Product Details
Industrial facilities operating on standard three-phase power require the technical integrity of the Double Impeller Ring Blower 380V 50Hz. This series-impeller machine is engineered to generate high-pressure pneumatic force for deep-tank applications, reaching discharge levels up to 620 mbar. By utilizing the Double Impeller Ring Blower 380V 50Hz, operators can drive complex aeration networks or extract hazardous fumes with absolute reliability. The entire casing is cast from precision-machined aluminum alloy, providing a durable, spark-free housing and exceptional heat dissipation capabilities during 24/7 industrial duty cycles.
The performance of the Double Impeller Ring Blower 380V 50Hz is anchored by its 100% pure copper coil motor. By using high-purity cathode copper, we ensure the motor remains 20% more efficient and thermally stable at its rated 2800 rpm speed. Rotation is managed by world-class C&U bearings with full-seal rubber rings, rated for high temperatures up to 180°C. To protect the internal air path, both ports are fitted with dustproof filter mesh, while an integrated silencer duct with built-in sound-absorbing sponge holds noise to professional standards. Every unit is individually QC-certified and receives a certificate of conformity from our Taizhou factory, making it the definitive choice for 380V industrial pneumatic power.

Application scenarios introduction
High-speed dairy packaging depends on consistent vacuum force for carton integrity. Our oil-free vortex blowers provide "milk box vacuum" suction, ensuring that every cartridge is perfectly shaped and held in position for filling. This precision ensures that printed cartons remain fixed during "steel plate printing" of expiration dates and barcodes, preventing Smudged or misaligned markings. Post-filling, the blower's "blowing" function is used in "bottle drying" air knives to clear moisture from the exterior before labeling. Because the air output is 100% oil-free, it provides a hygienic pneumatic source that meets global food packaging standards, ensuring your dairy production line remains efficient, clean, and quiet.

FAQ
1. Q: What is the starting current (LRA) of the 11kW motor?
A: Typically 6-8 times the rated current; we recommend a Soft Starter or Star-Delta starter for this size.
2. Q: What is the maximum back-pressure the XGB 520HH series can handle?
A: It is rated for up to 330 mbar continuous discharge pressure.
3. Q: Do you provide the torque-speed curve for the motor?
A: We can provide detailed motor specifications including torque data upon request for engineering projects.
4. Q: How does the power factor (cos φ) vary with load?
A: Our motors are optimized for a high power factor (typically 0.82-0.88) at full load.
5. Q: Is the impeller keyed to the shaft or press-fitted?
A: It is precision-keyed and secured with a high-strength locking bolt for maximum safety at high RPM.
6. Q: What type of grease is used in the 180°C bearings?
A: We use specialized high-temperature industrial synthetic grease designed for long-life sealed bearings.
7. Q: Can the blower handle air containing 100% relative humidity?
A: Yes, but ensure no liquid water enters the chamber; a water separator may be needed on the intake.
8. Q: What is the leakage rate of the housing under pressure?
A: Our housings are precision-machined and gasketed to ensure near-zero leakage at rated pressures.
9. Q: Are the internal silencer sponges fire-retardant?
A: Yes, we use industrial-grade flame-retardant sound-absorbing materials.
10. Q: Can I get a model with a stainless steel shaft?
A: For highly corrosive applications, we can offer customized units with specialized shaft materials.
