Orbtial Series Scroll Compressor Technology Overview
The namesake of traditional scroll-type designs are the two primary components, an orbiting scroll, and a fixed scroll. The orbiting scroll is coupled to a crankshaft that orbits the scroll eccentrically, following a fixed path with respect to the mating (fixed) scroll, creating a series of crescent-shaped pockets between the two scrolls. In the case of a scroll compressor, the working fluid moves from the periphery (inlet) towards the center (discharge) through increasingly smaller pockets, generating compression.
The operating principles of oil-free scroll compressors are similar to those of lubricated scroll compressors commonly used throughout the refrigeration industry. The primary difference is oil-free scroll compressors use three idler shafts to maintain a close running clearance between the fixed and orbiting scroll instead of an Oldham ring.
Orbital Series Scroll Compressor Advantages
- Orbital Series scroll compressors are 100% oil-free.
- Orbital Series scroll compressors are considerably more quiet and smooth-running than competing technology, such as reciprocating and vane. The geometry of the scroll delivers continuous flow and eliminates the need for valves, resulting in significantly less port pulsation and associated noise. The unique orbital motion is dynamically balanced, minimizing vibration and reducing rubbing velocity far below piston rings or vanes. Combined with the absence of several moving parts, Orbital Series scroll compressors offer a vast improvement over traditional technology, with quiet, smooth, pulsation-free operation.
- Orbital Series scroll compressors eliminate re-expansion losses – a problem found in reciprocating machines with every piston stroke – improving volumetric efficiency. Additionally, throttling losses are nonexistent with the valveless design.
- Orbital Series scroll compressors offer a durable and robust solution, with 70% fewer moving parts than reciprocating technology and only two primary moving parts.

Orbital Series Scroll Compressor FAQs
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.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.

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