2G / QB Series: Premium Duty Blower Filter Silencers

2G Series: This compact multi-stage silencing filter is readily available for North American users. Primarily used on PD blowers, the compact size helps minimize overall blower package footprint, thereby reducing a variety of costs. The multi-stage silencing feature reduces noisy environments created by the blower package.

QB Series: This heavy-duty filter silencer has integrated silencing tubes that reduce noise attenuation, and an enhanced hood that minimizes package vibration. Available in metric, threaded, and flanged configurations.
