Why Place Tapped Exhaust Ports on Pneumatic Industrial Vibrators?

By CVC Team

Back in the 1960s, Cleveland Vibrator Company (CVC) started to move away from the acceptable industry standard of the time and started to manufacture vibrators with tapped exhaust ports. Today a large part of our vibrators, including 100% of our Vibra-Might family group, have threaded exhaust ports. The primary reason for the threaded exhaust ports is to install our port protector/muffler in the port. The port protector has two primary functions. One is to prevent impurities from entering the vibrator through the exhaust port. Secondly, it helps reduce some of the noise emanating from the vibrator as it vibrates. The tapped exhaust also allows for connecting a hose to pipe the air away in cases where contamination of the area is not acceptable, such as food grade areas or inside a controlled environment. Our units have even been used under water!

There are other applications where the exhaust port protector was removed and replaced with an adjustable speed control muffler to regulate the speed of the vibrator. In rare cases, customers have used the exhaust ports to operate a second vibrator off of the exhaust air from the first unit. This is American ingenuity at it’s best, for sure. It is my opinion that a tapped exhaust gives you more options and does a better job of protecting the inside bore of our vibrators than those that are just drilled through exhaust holes.
