Lobe type and multi-vane compressors generate high-energy noise levels at the fundamental and initial harmonic frequencies. With no absorptive pack, rugged construction and high quality materials, this multi-chamber design is tuned to handle these frequencies and is very effective in reducing tonal radiation from the pipe work connected to these machines.
Using a powerful computer design programs
Flo-Dyne are ableto predict and analyse the
performance of each silencer application.
Flo-Dyne engineers are able to adjust internal dimensions and observe the effects on performance to ensure optimum performance is achieved. to adjust internal dimensions and observe the effects on performance. Pressure vessel fabrication techniques are used with pressure ratings given. Carbon steel construction is standard, but other materials are available for special applications.
The graph shown below shows actual measured dampener performance that equates to over 30 dB reduction in pulsation level at the fundamental pulsation frequency and the first harmonic at a flow rate of 29000CFM @ 68°F from a rotary blower.
