Product Details
Noise management is a critical requirement for high-performance air handling in occupied workspaces, which is why the Low Noise Double Stage Regenerative Blower integrates advanced acoustic damping with dual-stage pneumatic power. Constructed with an aviation-grade aluminum alloy casing and two precision-balanced impellers, this unit delivers up to 620 mbar of pressure while maintaining a quiet environment. The Low Noise Double Stage Regenerative Blower utilizes a specialized silencer pipe lined with high-density sound-absorbing sponge and silencer mesh, effectively absorbing high-frequency mechanical hum and air turbulence before it exits the machine.
Inside the Low Noise Double Stage Regenerative Blower, a 100% pure copper coil motor and high-precision C&U bearings ensure steady 2800 rpm rotation without the vibration drift of standard fans. The regenerative side-channel principle ensures the output remains 100% oil-free, making it safe for medical vacuum and electronic component drying. Each unit is individually balanced and QC-certified at Yijia's 2,550m2 Taizhou facility to ensure consistent build quality. We support global voltage customization, making this low-noise model the professional choice for international buyers seeking powerful air solutions that respect the workspace acoustic profile.

Application scenarios introduction
Micro-contamination is the enemy of electronics manufacturing. Our oil-free blowers provide a clean pneumatic source for "PCB drying" and dust management. After chemical etching and washing, air knives driven by the blower remove all moisture and micro-dust from the circuit boards, preventing oxidation and preparing them for soldering. For component logistics, the blower powers "fast and accurate delivery of tickets and documents" between clean-room stations. In the maintenance of automated lines, "industrial dust collection" systems extract debris and hair remnants that could interfere with optical sensors. The precision-balanced rotor ensures the operation remains vibration-free, protecting the delicate alignment of pick-and-place machinery.

FAQ
1. Q: Does a 15kW blower provide more vacuum than a 7.5kW model?
A: Generally yes; larger motors support larger impellers that generate deeper vacuum levels.
2. Q: What is the maximum vacuum for the 2XGB series?
A: Our top-tier double-stage models reach down to -450 mbar.
3. Q: How does altitude affect performance?
A: Higher altitudes have thinner air; you may need a larger motor to achieve the same pressure at 2000m+ height.
4. Q: Can I run two blowers in parallel to double the flow?
A: Yes, parallel installation is a common way to increase total m3/h flow for large systems.
5. Q: Can I run two blowers in series to double the pressure?
A: Theoretically yes, but our double-stage series usually satisfies high-pressure needs in a single footprint.
6. Q: Does the noise level increase at 60Hz?
A: Slightly, as the rotational speed increases from 2800 to 3400 rpm.
7. Q: What happens if I use a pipe smaller than the port size?
A: This creates excessive back-pressure, which reduces airflow and causes the motor to run hotter.
8. Q: Is the performance curve (H/Q curve) available?
A: Yes, we provide detailed performance graphs showing the relationship between flow and pressure for every model.
9. Q: How much air volume is lost at maximum pressure?
A: Consult the performance curve; airflow decreases as the system resistance (pressure) increases.
10. Q: Can these blowers handle gases other than air?
A: They are designed for clean air and non-flammable/non-corrosive gases; consult us for specific gas compatibility.
