Performance
Typical reductions are: 4 dB(A) measured at 1 m from the front of the pump, on a horizontal
direction and an average of 3.8 db(A) from all three directions, under a 2-3 Torr load, and
with the gas ballast open. The exhaust silencer kit does not significantly influence the sound
pressure when pumping at base pressure.
The kit’s silencer/resonator assembly mitigates exhaust pulsation noise in the most sensitive
frequencies.
If the smaller footprint version is adopted, the silencing performance is slightly diminished,
and the low frequencies are not as successfully mitigated as with the full version.
Maintenance
Replace the 5-micron filter element after every tip-seal or module change.
