Air-suspended blower

The Air-suspended blower-suction high-speed centrifugal blower is a high-efficiency, energy-saving, and environmentally friendly product. It features a simple mechanical structure, few moving parts, robust control, and easy maintenance. It uses automotive-grade, oil-free, high-reliability dynamic air suspension bearings, which operate without friction and with minimal mechanical loss. Advanced permanent magnet synchronous motor technology is adopted, with a maximum speed of up to 95,000 rpm, and it can reach full speed in just 5 seconds. The motor efficiency is as high as 97%, meeting the dual first-level energy efficiency standard. The blower employs a wide-condition, high-efficiency three-dimensional impeller, overcoming key technology limitations in low-specific-speed design, resulting in high efficiency. The main unit's integrated special design keeps noise under 75 dB(A) and vibration below 12 μm. It features stepless adjustment, allowing the fan to start and stop quickly, with continuous start-stop operations exceeding 200,000 times.

Flow range: 5~500 m³/min

Energy saving and high efficiency

The air suspension centrifugal blower uses air bearings, direct connection technology, high-efficiency impeller, permanent magnet brushless DC motor, no additional friction. The fan automatically adjusts the power consumption of the motor according to the output (air volume adjustable range of 40-100%) to maintain the high efficiency of the equipment operation.
2. No vibration, low noise
Air bearing and direct connection technology are adopted, no vibration is generated, and the fan does not need to be equipped with sound insulation devices; The equipment is lightweight, does not need to set up a special foundation, and the installation layout is simple and flexible.
3. No lubricating oil
The fan adopts air bearing technology, and the system does not require a lubricating oil system, providing clean air to special industries such as electronics, medicine, food, etc. The air bearing service temperature reaches 600 degrees, and all the shortcomings of the oil-based bearing system have been successfully solved.
4. No maintenance
There is no gearbox and oil-based bearings necessary for traditional fans, we use a series of high-tech impellers and motors without couplings, direct connection, intelligent control system, key components use AL7075 (aviation aluminum) These technologies ensure that the equipment is maintenance-free, reduce the user's maintenance costs, and improve the stability of the operation of the gas supply system.
5. Convenient operation control
It can perform self-check and constant pressure operation on the fan speed, pressure, temperature, flow rate, etc. on the personal computer, load/no load operation, overload control, and unmanned operation through anti-surge control. The fan regulates the flow rate by adjusting the number of revolutions of the impeller. The flow rate can be easily adjusted by adjusting the rpm according to the temperature and pressure changes of the intake air. Flow can be adjusted automatically and manually.
6. The installation space of the equipment is small
The air suspension centrifugal blower equipment is light in weight, small in size and easy to install, which can save a lot of investment in the user's building and auxiliary electrical control system.
Key benefits:
High reliability and simple maintenance
Due to the adoption of the two core high-tech technologies of "high-speed direct motor" and "air suspension bearing", the speed increase gear, coupling, lubrication system and cooling fan necessary for traditional single-stage high-speed turbine blowers are abandoned, so as to greatly improve the process performance and operation reliability of the product, avoid noise, vibration and secondary pollution caused by waste lubricating oil to the environment, greatly reduce the equipment maintenance workload, and save equipment maintenance costs.
