The novelty of the all-metal scroll pump lies in the elimination of polymer-based tip seals that are common to all oil-free scroll vacuum pumps. With the removal of tip seals in the hermetically-sealed pump, the working fluid is only in contact with precision-machined stainless steel scrolls and a nickel-plated bellows, allowing the unit to support even the most demanding applications. Removal of the tip seals does not come at the expense of performance, as the unit is capable of vacuum below 5 mTorr without a backing pump.
While the all-metal scroll pump can also function as a compressor, Air Squared will first target vacuum
applications. The pump has relevance in several areas where traditional vacuum pumps are not suitable.
Selection of only corrosion-resistant alloys and metals throughout the pump design, make the pump compatible
with highly corrosive or high-temperature gases. The pump can also be used in applications that require zero
contamination and leakage, such as processing radioactive tritium.
Air Squared is the industry leader in oil-free scroll design and manufacturing. By introducing a simple design
with fewer moving parts, scroll technology has established itself as a highly efficient, very reliable, cost-effective alternative. Through a growing line of compressors, vacuum pumps, and expanders, Air Squared makes the many advantages of oil-free scroll technology available to OEMs worldwide.
