What is the difference between the ventilator and the draft fan (G and Y)?

What is the difference between the ventilator and the draft fan (G and Y)?

Answer:

And ventilation, drying and feeding of cereals, wind tunnel and hovercraft inflatable and propulsion.
Modern fans are widely used for ventilation, dust and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and ventilation in boilers and industrial furnaces, air conditioning equipment and cooling in household appliances
The ventilator is a mechanical machine that relies on the input of mechanical energy, which increases the gas pressure and sends the gas together. It is a driven fluid machine.
Its resistance to grain erosion and wear performance at least ordinary tungsten carbide surfacing, spray spray welding and alloy powder welding and other conventional treatment methods to improve more than 5 times higher than the matrix 16Mn steel more than 100 times; thickness of 1.5mm ceramic actually use
As the fan blade working surface composite ceramic layer hardness HRA ≥ 86 (toughened alumina composite material), local wear serious parts of the use of secondary sintered silicon nitride toughened ceramic or zirconia toughened alumina ceramic, up to HRA94 above,
