One way to improve the efficiency and profitability using powder coating is the recovery (return) of the powder paint carried away with the flow of ventilation. It is known that in the best case, only 60-70% of the paint deposited on the product. From 30-40% of unused paint only a minority remains on the walls and bottom of the chamber spray, and the bulk of unused paint carried away ventilation. Given the high cost of paint, it is not difficult to calculate the economic effect of recovery.

One of the primary recovery methods is the use of cyclones. Recovery of paints is due to centrifugal force in the upper cylindrical part of the cyclone and the powder deposition on the bottom of the cyclone. Properly designed cyclone permits to collect 90% of the airborne paint with particle size greater than 2.1 microns. Application output filter after the cyclone allows you to return the cleaned air directly to the shop, which has a positive effect on the economy of heat transfer for heating in winter, given that the approximate air consumption Dual Post camera spray of 8-12 thousand cubic meters per hour.

It is worth noting that in addition to high efficiency cyclone, they have some disadvantages. One disadvantage is the difficulty of cleaning the duct of the cyclone, and when changing paints. The solution to this problem is to use shortest possible duct with the possibility of opening the ducts for wet and dry cleaning, and a device for such cleaning hatches at the cyclone.

Our specialists will help you to correctly calculate and make recovery systems and air aspiration based on the use of cyclones.
