Frequently Asked Questions

What are the main energy-saving benefits of this blower?
This air suspension blower provides over 30% energy savings compared to traditional Roots blowers due to its high-speed PMSM motor and friction-free air bearings.
Is the air output 100% oil-free?
Yes. Since the system uses air suspension bearings instead of traditional lubricated bearings, no oil is required, ensuring 100% oil-free air delivery.
What kind of maintenance is required?
The system is virtually maintenance-free. There are no belts to tighten or oil to change. The only regular requirement is replacing the air intake filter.
Can the blower handle variable flow requirements?
Yes, it features a smart touch screen controller and high-speed inverter that allows for non-polar variable-speed adjustment to match specific pressure and flow needs.
How loud is the equipment during operation?
The blower operates very quietly, with noise levels typically ≤75dB, thanks to its patented labyrinth integrated silencer design.
Does the installation require a specialized foundation?
No, the equipment is integrated and intelligent. It does not require a buried foundation. You simply need to connect the exhaust pipe and power line.
