CapacityFresh air ventilation and heat exchange unit SAF-E4Model No.SAF250E4SAF350E4SAF500E4SAF800E4SAF1000E4Installation referencePipe HoodOutside Intake DuctCeiling Suspension BoltSupply <strong>Air</strong> DuctThe SAF recovers heat energy which would otherwise be exhausted toatmosphere, and uses this energy to warm the air entering thebuilding. The reverse happens in warmer climates, where theexhausted cool air is used to partially cool the incoming air.Capturing this waste energy, means the heating/ cooling requirementsof the building are reduced, so smaller size plant can be selected,savings can be made in long term energy consumption, and carbonemissions are reduced.OA(Outside <strong>Air</strong>)EAExhaust<strong>Air</strong>Room Intake DuctHeat InsulationMaterialExhaust <strong>Air</strong> DuctRA(Room <strong>Air</strong>)Room Intake Opening(Supply/Exhaust <strong>Air</strong> Grill)SA(Supply <strong>Air</strong>)Inside Supply Opening(Supply/Exhaust <strong>Air</strong> Grill)The inclusion of the SAF energy recovery ventilation units in thebuilding design, will reduce the total amount of carbon emissions.Structure (SAF1000E4)Principle of operation (simple ventilation)FREE COOLINGPrinciple of operation (heat exchanging)ENERGY RECOVERYPlate heat exchangerDamperExhaust <strong>Air</strong>outdoorindoorSupply <strong>Air</strong>Exhaust <strong>Air</strong>outdoorindoorSupply <strong>Air</strong>EA(Exhaust <strong>Air</strong>)RA(Room <strong>Air</strong>)27deg10deg33deg29degOutside <strong>Air</strong>Room <strong>Air</strong>Outside <strong>Air</strong>Room <strong>Air</strong>10deg27deg35deg27degOA(Outside <strong>Air</strong>)SA(Supply <strong>Air</strong>)e.g. For coolingin winter timeItem Model SAF250E4 SAF350E4 SAF500E4 SAF800E4 SAF1000E4Power source1 Phase 220-240V, 50HzExterior dimensionsHeight x Width x Depth mm 270x882x599 170x882x804 270x962x904 388x1322x884 388x1322x1135Exterior appearanceGalvanised steel sheetPower inputW 99-114 124-137 169-188 309-359 360-399Running current A 0.46-0.48 0.59-0.60 0.79-0.81 1.48-1.50 1.85-1.93Enthalpy Cooling 63 66 62 65exchangeUHi efficiency Heating 70 69 67 71Temperature exchange efficiency 75Enthalpy Cooling 63 66 62 65exchangeHi efficiency Heating %70 69 67 71Temperature exchange efficiency 75Enthalpy Cooling 66 69 77 68 68exchangeLo efficiency Heating 73 71 67 74 73Temperature exchange efficiency 77 77 75 76 76Motor & Q’ty kW 0.02x2 0.044x2 0.062x2 0.117x2 0.137x2<strong>Air</strong> handling equipment Fan type & Q’ty Sirocco fan x 2UHi 250 350 500 800 1000<strong>Air</strong> flow Hi m 3 /h 250 350 500 800 1000Lo 170 280 370 650 810UHi 90 95 105 140 90Available static pressure Hi Pa 80 65 70 110 55Lo 37 42 38 70 35Remote controlStandard equipment<strong>Air</strong> filterOut take intake airExhaust airProtection for element (Washable) PS40023
