EASILY HANDLES DIRT AND MOISTURE-LADEN AIR

  • Variable reactive damper provides an unobstructed free-flow air passage to reduce noise caused by emanating raw exhaust air
  • Unique design uses a proven reactive principle of noise suppression
  • Explosive force of exhaust air impacting against the damper thrusts it into an oscillating motion, converting dynamic acoustic energy into kinetic energy
  • Damper’s responsive pulsating motion drains off kinetic energy, dissipating acoustical energy
  • Ideal for foundry equipment and railway and transit brake systems
  • Recommended for pressures up to 125 psi (8.6 Bar)
