Configuration:

Shell Material: Cast aluminum, which is stronger than ordinary aluminum alloy and contributes to lightweight properties compared to iron shell fans.

2. Motor Performance: Utilizes a wide-frequency, wide-voltage motor, including single-phase 110V/230V and industrial three-phase 220/380/415/660V, with adjustable frequency from 45-60 Hz. IP54 protection class, F insulation class.

3. Blower Oil Seal: Utilizes MERKEL oil seals, which have a lip temperature 20-50℃ higher than the working medium temperature compared to general oil seals, offering greater stability and longer lifespan.

4. Fan Bearings: Components are fitted with SKF or NSK brand bearings. Compared to domestic Luoyang and 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 relatively flat surface, with a clean, dry, and well-ventilated surrounding environment.

2. The fan blade rotation must be in the same direction as the arrow indicated on the fan housing.

3. When the fan is in operation, it is crucial to avoid the intake and exhaust openings being completely blocked to prevent excessive heat generation in the fan and overcurrent in the motor, which could damage the air pump.

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

5. The air intake and exhaust filters should be cleaned as needed to prevent clogging and ensure proper use.

6. Bearing Replacement: Replacement of bearings must be performed by someone familiar with the repair process. First, loosen the bolts on the pump cover, then disassemble the components in the order shown. The removed parts should be cleaned and reassembled in reverse order. Do not force the impeller off; pull it out using a rope. Ensure not to miss the adjustment shims to avoid affecting the pre-set gaps at the factory.

7. Absolutely prohibited: solids, liquids, and corrosive gases are not allowed to enter the pump body.

Widely used in environmental protection water treatment aeration, electroplating tank liquid stirring, 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 transportation, dry cleaning of garments, ironing, food processing, gas conveyance, feeding and collection systems.
