2G / QB Series: Enhanced Filter Silencers for Blowers, Compressors, and Fans

2G Series: This compact multi-stage premium filter silencer is readily available for North American users. Primarily used on PD blowers, the filter silencer has a compact size that minimizes the overall blower package footprint. In addition to traditional silencing tubes, the premium silencing features include a singular high flow attenuation tube in the base. The heavy-duty quiet band technology in the weather hood helps reduce noise escaping the inlet of the blower, compressor, or fan.

QB Series: This heavy-duty filter silencer has integrated silencing tubes that reduces noise. It also boasts an enhanced weather hood with quiet band technology that reduces noise escaping the inlet of the blower, compressor, or fan. It is available in metric threaded or flanged configurations.
