AIR POWERED RAMMERS

Looking for an alternative power source to operate your tamping rammer? An air rammer can be an ideal choice for you.

Equipment Synergy International provides a range of air powered or air motor-powered jumping jacks that can meet your exact requirements. Our air rammers are perfect for those applications where a spark-operated motor is not desirable due to fire risk.

ESI air-powered rammers require only 60 CFM of air and are powerful enough to help alleviate the problems related to engine exhaust in a congested building.

ETR50A Air Powered Rammers

Examples of applications where an air-powered rammer would be desirable:

  • Inside of buildings where engine exhaust will be a problem
  • Down in deep trenches where engine exhaust can accumulate
  • Use in oil refineries where spark-operated equipment may not be desirable
  • Use in place of an electric rammer and not worry about electric cable length or voltage line loss – and much safer!

To service between uses requires only a quick wash and checking of the rammer bottom oil reservoir – that’s it! No engine to service which also eliminates many of your typical rammer service issues.
