Abstract: A silencer device may be positioned in-line with an exhaust tube of a pneumatic pump to reduce a noise generated at the exhaust tube. The silencer devices includes a noise absorbing media and a body section housing the noise absorbing media and radially sealing peripheral walls thereof. The silencer device also includes a fluid inlet section having an inlet tube that directs fluid flow from the exhaust tube into the noise absorbing media and an inlet airflow restrictor fluidly connected to the fluid inlet section to restrict fluid flow therethrough. The silencer device further includes a fluid outlet section having an outlet tube that directs fluid flow from the noise absorbing media and an outlet airflow restrictor fluidly connected to the fluid outlet section to restrict fluid flow therethrough.
