A diesel-powered compressor is a mobile, high-performance compressed air system in which a diesel engine directly drives the compressor, rather than an electric motor. As a result, the machine is completely independent of the power grid and can be used immediately at any location, even where there is no power connection.
Our rental fleet covers a wide range of power ratings, from compact units starting at 7.5 kW to heavy-duty, high-capacity machines for the most demanding construction and industrial applications. This way, you’ll never rent more capacity than you need, and you can easily scale up as your project grows.
This type of compressor is ideal for construction sites, road construction, industrial sites, and temporary setups with a temporary or fluctuating demand for compressed air.
From compact units to heavy-duty industrial systems: below is an overview of the available power classes in our rental fleet.
| Power Class | Engine power | Operating pressure | Typical Applications |
|---|---|---|---|
| Compact | 7.5 – 11 kW | 5 – 13 bar | Small construction sites, hand tools, temporary projects |
| Light | 15–22 kW | 5–13 bar | Medium-sized construction projects, multiple tool connections |
| Medium | 23–37 kW | 5–13 bar | Road construction, longer compressed air lines, broader applications |
| Medium-heavy | 45–75 kW | 5–13 bar | Larger construction sites, sandblasting, continuous use |
| Heavy | 90–160 kW | 5–13 bar | Industrial sites, large-scale projects, multiple users simultaneously |
| Extra Heavy | 160–355 kW | 5 – 14 bar | Large-scale industrial applications, high and continuous air demand |
Capacity and pressure are approximate and are customized for each project. Please contact us for a compressor that precisely meets your air requirements.
Completely independent of the power grid. Because the diesel engine drives the compressor directly, no electrical connection or generator is needed. This makes the machine ideal for remote locations or sites in the early stages of construction.
Quick to deploy at any location. Mounted on a trailer or skid, the compressor is easy to transport and can be up and running within an hour, without the need to connect to the power grid.
Wide Power Range From compact 7.5 kW units to heavy-duty systems for large-scale applications—there’s always a machine that perfectly meets your air requirements.
Robust and designed for harsh outdoor conditions. Thanks to its weather-resistant design, sound insulation, and robust construction, the machine continues to perform reliably on construction sites and industrial sites, even during prolonged use.
Versatile For use with pneumatic tools, jackhammers, sandblasting, road construction, temporary industrial applications, and events at locations without permanent facilities.
No investment, but peace of mind. No high CapEx: you rent exactly the capacity you need, for exactly as long as you need it. Maintenance and service are included as standard.
Fuel Consumption and Logistics The tank must be refilled periodically; for long-term or continuous use, fuel delivery must be scheduled.
Exhaust Emissions: When used in enclosed spaces, adequate ventilation or exhaust gas removal is required.
Regular engine maintenance is necessary: engine oil, fuel and air filters, and the cooling system; if maintenance is neglected, reliability and service life will decrease.
Noise Level: Depending on power and load, the noise level can be significant; in noise-sensitive locations, additional soundproofing may be desirable.
Less suitable for permanent, fixed installations. For long-term, fixed compressed air needs at a location with a power connection, an electric compressor is generally the more cost-effective choice.
| Situation | Why rent? |
|---|---|
| Construction sites or areas without a power connection | Compressed air is immediately available, even at locations where the utility grid has not yet been installed. |
| Road Construction and Temporary Work Sites | The machine is portable and can be moved along with the route or the phasing of the project. |
| Backup Power in the Event of a Power Outage or Failure | Your compressed air supply will continue to operate even if the mains power fails. |
| Short-term or seasonal projects | Rental period is limited, location may vary, and no investment in your own equipment is required. |
| Cost Control and Cash Flow Management | No high CapEx; fuel advice, maintenance, and servicing are often included in the lease package. |
