Profile: Edwards is a supplier of integrated solutions for the manufacture of semiconductors, flat panel displays, LEDs and solar cells. Our products include small wet or dry pumps, EXT trbo pumps, STP turbo pumps, small & large diffusion pumps, vacuum valves, vacuum fittings and semiconductor pumps. Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. Our vapour handling is enabled by an adjustable gas ballast and this allows the range of pumps to satisfy many applications that were previously off limits to other scroll pumps. EXT turbomolecular and compound molecular pumps provide a reliable, hydrocarbon-free high and ultra high vacuum. Our EXT design provides oil and vibration free operation with minimal maintenance on high critical foreline pressure processes.
