Frequently Asked Questions about FB90B
The FB90B is our most powerful heavy-duty model, featuring a 2550W (3.5HP) motor. It is engineered to support 6 to 9 dental chairs simultaneously with a massive airflow of 315 L/min, making it the perfect choice for large dental centers and hospital departments.
The FB90B utilizes a triple-motor system. This design provides redundancy: if one motor requires maintenance, the other two continue to supply air, ensuring your clinic never experiences downtime. It also allows for more efficient power management during lower-demand periods.
The 90L large-capacity tank acts as a massive pressure buffer. It reduces the frequency of the motors starting and stopping, which significantly extends the lifespan of the compressor and ensures a consistent, high-volume air supply even during peak hours.
Every FB90B unit is equipped with an integrated high-flow air dryer and multi-stage filtration. This system removes 99.9% of moisture and particulates down to 0.01 micron, providing medical-grade, oil-free dry air that exceeds international safety standards for dental surgery.
While the FB90B is designed with efficient heat dissipation and low-vibration rubber feet, we recommend placing it in a well-ventilated equipment room. Despite its 3.5HP power, it maintains a relatively quiet operation at ≤65 dB(A), which is impressively low for its performance class.
