1. Above 96.5% smoke collecting rate, above 95% particle eliminating rate, its efficiency of raw material collecting is obvious.
2. The creative method of separation between electric device and mainframe, it makes operation more convenient and can avoid water vapour and oil fume etc. flowing into the electric device.
3. The body case adopting the integrated welding structure, which can avoid leaking oil and running oil.
4. Adopting the function of discharging electricity protection, short circuit protection and arc extinction protection etc., as well as the smart de ng fire checking system, all these can ensure device could be used safely.
5. One-click starting and stopping function, this fool controlling design makes operate easy and convenient to maintain, tracking operating condition in time and fault warning system that make operate humanized.

Using automobile hinges, hasps and hermetic technology of refrigerator, this strengthening the seal performance, so reduction of running air is above 15% higher than traditional devices.
