Welded static pressure chambers of any shape
Our KSDs are made of black metal and coated with powder polymer paint. The hermetic design of the KSD reduces system noise, minimizes pressure losses, and allows the use of FLOW diffusers in rooms with high humidity. Adding antistatic or antibacterial components to the paint makes it possible to use the equipment in children's and medical institutions.

Non-standard angles
