A plain filter for a 4-inch axial fan is designed to be used in conjunction with the 4-inch fan for cooling applications.

It operates at 220/240 VAC and is specifically designed to fit the 4-inch axial fan. The filter is made of high-quality materials that effectively trap and remove dust, dirt, and other particles from the air that passes through the fan. The filter helps to maintain the performance of the fan by preventing the accumulation of debris on the blades, which can reduce the fan’s efficiency and lead to overheating. The plain filter is easy to install and replace, ensuring that the fan continues to operate effectively and efficiently. It is commonly used in electronic devices, computer systems, and other equipment that requires efficient cooling with clean air to maintain optimal performance.
