Fire DamperSMA-D1

  • Designed to prevent fire from spreading into fire-protection zones.
  • Installed in fire-rated partitions or walls.
  • Structure remains open during normal operation; in case of fire, the fusible link melts, causing the blades to close automatically.
  • Air volume adjustable via handle.
  • Available materials: Stainless Steel (SUS), Galvanized Iron (GI).

Volume Control DamperSMA-D2

  • Damper capable of adjusting air volume via a handle.
  • Commonly referred to as an “Air Volume Damper,” used generally for controlling flow rates in HVAC ducts.
  • Attached to Air Handling Units (AHU) or used for airflow control within ducts.
  • Available materials: Stainless Steel (SUS), Galvanized Iron (GI).

Air Tight DamperSMA-D3

  • Damper designed to maximize air tightness.
  • Used when complete air shut-off (isolation) is required.
  • Available materials: Stainless Steel (SUS), Aluminum (AL), Galvanized Iron (GI).

Ventilation Duct HoodSMA-D4

  • A duct system that transports contaminated air from the hood through an air cleaning device to the fan.
