The production process of the filter is complex and the raw materials are expensive, but it is easy to use and can be used continuously. Therefore, the price is not high when carrying forward. The key is that people often use work clothes and automatic welding machines. If employees are skilled in technology, the price will be very low. If it is a non-standard model and specification, people still need to develop new grinding tools, and the cost will be higher.
In order to improve the efficiency and economic benefit of medium efficiency filter, it is particularly important to prolong the service life and improve the maintenance. In the whole application process, the technical operation procedures must be strictly implemented, and the cost plan management method of the filter must be implemented. Then it can play the role of active maintenance in daily maintenance.
