What are the main differences between the Overarm Dust Collection (TSA-ODC) and the Floating Dust Collection (TSG-FDC)? There are a few key differences that separate the TSA-ODC Overarm Dust Collection and the TSG-FDC Floating Dust Collection Guard. Here are the most important ones: The TSA-ODC is an assembly of tubing and fittings that connect to the TSG-DC Guard. The TSG-FDC is a combination of guard, tubing and fittings that does not connect to the TSG-DC guard. The TSA-ODC has narrow-diameter tubing for high-velocity, low CFM extraction, and connects to the 4” port at the back of your cabinet saw. The TSG-FDC has wide-diameter (3” to 4” steel) tubing for mid-velocity high CFM extraction, and requires its own 4” connection to the right of your saw’s extension table. The TSG-DC guard (required to use the TSA-ODC) is splitter-mounted to the saw trunnion. The TSG-FDC floats above the table, with no splitter mount. This enables the user to keep the guard in place for non-through cuts (dado, etc), and to swing the entire guard/tube assembly clear of the saw table when necessary. The height of the TSG-FDC guard above the table/workpiece must be adjusted by the user, while the TSG-DC guard dynamically adjusts to each workpiece, helping to keep the blade guarded and optimizing dust collection.
