The painting fan is an important part of the coating equipment, its role is to provide sufficient air flow to ensure the smooth progress of the painting process. This article will introduce in detail the types, characteristics, working principles and application scenarios of coating fans.
Types of painted fans
There are two main categories of coating fans: indoor type and outdoor type. Indoor painting fans are generally installed at the top of the paint shop and feed air into the coating equipment through pipesThe outdoor painting fan is installed directly outdoors and does not require ducts. In addition, according to the different air flow directions, coating fans are divided into positive pressure fans and negative pressure fans.
Indoor painting fan
Indoor coating fans generally use centrifugal fans, which have the characteristics of low noise, large air volume and moderate pressure. It sends fresh air into the coating equipment through the pipes to provide sufficient oxygen to the painted workpiece and ensure the smooth running of the painting process. Indoor coating fans can also be equipped with filters to effectively remove dust and harmful gases from the air and improve the quality of coating.
Outdoor painting fan
Outdoor coating fans generally use axial flow fans, which have the characteristics of small size, large air volume and high noise. It is installed directly outdoors without the need for ducting, which can conveniently provide sufficient air flow to the coating equipment. Outdoor coating fans are generally made of anti-corrosion materials and are suitable for places with various corrosive gases.
Positive pressure fans and negative pressure fans
Positive pressure fans and negative pressure fans are two fans with different flow directions in the painted fans. The positive pressure fan blows air to the inside of the coating equipment to maintain a certain positive pressure on the surface of the workpieceThe negative pressure fan pulls the air out of the coating equipment to maintain a certain negative pressure on the surface of the workpiece.
