What are the application scenarios of magnetic levitation blower?

With four core advantages of high efficiency, energy saving, low noise, maintenance-free and wide adjustment ratio, magnetic levitation blowers are mainly concentrated in the fields of sewage aeration, industrial desulfurization, chemical transportation, food and pharmaceutical, electronic semiconductors, pneumatic transportation, etc., which are described in detail according to the scenarios below:

First, sewage treatment (the most mainstream, accounting for 60%+)

Application: aeration in biochemical pool (aerobic pool, anaerobic pool and anoxic pool), membrane pool purging, sludge reflux and mixing.

Core requirements: stable low pressure (40–80 kPa), large flow, wide air volume adjustment (20%–100%), low noise and long-term continuous operation.

Advantage value: 30%-50% energy saving compared with traditional roots blower/multistage centrifugal blower; Noise ≤75dB (A), without soundproof room; Magnetic bearing has no friction and maintenance, and its service life is 15 years.

Typical cases: municipal sewage plants, sewage stations in industrial parks, and high-concentration organic wastewater treatment (papermaking/printing and dyeing/food wastewater).

Second, the power/steel/cement industry (desulfurization and denitrification+dust removal)

Application link:

Desulfurization in power plant: conveying oxidized air in limestone-gypsum desulfurization system (pressure 60–120kpa).

Iron and steel sintering machine/pellet: flue gas desulfurization and oxidation, dust removal and pneumatic conveying.

Cement kiln: kiln tail desulfurization and oxidation, raw meal/cement powder transportation.

Core requirements: medium and high pressure (80–150 kPa), continuous stability, anti-surge and dust resistance.

Advantage value: high efficiency under high pressure; Wide speed regulation range, matching load fluctuation; Oil-free lubrication to avoid oil mist pollution of desulfurization slurry.

III. Chemical Industry (Gas Transmission+Reaction Gas Supply)

Application link:

Chemical reaction kettle: air/nitrogen/oxygen pressurized transportation (pressure 50-200kPa), oxidation reaction aeration.

Waste gas treatment: VOCs biological filter aeration, acid-base waste gas neutralization tower blowing.

Powder conveying: closed pneumatic conveying of chemical raw materials/catalysts (leak-proof and explosion-proof).

Core requirements: oil-free, dust-free, explosion-proof, corrosion-resistant and pressure-stable.

Advantage value: magnetic levitation is oil-free, eliminating product pollution; Good sealing performance, suitable for toxic/flammable and explosive gases; Frequency conversion and accurate pressure control ensure stable response.

Four, food/pharmaceutical/beverage industry (sterile air supply+aeration)

Application link:

Fermentation tank aeration: aerobic fermentation of antibiotics, vitamins, beer and soy sauce provides oxygen (pressure 40-80kPa).

Aseptic packaging: positive pressure air supply and aseptic air purging in clean workshop.

Water treatment: biochemical aeration of food processing wastewater, reverse osmosis pre-blast of pure water preparation.

Core requirements: absolutely oil-free, aseptic, low noise and clean.

Advantage value: oil-free bearing+high efficiency filtration, oil-free and aseptic output air, in line with GMP standards; Low noise, improve the workshop environment.

V. Electronic/Semiconductor/Photovoltaic Industry (Clean and Dry Air Supply)

Application link:

Semiconductor wafer factory: fresh air ventilation in clean room, positive pressure maintenance, wafer cleaning, drying and purging.

Photovoltaic cell factory: silicon wafer cleaning, diffusion process and dry air transportation.

Lithium battery factory: electrode coating and drying, dehumidification and air supply in chemical workshop.

Core requirements: ultra-clean, low dew point, oil-free and dust-free, stable pressure.

Advantage value: oil-free output+precision filtration, air cleanliness can reach ISO 1 level; Low vibration (magnetic bearing) to avoid resonance of precision equipment.

Six, paper/printing and dyeing/textile industry (wastewater treatment+pneumatic conveying)

Application link:

Papermaking wastewater: aeration in biochemical pool, black liquor treatment and oxidation.

Printing and dyeing wastewater: aerobic treatment, decolorization and aeration of high chroma/high COD wastewater.

Textile powder: pneumatic conveying of dyes/auxiliaries, dust removal and blast in the workshop.

Core requirements: large flow, moisture resistance, anti-clogging, energy saving.

Advantage value: wide regulation ratio, adapting to water quality fluctuation; Anti-moisture design, suitable for high humidity environment; Save energy and reduce consumption, and reduce the cost of sewage treatment.

VII. Other Special Scenes

Aquaculture: High-density industrial aquaculture ponds are aerated with oxygen (pressure 30–60 kPa), such as prawn and salmon farming.

Landfill leachate treatment: biochemical aeration of high-concentration refractory wastewater+membrane treatment and purging.

Mine ventilation: local ventilation and gas dilution (low pressure and large flow) in small mines.

HVAC: Fresh air transportation and positive pressure ventilation (low noise and energy saving) in large commercial buildings/data centers.

Magnetic levitation value of core pain point in typical pressure and flow range of industry

Municipal sewage 40–80 kPa 5–200 m/min has high energy consumption, high noise, 40% energy saving and maintenance-free.

Power plant desulfurization 60–120 kPa 20–300 m/min, high pressure and low efficiency, load fluctuation, high pressure and high efficiency, wide regulation.

Food fermentation at 40–80 kPa 10–100 m/min has the risk of oil pollution, cleanliness, oil-free sterility and GMP compliance.

Electronic Cleanliness 30–50kpa 5–50m/min Cleanliness, ultra-clean vibration and low vibration.

Summary: The core application of magnetic levitation blower is to replace the traditional high energy consumption blower, which has the most obvious advantages in the scenes of low pressure and large flow, stable transportation of medium and high pressure, clean and oil-free, and long-term continuous operation.
