Sauer’s modern reciprocating compressors are capable of compressing air and a variety of gases at pressures ranging from 20 to 500 barg, while also offering customized solutions for OEMs and global operators. Supported by an extensive worldwide network and complemented by engineering expertise, accessories, assembly, and service capabilities, Sauer delivers complete compressor system solutions, including turnkey installations. Through this partnership, All Marine Spares is excited to provide customers with access to Sauer’s trusted compressor technology and global support network.
3-stage air-cooled starting-air compressors
Unmatched reliability, operational efficiency, easy maintenance: these benefits have made Sauer’s Passat 3-stage air-cooled compressors best sellers for years. By combining 3-stage compression with air cooling, the Passat compressors enable low compression temperatures – and those three benefits.
3-stage air-cooled starting-air compressors
Exclusively developed for commercial shipping, our Levante 3-stage air-cooled compressors have quickly become the must-have solution for the maritime industry. A robust, compact design allows these low-maintenance compressors to fit easily into any engine room. A newly developed CubeCooler installed between motor and compressor has optimized the airflow, reduced the re-cooling temperatures by a third and thus boosted inter-cooling efficiency. Last but not least, the user-friendly human machine interface with an integrated gauge panel has made Levante compressors even easier to operate.

Basic benefits
Today the Sauer 3-stage air-cooled design is the leading starting air compressor in the world of shipping. Used by all major shipyards and shipowners as a standard – well known for its high quality and competiveness.
Less temperature due to lower stage pressure ratio!
In former times air-cooled compressors were limited to 80 m³/h due to the high compression temperatures (above 250 °C). With the development of the 3-stage air-cooled compressors more than 30 years ago, a new generation of compressors appeared in the market. The 3 stages are the reason for the lower temperatures (less than 170 °C) and make satisfactory cooling by air possible.
Due to the laws of physics air is heated during compression. The final compression temperature depends on the compression-ratio in each stage. By dividing up the total compression-ratio into 3 stages, lower compression temperatures in the cylinders and valves can be achieved compared to 2-stage water-cooled compressors.
Temperature rise of air during compression
Temperatures rise so far during compression. Temperatures calculated based on the laws of physics and technical regulations. Above mentioned temperatures occur in the cylinders/valves and cannot be compared with temperatures displayed on compressors by standard thermometers.
Due to the lower compression temperatures the thermal cracking of the lubricating oil will not be reached and consequently the compressor valves will not be soiled by oil coke. Thus Sauer Compressors can guarantee maintenance intervals up to 4,000 hours for the valves which reduce the maintenance costs compared to 2-stage water-cooled compressors. The reduced compression temperatures allow the use of standard mineral oil SAE 30 as it is used e.g. in 2- and 4-stroke diesel engines. The use of expensive synthetic oil is not required for proper performance.
Sauer 3-stage air-cooled compressors – for lowest operation costs of your ship
■ Extended life time of the valves (up to 4,000 hours) with less maintenance costs due to lowest compression temperatures ■ Reduced crew costs due to easy maintenance ■ Designed for use with standard mineral oil SAE30 ■ No corrosion or water leakages ■ Operation of air-cooled compressors independent from central CW system, as emergency compressor
By abolishing the cooling water circuit with its flanges, packings, fittings and cooling water pumps, a higher reliability and an easier control and supervision of the compressors is achieved.
The simple way of cooling is also the reason for more and more shipyards to prefer air-cooled compressors. In addition to the fact that an auxiliary with less interfaces is installed, the weight and space is smaller thus enabling lighter and less expensive foundations. In total, cost savings of up to 7,500 USD per ship are possible during installation. The ventilation of the engine room has not to be increased, the compressors just need to be taken into consideration in the arrangement of the ventilation.
Sauer 3-stage air-cooled compressors – the most competitive option also for shipyard and shipowner.
■ Available from 60 up to 460 m³/h capacity ■ Final pressure up to 45 barg ■ More than 30,000 units sold since 1970 ■ Suitable for continuous running 24/7 ■ Separator mounted after each stage ■ Reliable and safe operation up to 60 °C
2-stage air-cooled starting-air compressors up to 80 m³/h
Our Mistral 2-stage air-cooled starting-air compressors are renowned for their robust dependability, even in the most challenging ambient conditions – temperatures of up to 60° C. are no problem. The low installation and maintenance costs of Mistral compressors add to their appeal in everyday shipping applications.
■ Low installation cost due to absence of cooling water circuit ■ Light-weight and less space required for installation ■ Reliable and safe to operate, even at ambient temperatures up to 60 °C ■ Suitable for even the most difficult ambient conditions
2-stage water-cooled starting-air compressors up to 440 m³/h
For applications where air-cooled compressors are unsuitable our Typhoon 2-stage water-cooled starting-air compressors offer an extremely reliable and efficient alternative. With decades of experience in this field we have the know-how to regularly advance the technology behind these dependable machines.
Control- and working-air compressors
Whether you need control air or working air, we can supply you with exactly the screw-type or piston-type compressor to suit your specific shipping needs. For requirements under 100 m³/h we recommend piston-type compressors; for requirements over 300 m³/h screw-type compressors. For the 100–300 m³/h range we also recommend screw-type compressors, providing the annual operation time exceeds 4,000 hours.
Sauer SC screw compressors
Our screw compressors reflect our in-depth understanding of commercial shipping’s requirements and decades of experience in this field, they offer you much more than normal industry compressors. Sauer screw compressors are designed to ensure trouble-free operation anywhere on the Seven Seas. They are available with fixed speed or optionally with variable-frequency drive (VFD).
Piston-type compressors
In line with your specific needs we can also supply reciprocating piston-type compressors based on our renowned range of starting-air compressors. These piston-type compressors are more suitable for shorter operation intervals as they are start-stop controlled, which reduces their energy consumption. Our piston compressors offer the important benefits of standardised parts and a similar design to our air-cooled starting-air compressors. This offers you another important advantage.
SCR system for NOx reduction
Exhaust gas purification is crucial. To supply state-of-the-art SCR systems for the reduction of nitrogen oxides with compressed air, the Sauer SC85 and SC99 screw compressors deliver a volume flow of up to 700 m³/h with a maximum power of 99 kW.
Sauer Marine Logic Control (MLC)
■ State-of-the-art electronic compressors controls ■ Robust design for marine ambient conditions ■ In compliance with all classification requirements

Sauer RCC
Besides a robust design and compliance with classification requirements, the RCC offers an optional Sauer EcoBox for lead-lag control and a selection of compressor starting sequences.
Although Sauer compressors are renowned for their dependability and low maintenance requirements, at some stage in a Sauer compressor’s service life parts will need replacing. And the last thing you then want is an undue wait for a spare part or service technician to arrive. If you choose one of our Sauer Service packages, you can be sure of not just outstanding support but also of fast assistance in getting your system up and running again.
