4 COLLECTIVE VENTILATION Ventilation unit PULLEY/BELT TRANSMISSION 4 to 114 m 3 /h C4 EXTRACTION UNIT DESCRIPTION CTICM C4-4 C - 1/2 h approved Report no. 9-E-4 CSTB technical notification for Hygro A, Hygro B and Hygro Gas usage CMV POWER APPLICATION selection software APPLICATION Intended mainly for air extraction in houses and public assembly buildings requiring average and high flow rates at low consumption constant pressure. C4, 4 C 1/2 h certified. 23 V SINGLE PHASE 5 Hz and 6 Hz power supply. Econological solution : maintaining the installation at constant pressure over the whole of the flow rate range of the unit provides low energy consumption since the fan rotation speed will be adapted instantaneously to the requirements of the installation. The energy consumption gains thus obtained are of the order of 3 to 6%. Operating the installation at constant pressure at reduced flow rate also lowers the sound levels radiated by the system. GAMME Comprising 1 models, it covers flow rates from 4 to 114 m3 /h in a number of configurations. INSTALLATION Can be installed internally or externally. Easy access to all internal parts. May be fully dismantled CONSTRUCTION Housing: galvanized steel sheet. Amply dimensioned, it offers powerful air handling and acoustic performance characteristics. Internal access via two removable panels. Bird protection grid on discharge. Two circular branch connections with double lip seals. LOBBY unit IP fitted with a speed controller and a pressure sensor with signal integrator fitted and wired as standard. Setpoint pressure adjustable via the console built in to the LOBBY unit. Factory set to 18 Pa. Local padlockable switch on front panel. External pressure tap to check air flow. The incorporates an air flow defect relay. This is programmed using the following information: Defect: contact signal if pressure less than 5 Pa. Mistral 3 S: time delay of 3 secs on the defect contact in order not to trigger spurious alarms Indicator light: a contact is available for connecting a green indicator light showing the unit is in operation. Vibration pads incorporated under the chassis of the motorised fan unit. SILENCE version 4 C 1/2 h certified. The insulation of the unit using 25 mm M eral wool allows acoustic performance characteristics compliant with the requirements of the new regulations to be achieved. MOTOR FAN Transmission by pulley and belt, motor pulley variable when stopped. Three-phase one-speed motor, IP55 class F, 23V/1/5 Hz. Door opening sensor available for office ventilation. Centrifugal impulse turbine with double opening. Flexible connection from turbine to unit. Spare belt supplied. The units are available in two versions: H: 1 horizontal intake Ø D1 + 1 horizontal discharge Ø D2 in-line V: 1 horizontal intake Ø D1 + 1 horizontal intake Ø D2 + 1 vertical discharge LxL1 For the dimensions of the NOE LOBBY, refer to the table on page 21.
