Delta Electronics High-Pressure Blower Fans are designed for high-impedance and high-suction systems. These centrifugal blowers are ideal for cordless and robot vacuums as well as Continuous Positive Airway Pressure (CPAP) machines for sleep apnea. These fans feature a high air pressure blower design that greatly increases maximum air pressure and fan speed while minimizing fan size. This performance increase is managed by a pulse-width-modulated (PWM) system that can precisely regulate fan speed and pressure for reliable and steady performance. Delta Electronics High-Pressure Blower Fans assist vacuum systems in maintaining proper suction across changing landscapes while also offering continuous pressure flow for assistive devices such as CPAP machines. These fans offer low power consumption and vibration.
