01CORE TECHNOLOGY

Four core technologies.
They define the machine.

Blower performance is not set by one component. It comes from the coordination of bearing, motor, impeller and system control.

Air foil bearing, foil strip and bearing housing

Air foil bearings

An air film replaces mechanical contact: no oil, no continuous wear. Multiple high-load bearing platforms are developed and produced in-house.

AIR FOIL BEARING

High-speed permanent-magnet motor stator and windings

High-speed PM motors

Up to 95% efficiency and 220°C insulation class. Titanium rotors and embedded samarium-cobalt magnets keep the motor light, strong and heat-tolerant.

HIGH-SPEED PM MOTOR

3D impellers

CFD-led blade and passage design balances pressure ratio, wide operating range, low vibration and low noise.

3D AERODYNAMIC IMPELLER

System integration

Multi-physics simulation aligns mechanical, aerodynamic, electromagnetic, thermal and vibration behaviour at the complete-machine level.

SYSTEM INTEGRATION

Air film Rotation Foil

AIR FOIL BEARING

Air-film lubrication.
Quieter. Cleaner.

As the rotor accelerates, air is drawn into the micron-scale gap between the foil and the shaft. The resulting aerodynamic film carries the rotor. Under normal operation there is no direct metal-to-metal contact, so no oil is required and there is no continuous mechanical bearing wear.

01Oil-free: no oil mist in the air stream, suitable for cleanrooms and high-purity processes.
02Non-contact: no mechanical bearing, significantly lower vibration and noise.
03Bearing maintenance-free: no grease, no oil circuit or oil filter to service.

02CORE ADVANTAGES / WHY AIR FOIL

Five advantages.
A model for energy upgrades.

Why air foil? Because it solves footprint, heat, noise, cleanliness and energy in the same architecture.

LANFENG air foil and conventional blower comparison — LFTP / compared with a conventional unit

01 / FOOTPRINT

Smaller footprint

1/3installation space

About one third of the installation space at the same duty point — less framing, less pipework and easier integration.

Less spaceLess framingEasy fit

02 / THERMAL

Thermal management

36–42°C

Air-film lubrication cuts friction heat, while the motor and bearings are managed as separate thermal zones.

03 / LOW NOISE

Low noise

73.3dB(A)

The rotor rides on an air film instead of mechanical bearings, reducing friction and high-frequency vibration.

LANFENG high-speed air foil blower — LFTP / 5.5 kW prototype

05 / ENERGY · WHY AIR FOIL

Energy savings

63.4% less power

A 5.5 kW air foil unit replaced two 7.5 kW scroll blowers at comparable holding performance, cutting measured power by 63.4%.

Conventional 2 × 7.5 kW15.0 kW

LFTP 5.5 kW5.0 kW

Test data comes from specific prototypes and conditions. Actual values vary with model, speed, pipework and installation.

03PRODUCT MATRIX

Five series.
2–80 kPa coverage.

Five series, 27 models, 1.5–22 kW and 2–80 kPa. Every model starts from a real operating condition, not from a catalogue guess.

LFTP / AXIAL FLOW LANFENG axial flow air foil blower

AXIAL FLOW

Low pressure, high flow — built for drying and aeration

Air moves along the axis to deliver high volume at low pressure. Ideal for PCB and ultrasonic cleaning air-knife drying, large-area aeration and water circulation.

Power range2.2–22 kW

Pressure range8–10 kPa

Flow range553–6,160 m³/h

04APPLICATIONS

Six processes.
One air-source logic.

From the water film on a PCB to the dissolved oxygen in a pond; from lint in a textile mill to the holding force on a cutting table — every process needs a different combination of pressure, flow and control.
