The AP/AM/AE/AER spring driven hose reels are naturally used for the suction of exhaust gases as the suction takes place directly from the emission source.
Principle of operation
The suction inlet is applied to the vehicle exhaust pipe. The sucked exhaust gas runs through the winders' reinforced rubber hose, until it reaches the main intake manifold. The necessary vacuum is produced by a centrifugal fan, which will expel the air into the atmosphere.
As the suction inlet is positioned directly in the exhaust gas production source, only the contaminated air will be expelled. Therefore this will avoid wasting energy, especially during the winter season.
