Energy saving 30% 75KW 40-120Kpa Magnetic levitation blower

It is a high-speed centrifugal blower whose rotor is suspended and driven by active magnetic bearings and a permanent magnet motor, with no mechanical contact in the rotating system. Air enters axially and is accelerated by the high-speed impeller to deliver large volumes of low-pressure air efficiently and quietly, with output precisely regulated by a variable speed drive.

Roots blowers are positive-displacement machines with fixed output and poor efficiency at partial load, plus oil-lubricated gears and bearings that require regular maintenance. Magnetic levitation centrifugal blowers run contact-free, regulate output smoothly from 45% to 100%, and typically consume 30–50% less energy — the largest single cost saving in aeration applications.

The rotor levitates and rotates without touching the stator, so there is zero mechanical wear, no lubricating oil, no gears and no bearing replacement for the machine's life. Bearings are actively controlled, enabling extremely high rotational speed with very low vibration and long, reliable service life.

Our magnetic levitation centrifugal blowers typically deliver discharge pressures from 30 to 120 kPa (0.3–1.2 bar) with flows ranging from about 20 to 300 m³/min, covering most aeration and pneumatic conveying duties. Send us your required flow, pressure and site conditions and we will match the optimum model.

It is ideal for continuous, large-volume low-pressure air: municipal and industrial wastewater aeration, aquaculture oxygenation, pneumatic conveying, desulfurization (flue gas), cement and chemical plants, food fermentation, textile and mining. Anywhere aeration or air blowing runs many hours a day, it delivers the lowest total cost of ownership.

Compared with a conventional Roots blower, typical energy savings are 30–50%, driven by high-efficiency motors, the aero efficiency of the impeller and precise variable speed regulation that matches air flow to real demand. For aeration plants running 24/7, the annual electricity saving often reaches tens of thousands of dollars and pays back the equipment difference within 1–3 years.

Very quiet for its capacity — typically 70–85 dB(A) at 1 m with the standard acoustic enclosure, and much lower than Roots blowers. Low vibration means no special soundproofing room or heavy foundation is required; it can be installed indoors or outdoors.

Almost none. There is no oil, no gearbox and no mechanical bearing wear. Routine work is limited to replacing the intake air filter, cleaning the cooler and periodic system checks. This cuts consumables, labor and downtime dramatically over the machine's lifetime.

Each unit has a PLC + touchscreen controller offering auto start/stop, pressure or flow control, multi-unit load balancing, fault self-diagnosis and data logging. Optional cloud remote monitoring lets operators or our engineers view real-time status, energy use and alarms from anywhere, enabling predictive maintenance.

The variable speed drive provides smooth regulation from 45% to 100% of rated flow without surge or wasteful blow-off. In multi-unit stations, the controller automatically sequences machines so the whole system always runs at its best efficiency point.

Installation is simple: a level platform or concrete pad with adequate clearance, a power connection and an air outlet duct. Because vibration is minimal, expensive anti-vibration foundations are not needed. We supply installation drawings, manuals and remote commissioning support.

Yes. Outdoor and high-protection (IP54/IP55) versions are available, with an operating ambient range of roughly −10°C to 45°C and optional cooling packages for tropical, dusty or corrosive sites. We confirm site conditions and configure the right protection grade.

Yes. Our control system supports multi-unit stations with automatic load sharing, rotation and failure takeover, so aeration keeps running even if one unit needs service. Integration with existing SCADA/PLC systems and cloud platforms is available.

Thanks to energy savings and near-zero maintenance, payback is typically 1–3 years depending on operating hours, electricity price and the technology being replaced. We provide a free site-specific energy audit and payback calculation before you decide.

Yes. As the manufacturer, we customize voltage/frequency (e.g. 380V/660V/10kV, 50/60Hz), control and communication protocols, cooling options, skid-mounted packages and enclosure types, plus OEM/ODM branding. We also engineer complete aeration systems with piping and diffusers.

Our factory is ISO 9001 certified, and the blowers carry CE certification with additional certificates available for your market. We offer a 12–24 month warranty, 24/7 remote diagnostics and support, installation and commissioning guidance, operator training, and long-term spare parts supply (typically dispatched within 3–7 days).
