Buying Guide for Vacuum Pumps
When selecting a vacuum pump for making plasma or neon displays, consider the following factors:
1. Type of Pump
There are various types of vacuum pumps, including rotary vane pumps, diaphragm pumps, and scroll pumps. For plasma displays, a two-stage rotary vane pump is often recommended due to its ability to achieve low pressures.
2. Ultimate Pressure
The ultimate pressure of a vacuum pump is a critical factor. For neon lights and plasma displays, a pump that can reach pressures of 10 microns or lower is ideal. This ensures that most of the air is removed, allowing for a clean gas fill.
3. Pumping Speed
Pumping speed is measured in cubic feet per minute (CFM). A higher CFM means the pump can evacuate air more quickly, which is essential when working with glass that needs to be heated to drive out moisture.
4. Oil vs. Dry Pumps
Oil-sealed pumps can provide better vacuum levels but may introduce oil vapor into the system. Dry pumps eliminate this issue but may not achieve as low a vacuum. Consider your needs and whether oil contamination is a concern.
5. Budget
Vacuum pumps can range from affordable to high-end models. Determine your budget and look for a pump that meets your requirements without breaking the bank.
