Staged Scroll Technology
Patented staged scroll technology from Air Squared allows for high vacuum capability in a compact and lightweight design - ideal for applications with challenging performance, size, and weight requirements.
Modern innovation drives technological progress into an ever-shrinking footprint, continuously challenging pneumatic solutions to deliver better performance in less space. Simultaneously reducing moving parts and increasing or maintaining performance, patented staged scroll technology from Air Squared is ideally suited for vacuum applications with challenging size and weight restrictions.
Staged scroll technology adds a second involute to the back of the orbiting scroll and a mating involute to the housing, packaging multiple vacuum stages (in series or parallel) in a single compact design. All stages operate using a common crankshaft, motor, and housing, substantially reducing the size, weight, and componentry. The unique configuration can be used to create compact two-stage, three-stage, or four-stage scroll designs.

Oil-Free Scroll Design
Orbiting scroll technology offers a quiet oil-free alternative to traditional technology like piston, diaphragm, and vain.
Using patented coatings and staged scroll technology, scroll vacuum pumps can achieve high vacuum without the need for a roughing pump.
Unique staged configurations allow scroll compressors and vacuum pumps to fit in small space envelope without sacrificing
Using patented staged scroll technology, vacuum pump solutions can be engineered incredibly lightweight.
Gases other than Air
With several patented sealed and semi-hermetic configurations, staged scroll vacuum pumps can be designed for compatibility with a wide-range of working fluids.
Staged Scroll Technology Explained
Staged scroll technology significantly reduces the size and weight of an oil-free scroll design. This is the best place to start for a basic understanding of the technology and how it can support your application.
Flow Rates 0 – 3,000 lpmv
Vacuum < 2 mTorr
Expansion Output 10 – 80 kWe
Staged scroll technology describes a patented configuration that allows multiple stages to be arranged in a single compact package to increase pressure or increase flow. All stages share a common crankshaft, motor, and housing. The unique configuration can be used for two-stage, three-stage, or four-stage scroll designs and can operate in series, parallel, or both.
In a two-stage design, an additional involute is added to the back of the orbiting scroll and a mating involute is added to the housing, allowing a single orbiting scroll to be used for two stages simultaneously.
Each stage can be optimized based on the required displacement and required vacuum, compression, or expansion.
Staged scroll technology allows all stages to share a common crankshaft, motor, and housing. By removing redundant components between stages from the design, the overall footprint of the design is substantially reduced without sacrificing performance. The reduced part count also improves reliability, reduces cost, and reduces weight.
