In the previous article, we compared the functional advantages and disadvantages of the automatic rolling curtain air filter and the plate-type primary filter, but there must be users who feel that the unit price of the winding filter is too high, and they are unwilling to design the automatic winding in their own ventilation filter system. The filter case.

1Comparison of initial investment cost: The initial investment of Nanjing Ecolead automatic roller shutter filter is relatively large, and it is necessary to purchase a complete set of equipment including automatic PLC control system and motor transmission parts, and the initial effect only needs to purchase the plate filter and the corresponding modularization. Fixed frame, the initial effect filter was put into the initial stage to win the wind filter

2 Comparison of operating costs: The automatic roller shutter filter only needs to replace the special filter cotton in the later stage. The price of a roll of cotton is generally less than 1,000 yuan, which can meet the needs of one year. However, the plate-type primary filter is discarded as a whole piece. The size of the cross-sectional area is different, and the price of a replacement will exceed 1,000 yuan, plus the cost of personnel maintenance. The winding filter is better than the primary filter with its low cost of replacing the filter cotton.

It can be concluded that although the unit price of the coiled filter is high, the initial investment cost is high, but as the user’s use time passes, generally after 2-3 years, the cost of the two will be the same, and the later coiled filter With its complete control system and low filter material replacement cost, it stands out in the primary filter family and completely wins.
