Configuration:

Shell Material: Die-cast aluminum, which is stronger than ordinary aluminum alloys and contributes to weight reduction compared to iron shell fans.

2. Motor Performance: Utilizes a wide-range, wide-voltage motor, including: Single-phase 110V/230V, Industrial three-phase: 220/380/415/660V, etc. The motor frequency can be adjusted to 45-60Hz. IP54 protection class, F insulation grade.

3. Blower Oil Seals: Utilizing MERKEL oil seals, their lip edge temperature is 20~50℃ higher than the working medium temperature during operation compared to general oil seals, offering more stable performance and longer lifespan.

4. Fan Bearings: Components are fitted with SKF or NSK brand bearings. Compared to domestic Luoyang or Renben bearings, they offer stable performance and long lifespan, ensuring prolonged operation of the fan.

Usage and Maintenance:

1. The fan should be placed on a level surface, with a clean, dry, and well-ventilated surrounding environment.

2. The fan blade rotation direction must match the arrow direction indicated on the fan housing.

3. When the fan is in operation, avoid completely blocking the intake and exhaust air openings to prevent excessive heat generation in the fan and overcurrent in the motor, which may damage the air pump.

4. The fan, excluding the two bearings of the motor rotor, has no direct contact or friction with other parts.

5. Filter screens at both ends of the intake and exhaust should be cleaned as needed to prevent blockages and ensure proper usage.

6. Bearing Replacement: Replacement of bearings must be performed by someone familiar with the repair work. First, loosen the bolts on the pump cover, then disassemble the components in the order shown. Clean the removed parts and reassemble them in reverse order. Do not force the impeller off during disassembly; pull it out instead. Also, do not forget the adjustment shims to avoid affecting the pre-adjusted gaps at the factory.

7. Strictly prohibited: solids, liquids, and corrosive gases from entering the pump housing.

Broadly used in environmental water treatment aeration, electroplating tank liquid mixing, dust removal and ventilation, photographic plate making machines, cigarette filter tip forming machines, special breeding aeration, paper cutting machines, screen printing machines, injection molding machines, lamp industry, automatic feeding and drying machines, atomized drying liquid powder filling machines, welding equipment, film machinery, vacuum packaging, paper conveying, fluid conveying, dry cleaning, pressing, food processing, gas transmission, feeding and collection, etc.
