etc.
Significantly reduces the need for regular cleaning and maintenance
High temperature adaptability
Special thermal management system and material selection
Stable operation in high-temperature environments above 50°C.
Meet the needs of special occasions, such as computer rooms, heat
source systems, etc.
Programmable control system
Built-in advanced PLC controller and human-machine interface.
Users can adjust the parameters according to the actual needs of
programming
Supports networking and docking with building automation system.
Outstanding anti-vibration performance
Magnetic levitation design eliminates mechanical vibration sources
Optimised fan structure to withstand strong vibrations
Suitable for earthquake-prone, severe vibration occasions
Performance Features
Energy saving and high efficiency
High-speed permanent magnet motor and high-efficiency ternary flow
impeller are directly coupled.
More than 30% energy-saving than traditional Roots fan.
More than 20% energy-saving than multi-stage centrifugal blower.
More than 10% energy-saving than single-stage high-speed
centrifugal blower.
Low noise
Adopting self-balancing technology, the vibration amount of
magnetic levitation bearing is one order of magnitude smaller than
that of traditional bearing and no friction. At the same time to
take the active damping design, stable operation, body vibration is
very small, fan noise at 80dB (A) or so.
Maintenance-free
Integrated design, skid mounted structure, easy installation, one
key start and stop. Daily operation, free of mechanical
maintenance, only need to replace the filter.
Intelligent control
Adopting PLC+GPRS/3G/4G, it can monitor the running status of the
fan in real time, and realise the intelligent regulation of wind
volume, wind pressure, rotational speed, etc. as well as manual
mode control. In case of failure, it can also be remotely repaired
and debugged.

When the use conditions of the blower and the above table does not
match, the need for performance conversion, our company can be
non-standard design according to user requirements to meet the
specific needs of users of various working conditions.
core technology
Core Technology with independent intellectual property
right-Magnetic Bearing design and control technology
With independent intellectual property rights of 5 degrees of
freedom magnetic levitation bearing technology, can ensure that
when the equipment is energised, the rotor system can be levitated
by electromagnetic force. The controller ensures more than 10,000
times of signal acquisition per second and gives real-time
correction signals synchronously to ensure the stable levitation of
the high-speed rotor.
With redundant power supply system and protection bearings to
achieve multiple protection, will not cause any damage due to
sudden power failure or fault shutdown.
