         13 . A set of ventilation units according to  claim 12  wherein said surface is arranged to form an interference fit with the at least one formation when the at least one formation is received within said space. 
     
     
         14 . A set of ventilation units according to  claim 12  wherein the at least one formation and the at least one co-operating formation are engageable by slidably receiving the at least one formation within said space of the at least one co-operating formation. 
     
     
         15 . A set of ventilation units according to  claim 12  wherein the at least one formation has a longitudinal axis that is substantially perpendicular to said surface of the first ventilation unit and said axis is substantially parallel to the longitudinal axis of said space defined by said surface of the at least one co-operating formation when the at least one formation is received within said space. 
     
     
         16 . A set of ventilation units according to  claim 1  wherein the first ventilation unit is stackable on or against the second ventilation unit and wherein the at least one formation and the at least one co-operating formation are arranged to be mutually engageable both when stacking the units in an aligned arrangement, wherein respective lengthwise ends of the first and second units are substantially aligned, and when stacking the units in a lengthwise staggered arrangement. 
     
     
         17 - 18 . (canceled) 
     
     
         19 . A set of ventilation units according to  claim 1  comprising a spacer element arranged to provide said intervening space.
