APPLICATIONS

Six processes.
One air logic.

Drying, aeration, vacuum holding, high-temperature circulation and industrial air supply all demand different pressure, flow and cleanliness. Here is how LANFENG approaches six typical applications.

PCB electronics 01 / PCB & ULTRASONIC DRYING Oil-free clean air · air-knife drying
PCB / ultrasonic cleaning

PCB drying:
high volume, low energy.

PCBs, semiconductors and ultrasonically cleaned parts need fast, consistent drying. Scroll blowers lose efficiency at low pressure and can introduce oil-mist risk. LANFENG uses oil-free air foil bearings and axial or mixed-flow impellers to deliver clean, controllable air-knife supply.

Industry challenge

Clean, oil-free air; high volume at low pressure; noise and temperature control in the workshop.

LANFENG solution

Axial flow for low-pressure volume, mixed flow for higher air-knife resistance; VFD matches board width and line speed.

Aquaculture pond aerators 02 / AQUACULTURE AERATION Deep-water aeration · high-density farming
Aquaculture

Aquaculture aeration:
stable oxygen, lower energy.

Aeration is often the largest electricity cost on a fish farm. Water depth sets static head, pipework sets resistance and stocking density sets oxygen demand. LANFENG mixed-flow and centrifugal series provide stable air volume from 15 to 80 kPa, with variable speed and optional remote monitoring.

Industry challenge

Deep water, long pipe runs, high energy cost and the risk of oil contamination.

LANFENG solution

Axial for shallow, wide ponds; mixed flow or centrifugal for deep water and long pipes; oil-free compression with optional 4G/APP monitoring.

Textile production line 03 / TEXTILE Wide pressure · anti-wrapping · efficient
Textile lint removal / dyeing

Textile lint removal:
wide pressure, anti-wrapping.

Textile lint removal, dyeing and finishing demand a wide pressure range. Conventional centrifugal blowers have a narrow efficient window and impellers can wrap with lint. LANFENG mixed-flow models cover 5–40 kPa, with an optimised impeller design that reduces wrapping risk and the number of machine variants.

Industry challenge

Different pressures across machines; lint wrapping; high continuous energy use and downtime.

LANFENG solution

Mixed-flow range from 5 to 40 kPa; anti-wrapping impeller; VFD matched to machine speed.

CNC cutting machine 04 / VACUUM HOLDING Closed-loop · stable holding
Vacuum holding / oscillating-knife cutting

Vacuum holding:
constant pressure, on demand.

Oscillating-knife cutting, dust collection, drilling and automated vacuum handling need stable vacuum, not constant maximum power. The LANFENG F series uses closed-loop constant-vacuum control, adjusting speed to sheet opening, material and pipe condition — avoiding over-holding energy and under-holding slip.

Industry challenge

Holding force varies with sheet opening; fixed-speed blowers run at full power; oil can contaminate workpieces.

LANFENG solution

F-series vacuum impeller with constant-vacuum closed loop; −18 to −28 kPa; oil-free, low noise, bearing maintenance-free.

High-temperature industrial furnace 05 / HIGH-TEMPERATURE DRYING 60–100°C · no grease
High-temperature drying / heat circulation

High-temperature drying:
oil-free, heat-resistant, continuous.

At high temperature, grease evaporates and ages, risking both product contamination and bearing failure. The LANFENG G series replaces grease with air lubrication and optimises motor and bearing thermal management for 60–100°C inlet air, suitable for wafer drying, coating curing and high-temperature loops.

Industry challenge

Grease failure at high temperature; cleanroom cleanliness; high energy use and failure rates.

LANFENG solution

G-series high-temperature models; oil-free air lubrication; intelligent temperature monitoring; cleanroom-compatible.

Metal surface treatment 06 / SURFACE TREATMENT Demanding environments · continuous operation
Surface treatment / industrial air

Surface treatment:
corrosion-resistant, continuous duty.

Plating, cleaning, coating and general industrial air often involve humidity, acid or alkaline gases and long continuous operation. LANFENG can specify surface protection and monitoring options for the environment, while the oil-free, low-vibration air foil structure reduces long-term maintenance pressure.

Industry challenge

Humidity and corrosive gases; long run hours; frequent maintenance and expensive downtime.

LANFENG solution

Axial or mixed-flow models matched to flow and pressure; optional corrosion protection and remote monitoring; fewer maintenance points.
