What noise reduction can I expect from the Brass Silencer with Choke MWSVL and GZ at 5 bar, 1 m, 45°?

Brass Silencer with Choke MWSVL and GZ: At 5 bar supply pressure, measured at 1 m distance and 45° from the silencer axis, you can expect an average noise reduction of around 25 dB (actual reduction varies by size).

How does the Brass Silencer with Choke MWSVL and GZ perform at different supply pressures (e.g., 3 bar vs 7 bar) in terms of noise reduction and flow restriction?

Brass Silencer with Choke MWSVL and GZ performance varies with supply pressure mainly in two ways: noise reduction and flow restriction. - Noise reduction: The silencer’s specified average reduction is ~25 dB at 5 bar (measured at 1 m, 45°). At lower pressure (e.g., 3 bar) noise levels from the exhaust are lower to begin with, so you can expect similar or slightly better perceived reduction in dB, though absolute sound energy is reduced. At higher pressure (e.g., 7 bar) exhaust noise energy increases, so measured dB reduction may be slightly less than the 5‑bar reference; however the MWSVL’s design still provides substantial attenuation across the operating range up to its 12‑bar limit. Exact dB change depends on size and installation. - Flow restriction: The integrated choke (throttling) imposes a pressure‑dependent flow restriction. At 3 bar the flow through the choke is lower and pressure drop across the silencer is smaller in absolute terms; at 7 bar flow (and thus mass flow) is higher, producing a larger pressure drop and greater relative restriction. Larger MWSVL sizes reduce the restriction effect; smaller sizes increase it. The silencer remains serviceable up to 12 bar and within −10°C to +80°C, but expect increased pressure drop at higher supply pressures and when using smaller sizes. In summary: Brass Silencer with Choke MWSVL and GZ will still deliver strong noise attenuation near the stated ~25 dB around mid‑range pressures, with somewhat better apparent reduction at lower pressures and somewhat increased masking of performance and higher pressure drop at higher pressures; size selection determines the trade‑off between noise reduction and flow restriction.
