Gaisa filtrs Doppler Venturi 2010 balts

Doppler Air Filter Venturi 2010 white. The Venturi Air System by Doppler is one of the most advanced systems in racing air filter development. The stand-out feature and benefit of this system is the use of the so-called Venturi effect. The diameter of the intake area is tapered down gradually to reduce the initial suction required to start air flow and increase air flow velocity. This is very helpful in 70cc engines where suction is not very high to begin with. The air flow is directed into a resonance chamber via a Venturi insert, this resonance chamber has the combined advantage of reducing intake noise and fuel vibration – the carburetor will run more smoothly and can be adjusted a lot easier.

The Doppler Air Filter Venturi is suitable for 12mm – 21mm carburetors; it comes with a second insert for 19-21mm Dell’Orto and Arreche carburetors.
