Why centrifugal air suspension blower is suitable for stable and constantly running working conditions?
If we want to know the answer of this question,we need to know about the working principle of the air bearing blower:
1.the main parts of the air foil bearing blower is including:high speed permanent magnet synchronous motor,rotating shaft,air foil bearing,thrust bearing,ternary flow impeller,cooling impeller,VFD,PLC control system and other component.air blower knife
2.When the centrifugal air bearing blower connects with the power,the motor will run from low speed to high speed.Since the motor is connecting with the rotating shaft,and shafting connects with the air foil bearing, air foil bearing connects with the ternary flow impeller.The VFD is used for controling the motor running speed.When the motor is running is the speed lower than 8000rpm,the shaft and air foil bearing is touching with each other(If there is connection, there will be friction).The design of the bearing life is start-stop 20,000times.After the motor running speed is more than 8000rpm,the air force surrounding the air foil bearing will counteract the bearing gravity,then the bearing will float and running surrounding the shaft.air vent blower
3.When the bearing of the air blower is running,it will bring the ternary flow impeller to run(since bearing is connecting with the impeller).After the ternary flow impeller runs,it will generate a vacuum area and suck the surrounding air into the ternary flow impeller,then the air will generate the dynamic pressure under the impeller compression,then the compressed air will be dischaged into the user pipeline.
4.When the shaft is rotating,it will bring the motor cooling impeller to run,the running impeller will form an vacuum area and suck the motor surrounding air inside.The air will go through the motor,bring the hot motor air to the vacuum area,then the hot air will be discharged outside the enclosure of the air blowers.
From the above working principle of air bearing blower,we can know that when we start-stop the blower,the air foil bearing has friction with the rotating shaft,when there is friction,there will be abrasion.Therefore,the air suspension blowers is not suitable for frequently start-stop working conditions.

1.What are the maintenance requirements for an air blower knife?
Different types of air blowers have different maintenance requirements,for traditional roots blower,end users need to add oil for lubrication,replace the ball bearing and change the air inlet filter periodically.But for turbo blower,the maintenance is quite easy and convenient,end users only need to change the air inlet filters 1-3 months.
2.About air blower knife customization services
RAETTS has more than 20 peoples R&D team,which can help customer to do customization for the air blowers to meet the different applications
3.About air blower knife warranty
RAETTS warranty time for air bearing blower and maglev turbo blower is 24months,for high speed centrifugal blower is 12 months.
4.About the development history of air blower knife factory
RAETTS was set up in the year of 2011,the first product is super series high speed centrifugal blower(belt-drive type).The second product is developed in 2014,it is the direct-drive type high speed centrifugal blower,higher efficiency than belt-drive type.Both of this two blowers are used as the air source of the air knife drying systems.The air bearing blower was developed in 2018 and maglev turbo blower was developed in 2019.In 2020,we developed turbo compressor,which is to meet different applications which need higher pressure.
5.About air blower knife payment method
RAETTS accept payment by T/T(30% advance payment,70% before shipment)
6.About air blower knife R&D capabilities
RAETTS R&D team has more than 20 people,the chief team leader worked for BYD before,and the technique of whole team is supported by Xi’an Jiaotong University.
7.About air blower knife overseas warehouse
RAETTS is cooperating with global distributors,some distributors has stock or sample in their warehouse.For now,RAETTS has Germany factory warehouse,and we are building the USA warehouse.
8.How does an air blower knife work?
The main structure of the air blower is including motor,shaft,bearing and impeller.When the motor is running,it will drive the shaft to run,then shaft drive bearing to run,then bearing drive the impeller to run.After the impeller runs,it will generate a vacuum area surrounding the impeller and suck the surrounding air inside.Then the air will be compressed by the impeller and discharged outside.
9.About air blower knife raw material procurement system
RAETTS uses ERP management system to manage the suppliers and follow the raw materials production state.
10.About air blower knife technology
RAETTS air bearing blower technology is originated from South Korea and maglev turbo blower technology is originated from Germany.RAETTS also have R&D team from Xi’an Jiaotong University.
11.About air blower knife production skills training
RAETTS will train the production staffs for 3 months before they do production,including:machine operation,assembly,testing and so on.
12.What are the advantages of using an turbo air blower knife?
Comparing with tradition roots blowers,single-stage blowers and multi-stage blowers,turbo blowers effciency is 20%-30% higher,which means using an turbo air blower can help customer to save about 20-30% energy,and then reduce the eletric cost.
13.About air blower knife production capacity
RAETTS production quantity for air bearing blower and maglev turbo blower is about 200pcs/month,for high speed centrifugal blower is about 700pcs/month.
