SENTRY dampeners are pressure vessels containing a flexible bladder or bellows inside that separates
an inert pressurized gas (air or Nitrogen) from a system fluid in the lower chamber. Depending on how
dampeners are configured, they are used as P

to control pressure fluctuations and spikes in liquid piping systems.
Dampeners work on the principle that volume is inversely proportional to pressure (P1V1=P2V2).
Compressed air or Nitrogen (
never
Oxygen) is introduced into the non-wetted side of the dampener. The
gas charge is contained by the bladder or bellows preventing contact between the system fluid and the gas.
When the dampener is sized correctly, properly installed and charged according to the instructions
provided, it will greatly reduce the damaging effects of pressure variations in piping systems and
significantly improve the efficiency of transferring liquids.
All dampeners manufactured by BLACOH use pressure bodies made in the USA to insure quality.
Prior to shipment, each and every dampener is factory tested at design pressure or higher to assure
proper function and leak-free operation.
