Supra uses walls to trasport the air to floor level. Settings of the air direction is done after finished installation. Learn more about the InventiAir technology on inventiair.com Step 1 - Mount the connection box Step 2 - Mount the air diffuser • • • The connection box is fixed to the ceiling structure with mounting brackets or threaded rod in the box brackets. The connection box is connected to the duct system in the selected end with a nipple connection (the adjustment plug is pushed into the other end). • • 1 The air diffuser is placed in suspended ceiling grid system (standard c/c 600 T24). The air diffuser can also be mounted below the roof carrier profiles if concealed grid system is used. The distance between the connection box and the diffuser can be extended by a circular duct. 2015-11-16 10 Mounting descriptions SUPRA Step 3 - Adjusting the flow Step 4 - The air diffuser (adjustments) The adjustment plug is placed in the diffuser to the desired setting for custom flow and is readout on the inside of the tube. NOTE! Be sure that the adjustment plug appear straight and precise at each setting. The air diffuser is directed against the nearest wall to achieve an efficient operation. Setting 6 Setting 4 Setting 1 Care/cleaning The air diffuser is cleaned, if necessary, with a damp cloth or with the vacuum and the brush attachment. • • The pressure measured in the outlet. When the correct value is obtained, the cover is putted back and seal the tube (is not needed at the fully open position). 2 2015-11-16 10 Mounting descriptions SUPRA Capacity- & adjustment chart (k-factor per nozzle is 0,014) 1 Setting: 2 3 4 5 6 7 8 9 100 30 90 80 Sound level Lp dB(A) 150 70 25 60 Pressure (Pa) 50 40 30 1 2 3 4 5 6 7 8 9 10 20 30 40 50 60 Airflow (l/s) Every nozzle have a k-factor = 0,014. To calculate the amount of active nozzles for the preferred pressure and air flow, use the formula “Amount of acive nozzles” = Qs/ (K*√∆P). Qs = applied airflow, K = k-factor, ∆P = available pressure in the nozzles Correction of sound pressure level (Lp) to the sound power level (Lw) in each octave band* Supra use nozzles designed to provide high accuracy, while these provide low noise levels even at high operating pressures. This gives you a quiet diffusers with a wide working area. 63 125 250 500 1000 2000 4000 8000 Hz -14 -10 -8 -5 -3 -7 -10 -10 Natural attenuation in octave bands* 3 63 125 250 21 19 15 500 1000 2000 4000 8000 Hz 8 8 9 3 1
