Better quality to l%u2019air and higher effectiveness of ventilation
Heat exchanger of high capacity out of aluminum: economy d%u2019énergie by recovery of optimal heat, more effective thermal conductibility and very weak pressure losses Wheels of fan in figure arched with l%u2019arrière: best performance, high strength to l%u2019encrassement, facilitated cleaning and long life of life
Engine with D.C. current: low power drain and quiet operation
Volumetric adjustment with constant flow ordered by pressure with function of filter and antifreeze Operates by remote control without wire with timer, installation without wiring
Commutation be automatic with complete return to l%u2019air external out of standard
