Common Questions about Vacuum Chambers
What are the advantages of a PV V&E chamber?
We know vacuum. All of our chambers are fabricated in-house by world-class vacuum welders. Because our chambers are manufactured in-house, Pfeiffer Vacuum Valves & Engineering have control at every step of the fabrication: design, manufacturing, electropolishing, RGA scans, bakeouts, vacuum testing, and shipping.
How can I reduce the cost of a custom chamber?
Peiffer Vacuum Valves & Engineering's team of engineers will work with you to reduce the cost of a custom-made chamber. Two easy methods to substantially reduce costs are:
- Reduce the tolerances on the drawing. Tighter tolerances = more production time and higher cost. Simply changing the default tolerance values in your CAD program can reduce costs immediately.
- Use standard components instead of custom-drawn parts. Standard off-the-shelf parts cost less. Working with standard fittings, tubing, elbows, and diameters will reduce the amount of custom work required on a chamber.
