Air Supply System

Air supply system for the spray paint room operating area by the temperature, humidity, filter clean fresh air equipment. The amount of air flow depends on the size of the wind in the painting room. The size, temperature, humidity and dust removal of the painting room depend on the type of paint sprayed, the appearance quality of the coating and the working environment of the operator. Paint room Typical air conditioning air supply system: bird fence (air inlet) → suction adjustment blinds → pre (early) filter → preheater → washing section and retaining plate → after heater → fan → after filter → Muffler → air conditioning shutters. According to the different needs of users, air conditioning system can have more than the composition of different segments. They are installed in a channel-type body made of galvanized steel. Because the air volume is bigger, only has the heating heating function, because the summer reduces the temperature to consume the energy and the investment is big, generally does not have the cooling device, does not have the cooling function. Heating heat source for hot water, steam, electricity, fuel oil, thermal oil, natural gas. In the northern winter, the outdoor temperature dropped to -20 ℃ the following occasions, can be installed in the suction nozzle of natural gas combustion, direct heating, sandstorms in the large area of the inlet can be added sand filter. In the south, the green environment is good, less sand and high humidity occasions, in order to save investment, can be saved washed section. Water section of the sink, wall panels made of stainless steel, the supply of water quality is better. In the filter before and after the general installation of a pressure gauge, when the pressure reaches a certain value should be replaced when the filter element. The filter element is made of a non-woven filter material. Generally from the plant outside the suction, suction outlet in the strong wind when the sand and dusty places, away from the paint room exhaust outlet a little farther or in the wind at the side, the suction outlet should be installed metal mesh or fence to prevent inhalation of birds . In order to prevent the fan noise into the paint room, in the fan after the air duct should be muffler.

Fan size According to the size of the spray booth and the number of ventilation to determine the number of hours of air supply unit for the spray booth hours per hour and the volume of indoor ventilation product. Temperature, humidity and degree of dust removal depends on the spray paint varieties, coating quality requirements and appearance of the operator's operating environment.
