Get the benefit of true anti-overflow security with the new DFS system. True security with reconditioning at the highest standard and most reasonable price yet achieved by an aspirator manufacturer. DFS means the best in aspirator safety over the longest lifetime.
Immediately a blockage is registered in the nozzle not intended for secretions, the system stops the suction process. The internal works are immediately and conclusively protected from contamination by this “overflow” situation, which is remedied simply by exchanging the DFS so that the unit can go straight back into use.
