  III Main functions and application scenarios

• 0.4KW medium pressure blower relies onLow power, moderate wind pressure, low noiseThe characteristics are mainly used forLight load, low flowThe gas delivery and pressurization scenarios are as follows:

• 1. Industrial small-scale pressurization and air supply

• Pneumatic control of small equipmentProvide a stable gas source for pneumatic components such as micro cylinders and pneumatic grippers, such as small automated assembly machines and electronic component sorting equipment;

• Mold/cavity dryingHigh pressure air drying for small injection molds and precision instrument chambers, replacing traditional hot air drying (to avoid high-temperature damage to workpieces);

• Industrial furnace combustion assistanceProvide secondary air supply for small laboratory electric furnaces and micro gas burners to optimize combustion efficiency.

• 2. Civil and commercial ventilation and air exchange

• Small fresh air systemSuitable for local fresh air boosting in home study rooms and small offices, with air circulation achieved through filter screens;

• Kitchen oil fume auxiliary emissionProvide auxiliary air pressure for small household side range hoods to solve the problem of poor smoke exhaust caused by excessive negative pressure in high-rise residential flues;

• Aquarium aeration and oxygenationCompared to low-pressure air pumps, oxygen delivery in large aquariums (over 1000L) or small aquaculture seedling ponds can achieve oxygen diffusion in deeper water areas.

4. 4. Other special scenarios

5. Small vacuum adsorptionUsed for vacuum suction of lightweight workpieces such as electronic chips and glass lenses, such as small surface mount machines and lens sorting equipment;

6. Agricultural small sprayMicro atomization spraying equipment for orchards and greenhouses, which atomizes the medicine into fine mist through high-pressure air to improve adhesion rate.

7. 3、 Selection precautions

8. If used forcorrosive medium(such as acid-base mist), customized stainless steel impeller and anti-corrosion coating casing are required;

9. Negative pressure conditions require confirmation of the fan's performance真空度To avoid exceeding the rated range and causing impeller stall;

10. For continuous 24-hour operation scenarios, it is recommended to choose models with F-grade insulation and lifelong bearing lubrication.
