mode). This condition continues until the power required
drops below 750 Watts.
The target frequency is stored in the inverter even when
power to the pump is removed.

Purge Kit

A purge kit (Agilent part number PTSPURGEKIT) is
available to properly purge either the bearing purge or the gas
ballast. This kit contains a flowmeter and all necessary
valving and tubing.

Exhaust Silencer Kit

In certain applications it is desired to lower the noise level
emitted by the pump. For these cases, Agilent offers Exhaust
Silencer Kits (P/N EXSLRTRISCROLL, Manual P/N:
699904380), which breaks up noise pulsation in the discharge
line.
The Exhaust Silencer Kits contain two basic components, as
well as installation hardware. A cylindrical resonator chamber
has been selected to attenuate the frequencies associated with
the exhaust gas pulsation noise. The resonator is then
plumbed to an exhaust muffler/filter. This muffler provides
the majority of the actual noise reduction. It also contains an
integral 5-micron paper filter element to capture any tip seal
debris. This paper filter is replaceable; the recommended
service interval is whenever the pump tip seal or module
maintenance is performed.

Vibration Isolation Kit

A set of vibration isolation mounts (P/N PTSVIBISOKIT,
Manual P/N: 699904385) are available for Agilent scroll
pumps. These are used in place of the standard feet installed
on the pump for applications that require minimal vibration
transmission from the pump to the installation. They can be
used alone, or with inlet flexible bellows to provide pump
isolation.
The vibration isolation mounts in the Vibration Isolation Kit
have been designed to ensure the lowest vibration level
transmitted at the base of the pump.
Vibration level in every direction (axis), transmitted to the
surface the pump sits on, is reduced by a significant amount.
Typical vibration reduction levels are 75% for the TriScroll
800 pump.
The TriScroll Vibration Isolation Kit consists of (4) vibration
isolation mounts. They have a M6 metric threaded screw to
attach to the TriScroll frame; the screw is provided.
These mounts increase the height of the TriScroll pumps by
0.75" compared to the standard mounting feet.

HEPA Inlet filter

Agilent now offers inlet filters for the scroll pumps, which
protect the pump from ingested particles, and keep particles
from migrating out of the pump. These HEPA filters provide a
rated 99.97% efficiency in trapping particles > 0.3 microns.
