Stationary Air Compressors for Sale

Stationary air compressors are fixed-installation systems designed for permanent placement in a shop, garage, or facility. They typicaslly deliver higher CFM and larger tank capacity than portable units, providing the sustained air supply that shop and industrial operations demand. CompressorPros carries stationary compressors from 3 to 200+ HP. All orders ship free.

What Are Stationary Air Compressors?

A stationary air compressor is a fixed-installation unit intended to stay in one location, connected to a permanent air distribution system or used as a dedicated shop compressor. Stationary compressors typically use larger tanks (60-240+ gallons), higher-HP motors, and heavier-duty pumps than their portable counterparts, delivering the sustained CFM and duty cycle that auto body shops, woodworking studios, manufacturing plants, and industrial facilities require. If your compressor serves a fixed work area and does not need to travel to the job, a stationary unit will deliver more air, more reliably, at a lower cost per CFM than a portable model.

Reciprocating (Piston) vs. Rotary Screw

Stationary compressors use two main pump technologies, and the right choice depends on your duty cycle and air demand.

Stationary Reciprocating (Piston) Compressors

Stationary piston compressors are the most common and most affordable option for shops that use air tools intermittently throughout the day. They are available from 3 to 15 HP with 60-120+ gallon tanks, delivering 12-50+ CFM. Two stage models are the standard for stationary shop use, reaching 175 PSI with greater efficiency than single stage designs. The BelAire 4916V 5 HP Two Stage 60 Gallon Air Compressor is a great lower volume stationary piston compressor on the site, and the Quincy 4153DS12HCA46 15 HP QT PRO 120 Gallon Horizontal Air Compressor represents a more industrial compressor of the reciprocating range.

Stationary Rotary Screw Compressors

Rotary screw compressors deliver 100% duty cycle, meaning they can run continuously without overheating or excessive wear. They are quieter, require less frequent maintenance, and scale to much higher HP than piston models. Stationary rotary screw units range from 3 to 200+ HP and serve shops and facilities that need sustained airflow throughout the workday. The Quincy QGS 5 TMD-1 5 HP Rotary Screw Air Compressor with Dryer is a popular stationary rotary screw, while the Elgi EG37-150 50 HP Base Mount Rotary Screw Air Compressor serves industrial-scale demand.

Tank Orientation

Stationary compressors are available in three mounting configurations, and the right one depends on your floor space and system layout.

Vertical Stationary Air Compressors

Vertical stationary air compressors stand the tank upright, occupying the smallest floor footprint of any stationary configuration. They are a strong choice for shops where floor space is limited but ceiling height is not a constraint. Vertical tanks are common in the 60-80 gallon range for 5-7.5 HP piston compressors. The C-Aire A075V080-1230 7.5 HP Two Stage 80 Gallon Air Compressor is available in a vertical tank configuration.

Horizontal Stationary Air Compressors

Horizontal stationary air compressors lay the tank on its side, providing a lower center of gravity and a more stable platform. Horizontal orientation is the standard for larger tanks (120-240 gallons), rotary screw tank mount systems, and industrial installations. Most compressors above 10 HP ship in horizontal configuration.

Base-Mount Air Compressors

Base-mount air compressors ship as a standalone compressor and motor without a built-in tank. The facility provides a separate air receiver sized to its specific demand. Base mount is the standard for rotary screw systems above 15 HP and for facilities with centralized tank and piping infrastructure.

Key Specifications

CFM (Cubic Feet per Minute): Stationary piston compressors deliver 12-50+ CFM; stationary rotary screw compressors deliver 15-350+ CFM. Add up the CFM requirements of all tools and processes running simultaneously and include a 25-30% buffer.
HP (Horsepower): Ranges from 3 HP for entry-level shop compressors to 200+ HP for industrial rotary screw systems.
Tank Capacity (Gallons): Vertical and horizontal piston units use 60-120 gallon tanks. Rotary screw tank mount systems use 60-132 gallon tanks. Larger facilities pair base-mount compressors with separate 120-240+ gallon receivers.
Max PSI (Pounds per Square Inch): Two stage piston models deliver up to 175 PSI. Rotary screw models typically deliver 100-150 PSI.
Voltage/Phase: 3-7.5 HP units are available in 230V single phase. Units 10 HP and above commonly require 208-460V three phase power. Confirm your electrical service before ordering.
Duty Cycle: Reciprocating compressors are typically rated at 50-70% duty cycle. Rotary screw compressors are rated at 100%. Match duty cycle to how many hours per day the compressor will run.

FAQ

What size stationary air compressor do I need for my shop? Start by listing every pneumatic tool you plan to run simultaneously and adding up their CFM requirements. For a single-bay auto shop running an impact wrench and die grinder, a 5 HP two stage compressor on a 60-80 gallon tank is a practical starting point. Multi-bay shops and continuous-use facilities should consider 7.5-15 HP piston or 5-15 HP rotary screw systems.

What is the most common mistake when buying a stationary compressor? Not planning for electrical requirements. Stationary compressors above 5 HP commonly need a 230V dedicated circuit, and units 10 HP and above typically require three phase power. Verify your panel's capacity and available circuits before purchasing.

Should I buy a piston or rotary screw stationary compressor? If you use air tools intermittently and want the lowest upfront cost, a two stage piston compressor is a practical choice. If you run air tools for most of the workday and value lower noise, and 100% duty cycle, a rotary screw is the better long-term investment.

Do stationary compressors need a separate air dryer? For spray painting, powder coating, and moisture-sensitive processes, yes. Some rotary screw models include an integrated dryer. Piston compressors require a separately purchased dryer if dry air is needed.

Can I install a stationary compressor in a garage? Yes. Vertical tank models fit well in garages with limited floor space. Ensure the location has adequate ventilation, a dedicated electrical circuit, and clearance around the compressor for airflow and maintenance access.

Does CompressorPros offer free shipping on stationary air compressors? Yes. All orders ship free, direct from the manufacturer, on every unit in this category.
