AJVS Exhaust Silencer Kit-small Footprint Version for IDP 3 Scroll Pump, Special 3/8" NPT female x 1/4" NPT connector, included in the KIT

AJVS exhaust silencer kit for the IDP series Dry Scroll Pumps reduces the total sound pressure level due to exhaust pulsation, mitigates audible noise in the most sensitive frequencies, and collects tip-seal dust using a five-micron filter element.

Replace the 5-micron filter element after every tip-seal or module change

Performance:

Typical reductions are: 2.5 dB(A) measured at 1 m from the front of the pump, on a horizontal direction and an average of 1 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.
