NBC Dampers

PECOL Ltd. since 1978 designs, builds and installs on board of naval military units, NBC dampers, anti shock, non magnetic, watertight to a flow of air up to an hydrostatic head of 1,500 mm H2O, divided into two types:
• fixed dampers
• swivel dampers

The fixed dampers can be housed either inside a ventilation duct, both at its root, in the vicinity of the air intakes, or of the filters NBC, or directly on the superstructure according to the characteristics of radar protection of the ship.

The swivel dampers are pre-arranged in factory with female clevis, both on left than right side, for installation on a frame welded to the superstructure, through male hinges.

They can rotate either towards the external or to the inner of the ship
