   I. Exhaust extraction drum: The drum consists of fixture, rotating mechanism, high temperature
resistance inhaling hose and high temperature resistance rubber nozzle.

II. Air conduct and fan: The air conduct adopts 0.8 galvanized plate for compression molding, and is
endurable for 10 years with high structure strength and convenient installation; the fan adopts the latest NC
processing rotor, with high wind pressure, low noise and high wind volume.

III. Electric mechanism: adopts aluminum alloy low-noise motor and 36 times reduction gear, which is
stable at the top and bottom, and it takes only 20 seconds from the highest point to the operation terminal.

III. Electric mechanism: adopts aluminum alloy low-noise motor and 36 times reduction gear, which is

IV. Intelligent NC system: This system adopts computer for
centralized control of fully digitalized data collection control, where
the max. communication distance is 1,000m, and its best feature is
being able to control from 0~24 parking lot terminals and extend, to
perform direct point-to-point control of every terminal.
