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.

Scroll Vacuum Pump FAQs

Most Air Squared products do not have a CE conformity marking.

Our products are primarily designed for OEMs and not intended for end users. As most OEM systems already require CE marking, conformity specific to an Air Squared product is generally not required. OEM customers that require conformity specific to an Air Squared product should contact their Sales Representative.

Monitoring speed is an important aspect of operating a scroll compressor or vacuum pump, as operation over the specified maximum speed can result in premature or catastrophic failure.

For scroll compressors and vacuum pumps that have a brushless DC motor, speed can be measured by connecting a digital tachometer between a hall sensor and ground. The tachometer must be programmed to the correct number of pulses per revolution, which can be determined by dividing the numbers of motor poles by 2. For example, an 8-pole motor will have 4 pulses per revolution.

Alternatively, an oscilloscope can also be used to measure the frequency of the hall sensors. Divide the measured frequency by the number of pulses per revolution and multiply by 60 to determine the RPM.

For scroll compressors and vacuum pumps that have an AC motor, speed can be measured by multiplying the frequency of the variable frequency drive (VFD) by 60 to determine the RPM.

Most scroll vacuum pumps have a discharge port centered on the face of the unit, with the inlet port positioned near the periphery.

Air Squared does not provide operation manuals for most products.

Given the specialized nature of our scroll products, Air Squared works directly with OEM customers to install, operate, test, evaluate, and service products. Customers who require an operation manual should contact their Sales Representative.

If you do not have a Sales Representative, start with our Application Assistant or contact Sales directly.
