One compressor, multiple applications: Properly sizing compressed air systems for gas stations and car washes
At a gas station or car wash, a single compressor often supplies several areas simultaneously: tire inflators at the pump islands, pneumatic systems for the car wash, self-service foam lances, and tools used in the workshop or for vehicle detailing. If this system fails or the air pressure drops, multiple revenue-generating operations can come to a standstill.
The right system depends primarily on air demand, pressure requirements, available floor space, and air quality standards. In this article, we compare two KAESER product lines—the EUROCOMP piston compressor and the SXC screw compressor station—which we offer for these types of applications as an authorized KAESER partner in Baden-Württemberg.
Compressed air requirements for various applications
Different equipment at a site has different requirements. Determining which area is the most demanding is the key to selecting the right system.
Application | Typical Users | Critical Factor |
|---|---|---|
Tire service | Tire inflators, tire changing machines, initial inflation | Constant pressure, availability during customer interaction |
Car Wash, Self-service Wash Bay | Solenoid and pneumatic valves, foam lances | Dry compressed air (to prevent condensate in valves) |
Workshop | Impac wrenches, vehicle lifts | Air volume during peak loads |
Vehicle detailing | Interior cleaning guns | Air volume, potentially filtration at the point of use |
This article intentionally avoids providing generalized values for the air volumes and operating pressures required by individual pieces of equipment. These figures vary depending on the manufacturer and the number of workstations, and should be determined through a formal assessment of specific requirements.
KAESER EUROCOMP: Piston compressor for workshops and tire service centers
The EUROCOMP series consists of stationary, oil-lubricated piston compressors designed for daily workshop use. They operate at 10 or 15 bar and are available in three different installation configurations.
Configuration | Application |
|---|---|
Horizontal air receiver | Standard version, where sufficient floor space is available |
Vertical air receiver | For confined spaces (requires a maximum footprint of 0.85 m²) |
Compressor unit without receiver | For replacing an older unit on an existing air receiver |
Design
- The compressor block and motor are directly coupled, eliminating the need for belts.
- The valves feature lift-limiting designs and stainless-steel reeds. This improves heat dissipation and helps prevent the buildup of carbon deposits from oil.
- Aluminum cylinder heads and additional cooling pipes keep both air and oil temperatures low.
- The compressor, motor, and receiver are isolated from one another using vibration-dampening rubber-metal mounts.
- Motor: 4-pole, 1,500 rpm, 400 V/50 Hz, IP 54 protection rating
Options and Accessories
- Sound-insulating enclosure (factory-fitted or retrofittable)
- ECO-DRAIN electronic condensate drain for the air receiver
- Oil level monitoring with automatic shut-off in the event of low oil
- Star-delta starter (required for motor outputs of 5.5 kW and above)
- Downstream refrigerated dryer (for applications requiring dry air)
Air receivers with a capacity of up to 350 litres feature an internal coating. The unit’s air receivers are hot-dip galvanised and designed in accordance with the AD 2000 standard.
EUROCOMP is highly versatile: ideal for workshops, tyre service centres, and car wash system components.

KAESER SXC: A complete compressed air station in just 0.62 m²
The SXC combines a rotary screw compressor, a refrigerated dryer, and a compressed air receiver under a sound-insulated enclosure, occupying a footprint of only 0.62 m². This makes it an ideal solution for technical rooms at service stations and car washes where there is no space for three separate components.
Parameter | Value |
|---|---|
Pressure | up to 15 bar |
Flow rate | up to 0.80 m³/min |
Motor power | up to 5.5 kW, IE3 energy-saving motor |
Compressed air receiver | 215 l, internally coated |
Foot print | 0.62 m² |
Refrigerated dryer refrigerant | R-513A, GWP 629 |
Why is this relevant for a car wash system?
The integrated refrigerated dryer removes moisture from the compressed air before it enters the distribution network. This protects the solenoid and pneumatic valves in the car wash system from condensate and corrosion. The condensate is electronically drained from the reservoir.
Technical details
- Screw compressor block featuring the SIGMA PROFILE; according to KAESER, this requires approximately 10 to 20% less energy than conventional rotor profiles while delivering the same air volume.
- V-ribbed belt with automatic tensioning—no manual re-tensioning required.
- SIGMA CONTROL system with a plain-text display, Ethernet interface, and web server.
- Enclosure made of double-walled polyethylene; once removed, all maintenance points are easily accessible.
Installation
The unit requires a power connection and a link to the compressed air network. There is no need for a separate dryer or the associated piping.
EUROCOMP or SXC: Comparison and selection guide
Feature | EUROCOMP | SXC |
|---|---|---|
Compression principle | Piston, oil-lubricated | Screw, fluid-cooled |
Pressure | 10 or 15 bar | up to 15 bar |
Flow rate |
112 - 1.050 l/min | up to 0.80 m³/min |
Footprint | From 0.85 m² (upright) | 0.62 m² |
Dryer | External accessory | integrated |
Compressed air receiver | horizontal, upright, or existing | integrated, 215 l |
Sound insulation | Enclosure optional | Enclosure standard |
Control system | KAESER control monitoring module with star-delta starter (accessory) | SIGMA CONTROL |
EUROCOMP: The ideal system when compressed air is primarily required for workshops or tire service, when an existing air receiver is to be reused, or when an older unit needs to be replaced on a one-to-one basis.
SXC: An ideal system if you also need to supply a wash bay, require dry air, and have limited space in your technical room.
