Frequently Asked Questions

• What is the working pressure range of the LBV series low-pressure air compressor?
  The LBV series supports an exhaust pressure range of 3.0–4.5 bar, with the operating pressure freely adjustable between 0.3–0.45 MPa to meet various low-pressure application requirements.
• What FAD (Free Air Delivery) range does the LBV series cover?
  The LBV series covers a broad FAD range of 33.5–65 m³/min, with models available at 132 kW, 160 kW, 185 kW, and 200 kW driving power to suit different production scales.
• How does the LBV series ensure reliable operation in high-temperature environments?
  The LBV series uses a time-proven twin-screw air-end combined with a backward-curved centrifugal fan that delivers high cooling air pressure and more than 30% cooling margin, ensuring stable performance even in high-ambient-temperature conditions.
• What technology is used in the oil separation system?
  The oil separation system is developed using advanced CFD (Computational Fluid Dynamics) fluid simulation with an RNG k-ε turbulence model. Simulated results are validated against measured data to ensure highly efficient and reliable oil separation with no oil leakage.
• Does the LBV series support remote monitoring and intelligent control?
  Yes. Each LBV unit is equipped with the "Deman Cloud Control" intelligent remote control system, which enables 24/7 digital monitoring via multiple sensors and warning functions, ensuring continuous and efficient operation.
• How often should the external air intake filter be replaced, and what are its maintenance requirements?
  The external air intake filter is designed to filter dust and fluff and is washable for reuse. It should be replaced every 3,000 operating hours. All filters are uniform in size, making replacement quick and straightforward.
