◇ spindle - using 45 # steel after treatment by the modulation fine car models from fresh air ventilation to ensure adequate finish and dimensional accuracy, the basic structure consists of a wooden box, a wooden sliding wooden handle and activities. The operator manually pull activity boxes, air infiltration through the inlet port sack; compressed wooden box, inside the air through the vent into the output duct, and finally into the smelting furnace for iron. Implementation of the program are: to rely on mechanical air, the wind plate of fresh air ventilator, forcing the formation of new wind flow field within the system. Which uses the benefits of XQ-6A-type machine outdoor fresh air into the room fresh air ventilator, with the benefits of XQ-6B-type machine or in the benefit XL- series porous convection dryer indoor stale air from the outdoors. The product system is a time to keep indoor air clean and fresh new environmentally friendly appliances. This independent indoor air replacement, clean the circulatory system-wide hot new wind ventilators, the exclusion of indoor air pollution at the same time, enter 100% natural fresh air and fresh air enter the room first by filtration, sterilization, heat, oxygen, etc. number processing, then into the room.
