Manual LV Vent to Gas Purge Kit

For manual tempered venting to gas purge of LV systems.

Ball valve, metering valve, flow regulator, and pressure relief valve
Metering is manually set/adjusted

Automated LV Vent to Gas Purge Kit

For automated tempered venting to gas purge of LV systems.

Solenoid valve, metering valve, flow regulator, and pressure relief valve
Sequence and Timer control integrated into VCC (ordered separately)
Metering is manually set/adjusted

Manual UHV/HV Vent to Gas Purge Kit

For manual tempered venting to dry inert gas purge of UHV/HV systems.
Recommended for use in chamber pre-conditioning and contamination control procedures.
Recommended for use during power failure of automated UHV/HV system: Ideally, UHV/HV systems should be always be vented to dry inert gas purge even during power failure.
Metering is manually set/adjusted to prevent side-effects of too rapid a vent.
CF or QF flanges
High Vacuum valve, metering valve, flow regulator, and pressure relief

Automated UHV/HV Vent to Gas Purge Kit

Performance Specifications

All performance specifications stated, including but not limited to, pump-down rates and vacuum levels make the following assumptions:

The Vacuum Chamber is empty.
The Vacuum Chamber and other system components are clean and dry.
The System is being operated at Sea Level
The ambient temperature is 18°C +/- 2°C
All system components, including those not supplied by Abbess, are appropriate for the system and are functioning properly.
The specifications are not impacted by the properties of your product.

If you require performance specifications for conditions other than those listed above, it is vital that you make this known to Abbess Instruments in writing. Generally Abbess Instruments recommends choosing chamber and pumping system qualities capable of achieving a theoretical vacuum at least an order of magnitude better than the desired operational vacuum.

It is to be noted that a specification described as '10-5 Torr' is a range, and means the clean, empty, dry chamber system is capable of reaching some undetermined value between 1.0x10-5 and 9.9x10-5 Torr: The (clean, empty, dry) chamber is deemed compliant whether its As-Built base vacuum is 1.0x10-5 Torr or 9.9x10-5 Torr. It does not mean that the chamber is guaranteed to reach every level within that range.
