The standard construction for fan powered supply or extract airunits includes sound insulation lining backdraught damper and radial flow fan . The control of the unit can be by a threeposition rocker switch (0/1/2) or by external switching supplied by others. The two stage fan provides a choice of flow rates as follows 30/40/50/60/80 m > 3 /h. Potentiometers are used to achievethe adjustment. Thus flow rates can be changed to reflect sub- sequent changes in the division of the internal space.
