Revolving air curtain
Airbloc, part of Nortek Global HVAC (UK), has developed a range of commercial/retail revolving-door air curtains, designed to give a neat and discreet solution to prevent continuous draughts but still let in a certain amount of outside air at every rotation.
The ACRD consists of a unit and an exhaust duct adapted to the shape and colour of a revolving door. The front of the duct is covered by a panel that is available in polished high gloss, polished or brushed steel, and powder-coated steel.
