Extend the Life of your Hydraulic Elevator System! The MEI Silencer is an in-line device that reduces the noise and vibraon of any hydraulic power unit (similar to the muffler on an automobile). Reduced Pulsaons = Reduced Noise, Leakage, and Component Wear. Pump pulsaons cause vibraons. Transmied by the piping throughout the system, vibraons cause noise, leakage, and early component failure. When the MEI Silencer stops the pulsaons, it stops the source of the vibraons. This improves system performance and reduces service calls, pleasing your client and improving your reputaon. Benefits • 40-60% reducon in system noise and vibraon • Extended component life • Fewer leaks • Lower long-term system maintenance costs • Smoother system operaon How it Works Hydraulic pulsaons (noise) enter the silencer and go through three different noise baffles or diffusers. Aſter passing through these baffles, the pulsaons then strike a rubber tube, or bladder, charged with air to 35% to 50% of the hydraulic operang pressure. Hit by a pulsaon, the bladder deflects slightly, reducing the size of the pulsaon and therefore, the noise. Recommended Applicaons • Dry or submersible hydraulic power units for all hydraulic elevator car types. Part No. Descripon A B C 19316 Silencer 2” GRV x 2” GRV (100 max.
