  • The channel is made of three pieces of panels made of galvanized sheet metal th. 0.8 mm.
  • The dimensions of the duct depend on the air flow, the depth from 200 to 400 mm and the width of the duct is 300-600 mm.
  • The air grille is located at the bottom of the duct.
  • The lower edge of the air duct is 300 mm from the clean floor, the upper edge of the duct is 50 mm above the ceiling.
