Product Details
Achieving high performance in industrial air systems requires the precision of a Double Stage Regenerative Blower High Pressure manufactured by Taizhou Yijia Electromechanical Co., Ltd. Unlike standard single-impeller models, this dual-stage machine utilizes two series-mounted impellers on a single shaft to multiply internal air acceleration, reaching discharge pressures up to 620 mbar and vacuum levels down to -450 mbar. The entire pump casing and impeller set are precision-cast from high-silicon aluminum alloy, offering a spark-free, corrosion-resistant housing that excels in the thermal management of high-pressure air handle tasks. The exterior is treated with a professional phosphated process and electrostatic spray painting, ensuring long-term durability in humid or chemically active environments.
Inside the Double Stage Regenerative Blower High Pressure, every component is selected for maximum reliability during 24/7 industrial shifts. The unit is powered by a high-torque 100% pure copper coil motor, which provides 20% higher conductivity and better resistive heat loss than aluminum alternatives, ensuring stable torque at 2800 rpm. This is paired with world-class C&U bearings featuring full-seal rubber rings, rated for 180°C heat resistance to prevent mechanical friction failure. The 20-part precision assembly includes a built-in silencer pipe lined with high-density sound-absorbing sponge, holding the noise floor between 55dB and 84dB. Both air ports feature a dual-port layout with a flange interface, allowing for secure and leak-proof integration into various industrial ducting networks for aeration, drying, and conveying.
Choosing a Double Stage Regenerative Blower High Pressure ensures a powerful and reliable pneumatic partner for your global factory operations, backed by Yijia's 2,550m2 manufacturing facility and daily output of 8,000 units. Each blower undergoes a multi-point QC audit, including dynamic balancing and pressure testing, before receiving its individual certificate of conformity. We support extensive OEM customization, including voltage adaptation for 220V/380V/480V grids and frequency selection for 50Hz or 60Hz. With a proven track record in over 60 countries, this high-pressure blower represents the definitive choice for industries requiring clean, oil-free, and powerful air solutions for the most demanding applications.

Introduction to use cases
In the precision-driven world of offset and steel plate printing, the regenerative blower is a multi-functional workhorse. Its vacuum side provides the critical "suction pressure" required to fix paper or film onto photographic plates, ensuring registration is perfect during high-speed runs. On the output side, it drives air-knife systems for "printing forced drying," where a high-velocity stream of oil-free air sets ink instantly, preventing smudge defects. The blower also supports logistics within the print shop, powering pneumatic tubes for the "fast delivery of documents" and job tickets between workstations. By replacing complex mechanical clamps with non-contact vacuum holding, it protects sensitive paper surfaces while maintaining industrial duty cycles.

FAQ
1. Q: What is the main difference between single-stage and double-stage blowers?
A: Double-stage blowers use two impellers in series to achieve nearly double the pressure of single-stage units of equivalent power.
2. Q: Can a double-stage blower achieve 600mbar?
A: Yes, our larger double-stage models are specifically designed to reach pressures up to 620 mbar for deep-tank applications.
3. Q: Is the energy efficiency higher in double-stage models?
A: Yes, they provide higher pressure-to-power ratios, making them more efficient for tasks requiring significant pneumatic force.
4. Q: Are double-stage blowers much louder than single-stage?
A: While more powerful, our built-in silencers keep the noise level between 55-84 dB, which is highly competitive.
5. Q: Does the double-stage design increase the physical size significantly?
A: They are slightly longer due to the dual-impeller housing, but remain compact enough for most machine integrations.
6. Q: Can I use a double-stage blower for vacuum instead of blowing?
A: Absolutely. They excel at high-vacuum tasks, reaching levels down to -450 mbar.
7. Q: Are there more wear-parts in a double-stage unit?
A: No, the non-contact side-channel principle remains the same; only the number of impellers increases.
8. Q: Is a double-stage blower suitable for 24/7 duty?
A: Yes, our pure copper motors are engineered for continuous industrial duty cycles.
9. Q: Why should I choose double-stage for pond aeration?
A: It provides the high pressure needed to overcome deep water hydrostatic head in ponds over 2-3 meters deep.
10. Q: Do double-stage units require more frequent maintenance?
A: No, maintenance requirements are the same as single-stage units-primarily filter cleaning and periodic inspection.
