In no time at all, DFPH-100 will enable you to divide a large space into smaller units. Thanks to our extensive experience with bearing technology and the rolling properties of a variety of different materials, we can find a high-quality, durable rail and trolley construction for every application that will also ensure optional ease of operation. (No Floor Track Needed.) 10 layers rubber seals set in male and female profiles will provide excellent sound insulation effect. If you need mobile walls with high sound insulation performance and the maximum height is less than 6 metres DFPH-100 is the best choice. The retractable top and bottom pressure seals connect firmly between the floor and the track to secure the different panels.
