%, of which the speed can be controlled precisely. The motor is of minimum usable design, fast speed and air cooling type to achieve high efficiency. Air cooling is more reliable than water cooling type, because it provides easier maintenance and promises safer operation.




4. Inverter & PLC

Inverter PLC

Adopt the international famous brand Japan YASKAWA inverter. The motor can be started up with a small current so as to cut down the investment on electricity and electric cable. Featured of low noise, high-efficiency, soft-start type and digital control efficiency no less than 96%, the inverter is stable and reliable in operation and can response to rapid load change very fast.





Adopt the programmable logic controller (PLC) of international famous brand, of which the automated solutions standard reaches the world level. The PLC can provide users various solutions from control to final connection to load. Different with MICOM, the PLC needn’t MCP. With single unit or multiple units communication realized by bus wire and center control system, the PLC can lower cost, improve control capability and safety level.



Advantages of ATB Blower


(1) Energy-saving, high efficiency

Air bearing turbo centrifugal blower adopts air foil bearings, direct-connection technology, high efficiency impeller and motor. No additional friction will occur, and motor power consumption is automatically adjusted according to the output airflow capacity (adjustable range 20-100%), so the energy-saving effect is remarkable.


(2) Low noise

Adopt air bearing and direct-connection way without mechanical contact. Noise is lower than 80dB- @ 1.5m, so there’s no need to install acoustic enclosure.


(3) No oil, no vibration

Air quality reaches ISO 8573-1 0 grade without vibration, so anti-vibration work is not required.


(4) Convenient maintenance

Without gearbox and oil-lubricated bearing of traditional blowers, high and new technology is introduced for convenient maintenance
