Product Details
The Two Stage Ring Blower Industrial is engineered to provide the high-pressure pneumatic force required for demanding production lines. Constructed with a precision-cast aluminum alloy housing and two series-mounted impellers, this unit achieves discharge pressures up to 620 mbar and vacuum levels down to -450 mbar. The internal architecture consists of a 20-component precision assembly, including high-grade C&U bearings with full-seal rubber rings, rated for 180°C heat resistance during 24/7 industrial shifts.
At the heart of the Two Stage Ring Blower Industrial is a high-torque 100% pure copper coil motor. By using high-purity cathode copper, we achieve 20% higher conductivity and better resistive heat loss than aluminum alternatives, ensuring stable torque at 2800 rpm. The blower utilizes a regenerative side-channel principle that is entirely oil-free, as rotating impellers never make physical contact with the casing. This contaminant-free design is ideal for pharmaceutical clean rooms, food packaging lines, and high-density aquaculture aeration where air purity is paramount.
Typical deployments for the Two Stage Ring Blower Industrial include deep-pond fish farming diffusers, printing press drying tunnels, and textile mill lint collection. The cast aluminum shell dissipates heat rapidly through integrated radial fins, while the built-in silencer duct keeps noise between 55dB and 84dB. Each unit undergoes dynamic balancing and a multi-point QC audit at our 2,550m2 Taizhou facility before receiving its certificate of conformity. We support extensive OEM customization for global voltages (220V/380V/480V) and frequencies (50/60Hz). With a proven record in over 60 countries, Yijia blowers provide the reliable, factory-direct air solutions your industry demands.

Application scenarios introduction
Deep-water fish farming and shrimp tanks require a steady, high-pressure supply of dissolved oxygen. Our vortex fans are designed for this "oxygen supply in water" role, delivering constant, oil-free air to submerged diffuser networks. Unlike standard fans, the double-stage design can overcome the high hydrostatic pressure found in deep ponds, ensuring oxygen reaches the bottom sediment. This is crucial for high-density aquaculture where stagnant water can lead to stock loss. The corrosion-resistant aluminum shell ensures the blower can operate in humid coastal environments, providing a reliable 24/7 lifeline for your aquatic stock without the risk of oil mist contamination.

FAQ
1. Q: Do you use pure copper windings in your motors?
A: Yes, 100% pure copper wire is used to ensure high conductivity, low heat generation, and long insulation life.
2. Q: What voltage options do you offer for the 7.5kW model?
A: We support 345-415V Delta and 600-720V Wye configurations for 50Hz industrial grids.
3. Q: Can the blower run on 60Hz power for the US market?
A: Yes, our motors are dual-frequency (50/60Hz) compatible, and performance typically increases by 15% at 60Hz.
4. Q: Is it possible to get a single-phase 220V double-stage blower?
A: Yes, we offer single-phase versions for models up to 2.2kW, perfect for workshops and small aquaculture.
5. Q: What is the insulation class of the motor?
A: Our motors feature Class F or Class H insulation, rated for high-temperature stability in demanding environments.
6. Q: Can I use a VFD (Variable Frequency Drive) with these blowers?
A: Most of our three-phase motors are VFD-compatible, allowing for precise airflow and pressure control.
7. Q: Does the motor have thermal protection?
A: Most models include standard thermal sensors; we recommend adding external protection in your control cabinet.
8. Q: What is the protection rating (IP) of the motor?
A: Our standard motors are IP55 rated, providing excellent protection against dust and water splashes.
9. Q: Are the motors explosion-proof?
A: We have a dedicated XGB-B series specifically for explosion-proof requirements in hazardous gas/dust zones.
10. Q: How do I wire the 3-phase motor correctly?
A: A detailed wiring diagram is provided inside the junction box lid, supporting both Star and Delta connections.
