Free area correction factor f 1 Free Area Factor To calculate the free area, the grille s nominal area is multiplied by f 1, where f 1 is a correction factor and is determined by the graph. For single deflection the nominal size is the grille s Y dimension. For double deflection it is the grille s X dimension. Example: Size 0 x 1 single deflection. From the graph, f 1 = 0.79 for the grille height of 1. The grille s free area is therefore: 0/00 x 1/00 x 0.79 = m 2. For a double deflection include the factor f 1 for the grille length. The free area would therefore be: 0/00 x 1/00 x 0.79 x 0.80 = m 2. Correction Factor Nominal Size Page. 3

120 2.63 APR PERFORATED CIRCULAR DIFFUSER Description The 2.63 (APR) is a circular perforated supply air diffuser for mounting in ceilings where exacting requirements for draught free conditions are necessary, such as in schools, offices and hotels. The air is supplied partly through the perforated side. This type of construction gives the device a high degree of induction and makes the 2.63 model suitable for systems with variable air flow, or for installations where air has to be supplied with a large negative temperature and short throw. The design provides a fully radial pattern and minimises the occurrence of dust accumulating on the ceiling. The 2.63 model can be ceiling mounted or directly mounted into exposed ductwork.

165 4.11 AMU END-LINE DUCT MEASURER Description The end-line measurer is a fixed air measuring device for mounting in circular ductwork. It provides a very simple and highly accurate method of measuring the air flow. The air flow rate is determined by measurement of the differential pressure across the mid mounted sensor then cross referenced to the diameter of the end-line measurer. Sound data NR levels for the diffuser may be determined from the engineering graph. Sound power level L w The generated sound power level L w db is calculated by adding the correction factor K ok (see table below) to the sound level NR db according to the formula: L w = NR + K ok Frequency (cycles per second Hz) Size Tol +/ Page. 2

210 POLYFAB R1.0 DUCT 5.26 AFPB Description Polyfab ducting is made from a black laminated fabric with an external metal helix formed to clamp the edges of the fabric in a mechanical lock. No adhesives are used. The metal helix gives the duct strength durability and scuff resistance. The duct is insulated with a polyester blanket (R value of 1.0 m 2 W/K) which is protected by a outer vapourbarrier sleeve. The duct assembly is lightweight, easy to handle and extremely flexible, Fabriflex ducting can be compressed to less than a quarter of its normal extended length. The duct is suitable for both high and low pressure heating ventilation and air conditioning systems.
