Features
Mountz Cleanroom HVG (High-Vacuum Grease) Screwdriver models For highly sensitive applications in ultra-high vacuum and optics, Mountz offers HVG cleanroom screwdrivers with a specialized ultra-high vacuum and exceptionally low vapor pressure to prevent further airborne contamination and sustain lubrication performance. Our ultra-high vacuum grease is crafted using advanced polytetrafluoroethylene. It’s characterized by ultra-low outgassing, vast temperature suitability, and superb lubrication. It is an ideal choice for diverse chemical interactions because it is chemically inert, non-toxic, and nonflammable.
• Added resistance to extreme pressure • Performs well in harsh environments • Improved performance over time For FGA cleanroom models: 20,000 cycles before re-calibration
Calibration Intervals Routine Maintenance Intervals Compatible Cleaning Solvents
For all HVG models: 5,000 cycles before re-calibration
For FGA cleanroom models: 100,000 cycles
For all HVG models: 50,000 cycles
