Designed to reduce the noise of aspirator pumps in the laboratories. The innovative triple chamber noise silencer dramatically reduces the noise generated by the aspirators hence saving the scientist headache by removing the annoying background noise in their lab. When connected to the air outlet of any aspirator pump, it reduces the unnecessary pump noise by 90%.

  • Innovative noise capture technology with no restriction to the air flow
  • Closed and sealed up body that requires no service or cleaning
  • No moving parts ensuring long lifetime
  • 10 years warranty.


One of the most common problems with the commercial aspirators is the noise they gradually start to make after a short period of time such as 6 months or so. This noise is inevitable and is something to do with the way these pumps generally work. Most of the commercially available aspirator pumps do not have these internal silencers so the users unfortunately have to live with the annoying noise they start to make as they become a little usage.


We have pump silencer of three sizes depending on the size and capacity of the aspirators.

Small is for bench-top aspirators, Medium is for the floor aspirators with 5L capacity tanks, Large is for larger than 20L tank or constant flow aspirators pumps
