Salt Water Resistance Option

Series 1500 damper with SW Option

SW Resistance Option:

  • The Salt Water Resistance Option was specifically designed for environments where there is salt spray or salt content in the air and/or where moisture levels are elevated.
  • Ideally suited for coastal climates.
  • Recommended for inland applications, where tire spray from winter-salted roads have been known to corrode dampers installed in close proximity to roads or highways.
  • The extruded aluminum frames and blades are all clear anodized to a minimum thickness of 0.7 mil (18 microns) deep.
  • The frame is assembled with stainless steel screws.
  • Stainless steel hardware, linkage parts and screws replace all zinc-plated steel components, providing protection against rust and corrosion.
  • All aluminum linkage hardware parts are clear anodized.
  • Blade and frame seals used for dampers with the Salt Water Resistance Option are extremely flexible extruded silicone.
