Fresh air is sucked air conditioning, filtering through the early effect, and after the final filtration efficiency ceiling cotton filters, clean air is sent to paint room, and air containing dust is retained on the filter bags and filter cotton, long time without replacement will not only affect the paint room into the hot air flow and speed, but also will enter the room temperature paint contains excessive dust in the wind, and therefore must be replaced periodically cotton filters. 1, the use of cotton filters, must ensure the integrity of the seal between the filter cotton and the support frame. Gaskets should check their elasticity, should be replaced if the elasticity is not good. The old filter cotton disassembled, be sure to gently, to prevent dust into the atmosphere. Then cleaned support frame, and then install the new filter cotton up. Scattered in the dust of the earth should be promptly dust with a vacuum cleaner. 2, high temperature paint room filter cotton panels should be fixed and sealed, cotton filters should be installed to ensure that the airflow into the windward side by cotton filters, flow from the outlet side (leeward side). Cotton filter media used in a fixed hierarchy has its density, and therefore more clean side of the filter on to the leeward side. High temperature paint room filter cotton should be replaced, otherwise it will not only affect the air flow system, will reduce the use of cotton filter effects and life. (3) should always check whether the surrounding media are well sealed to the frame, any reason not completely sealed or other reasons without roof leaks caused by cotton filter air filter, will be outside, inside the duct, equipment on the dust particles, debris, slag powder into the paint room temperature, so that the spray effect of the product is greatly affected. In the case of moderate yield, high-temperature paint room filter cotton replaced every three months as normal, but still determined according to local air quality. Filtered cotton paint room temperature using each divided into three stages, namely pre-filter, filter and roof paint splashing filter. Article Source: www.jstzyd.com
