Primary/medium efficiency filter: clean the surface paint mist floccules after each shift, and replace the filter cotton when the dust thickness exceeds 1 cm or the resistance doubles.
High-efficiency filter cotton: visually check the uniformity of light transmission, and replace it immediately if local dark spots appear (normal life is about 400 hours).
Wet water cyclone/Venturi spray booth: clean the trough to settle paint residue daily and keep the water level at the standard line; check the pH value of circulating water weekly (preferably maintained at 6-8), and add neutralizer when the acidity exceeds the standard.
Dry spray booth: check the saturation of activated carbon fiber board or paper filter box, and replace it when the paint mist adhesion reaches 80 or the air flow resistance increases by 50.
Test the closing gap of the door of the room body, and the rubber sealing strip has no hardening and cracking; the micro-positive pressure value is stable in the range of 15-30 Pa.
Clean the scale at the throat of the Venturi tube every month to prevent uneven water flow distribution from reducing the paint mist capture rate.
Check the corrosion of the booster pump impeller quarterly, and replace it if the thickness is reduced by more than 30.
Adjust the uniformity of the overflow water curtain every week to ensure that there is no interruption area.
Replace VOC adsorption materials every 200 hours to avoid secondary pollution.
Customize the filter material replacement cycle according to the local climate (such as high humidity in coastal areas and dry inland areas), and increase the frequency of dehumidifier maintenance during the rainy season in the south.
Warehouses in the United States, Mexico, and Vietnam always have 15 types of core components such as high-efficiency filter cotton and hydrocyclone blades.
Optional pressure difference/temperature and humidity sensor group, real-time push equipment status to the mobile phone, unplanned downtime reduced by 50
