Edwards Enables - Light Bulbs

One of the first applications of vacuum was for the ordinary incandescent light bulb. Thomas Edison discovered that filaments lasted longer in a vacuum. Today’s low energy bulbs still use vacuum technology.

High Throughput Diffusion Pumps

The Edwards HT and EO diffusion pumps offer the highest throughput (pressure multiplied by pumping speed) of any comparable sized pump, making them ideal for industrial processes that involve large quantities of gases. These diffusion pumps can be used on processes with high critical backing pressure and feature baffles to ensure backstreaming is minimized.
