ETS-Lindgren's SRFSD -F/A-100 and SRFSD -F/A-100ABS Sliding Doors are designed and manufactured specifically for anechoic chamber applications, according to the customer's requirements. These doors  maintain the same high shielding performance level as the standard smaller RFD-100 and RFSD-100 doors. 

No electric filters are required for the SRFSD -F/A-100 or -100ABS door systems. The outside of the door is equipped with safety edges, warning lights and buzzers to ensure user safety. The door can be supported from the chamber's frame, or it can utilize separate supporting structure, with the latter one being the standard solution. Please note: when the vertical structure above the door is inaccessible, it most likely requires redesign and stiffening of the construction where the upper part is supported.

To guarantee and maintain the high shielding performance of the door, it is essential that the installation is carried out according to the instructions and under ETS-Lindgren supervision, with maintenance instructions being carefully followed.
