What Are Scroll Air Compressors?

A scroll air compressor uses two spiral-shaped elements, one stationary and one orbiting, to trap and compress air in progressively smaller pockets. Because the spirals never make metal-to-metal contact, no lubricating oil is needed in the compression chamber, and the resulting air stream is completely oil-free. Scroll compressors are a standard choice for hospitals, dental offices, pharmaceutical production, food and beverage plants, and electronics manufacturing, where even trace oil contamination can compromise patient safety, product quality, or process integrity.

Base Mount vs. Tank Mount

The most fundamental configuration decision for a scroll compressor is whether you need a base mount or tank mount system.

Base Mount Scroll Compressors

Base mount units ship as a standalone compressor and motor assembly without a built-in air receiver tank. The facility pairs the compressor with an appropriately sized remote tank and piping system. This configuration is standard for larger installations and allows flexibility in tank sizing, placement, and system layout. Most scroll compressors from 10 HP and above are available in base mount form. The Amico AE-SCR-20-463-FS 20 HP Enclosed Oil Free Scroll Air Compressor is a representative mid-capacity base mount system for facility-level clean air demand.

Tank Mount Scroll Compressors

Tank mount configurations integrate the scroll compressor, motor, and air receiver into a single package, simplifying installation and reducing floor space requirements. Some models also include an integrated refrigerated air dryer. Tank mount scroll compressors are common in the 5-10 HP range and are well-suited to dental practices, small laboratories, and standalone clean-air stations. The FS Curtis FES04A6U3QXXX 5 HP Oil Free Scroll Air Compressor Tank Mount with Dryer is an all-in-one example that combines compression, storage, and moisture removal.

Types of Scroll Air Compressors

Single-Module Scroll Compressors

These units use a single scroll compression element and typically deliver 15-40 CFM. They serve single-operatory dental offices, small labs, and light manufacturing applications that need clean, quiet air from a compact footprint. The Amico AE-SCR-05L-463-FS 5 HP Enclosed Oil Free Scroll Air Compressor is an entry point in this range.

Multi-Module Scroll Compressors

Higher-capacity scroll systems pair multiple scroll elements in a single enclosure, operating in tandem. These are special order, but we can quote these as needed.

Key Specifications

CFM (Cubic Feet per Minute): Total air volume at rated pressure. Single-module units deliver roughly 15-40 CFM; multi-module systems scale to 150+ CFM. Match CFM to the combined demand of all connected tools, instruments, or processes.
HP (Horsepower): Ranges from 5 HP for single-module systems to 40 HP for multi-module configurations. Because scroll compressors are inherently efficient, they often deliver comparable CFM to larger piston units at a lower noise penalty.
Max PSI (Pounds per Square Inch): Most scroll compressors deliver 100-150 PSI. Dental and medical applications typically operate at 80-100 PSI; industrial applications may require the full 150 PSI range.
Voltage/Phase: 5 HP models are available in 230V single phase for smaller facilities. Units from 7.5 HP and above generally require 230V or 460V three phase power.
Noise Level (dBA): One of the key advantages of scroll technology. Enclosed scroll compressors typically operate between 55 and 68 dBA, significantly quieter than comparable piston or rotary screw units, making them suitable for installation near patient care areas and work spaces.

FAQ

How does a scroll compressor differ from a piston or rotary screw? A scroll compressor uses two interlocking spirals instead of pistons or rotating screws. The spiral design produces no metal-to-metal contact, which means no oil is needed and noise levels are significantly lower. Scroll compressors are inherently oil-free, while piston and rotary screw units require oil-free-specific engineering to achieve the same air purity.

What is the most common mistake when buying a scroll air compressor? Not accounting for future expansion. Scroll compressors in medical and dental settings often need to serve additional chairs or instruments as a practice grows. Selecting a unit with some CFM headroom, or choosing a multi-module system that can be expanded, prevents the need for a full replacement later.

Are scroll compressors suitable for continuous-duty operation? Yes. Scroll compressors are rated for continuous duty (100% duty cycle) and are designed to run throughout the workday without overheating. Multi-module systems stagger the load across scroll elements, further extending component life.

How often does a scroll compressor need maintenance? Scroll compressors have fewer wearing parts than piston models, so maintenance intervals are typically longer. Most manufacturers recommend air filter replacement every 1,000-2,000 hours and periodic inspection of the scroll elements. There is no oil to change, which simplifies routine service.

Do I need an air dryer with a scroll compressor? For most medical, dental, and food-grade applications, yes. While the air is oil-free, compressed air still carries moisture. A refrigerated or desiccant dryer removes that moisture to meet air quality standards. Some tank mount models include an integrated dryer.
