High-Quality Cooling

A separate oil and air cooler in the Largo 31-110 range allows for high-quality cooling. Thanks to this you can expect a longer lifetime of the coolers.

Easy to Clean

With gliding rails and easy access, the coolers are easy to clean, and rails are easy and safe to remove.

Quality Components

An internal water separator combined with an automatic drain reduces up to 90% of the condensate in the compressed air. There is no air loss during the removal thanks to the automatic drain. This is standard in the Largo 31-37-45.

High-Quality Largo 31-110 Screw Air Compressor

The Largo 31-110 screw air compressor range provides high-quality compressed air suitable for a wide range of industrial applications. The Largo 31-110 is the result of continuous investment in product development. The compressors have been built around innovative features which make this screw air compressor range stand out.

Gearbox Driven Transmission

The Largo 31-110 screw air compressor range uses a gearbox driven transmission. The gearbox technology saves up to 3% efficiency compared to belt driven technology. With the gearbox technology, there is no long-term loss of energy efficiency. For better energy efficiency, the Largo 31-110 screw air compressors use IP55, IE2 motors.

Innovative Design

The Largo 31-110 has been designed to withstand the harshest condition and ambient temperature up to 46°C. The innovative design of these screw air compressors results in a smaller footprint. The smaller footprint allows you to place the compressor against a wall. The noise of the screw compressor is reduced thanks to fitted insulation foam.

Better Energy Efficiency

There is a lower pressure drop in the Largo 31-110 with the removal of valves downstream air end. A lower pressure drop creates better energy efficiency. The repositioned outlet grating also causes less pressure drop and lower power consumption of cooling fan for better energy efficiency.

Radial Fan

A radial fan (or turbine) is used in the Largo 31-110 screw air compressor range instead of an axial fan. The radial fan is located above the main motor and separated from the cooler. 

The benefits of the radial fan are:
Superior energy efficiency
Better cooling
Low rotation speed
Uniform diffusion of the air
100% use of the cooler
Better efficiency
Reduced noise levels
Better cooling
Lower operation temperature
Lower energy consumption
Expanded lifetime of the machine

High Inlet Filtration Quality

There is guaranteed high inlet filtration quality in the Largo 31-110 screw air compressors thanks to the encapsulated air filter. This filter preserves the screw air compressor against dust. A pleated 2-micron media allows for a larger filtration surface area. 

Benefits include:
Expanded oil lifetime
Expanded filters lifetime
Rapid access for maintenance
No tooling required
Maintenance cost reduction
Low noise levels thanks to design and position of filter

Intelligent Control

The Airlogic full colour 4.3-inch HD touch display controller offers you intelligent control of the Largo 31-110 screw air compressor range. You will get full insight into your compressed air network and helps optimise and save energy. 

Control and monitoring features:
Intelligent unload cycle control
Precise pressure control
Warning indicators
Graphical indication service plan
Bult-in online monitoring
Online visualisation of running conditions
Compressor automatically adapts to demand changes

Connectivity is the Future

The Largo 31-110 screw air compressor range comes prepped with ICONS connectivity. 

Benefit from the advantages of ICONS:
Remote monitoring
On-time maintenance which optimises cost and ensures a longer machine life
Potential problems are recognised before they can pose a threat to the stability of your production

Energy Recovery Option

A major focus of compressed air installation should be reducing the energy consumption of your compressor. The energy recovery option can help optimise your energy consumption. Excess heat is captured with the energy recovery option and channelled into other applications. This will result in saving energy and cutting costs.

Integrated Air Dryer Option

The Largo 31-75 industrial screw compressors are available with an integrated dryer option. 

This option offers significant advantages compared to a stand-alone dryer including:
Condensation removal at source minimising pipework corrosion
Reduced footprint
Intelligent dryer control
Higher operating temperatures
Single service visits, reducing maintenance costs
No installation costs

Installations with Multiple Compressors

For installations with multiple air compressors, the EC0ntrol6 or the integrated compressor control (with a license) provides a simple solution. The central control reduces system pressure and energy consumption in installations of up to four or six compressors. 

Control features include:
Single pressire measurement point
Minimised pressure band
Stable system pressure
Equalisation of running hours
Multiple IVR speed control
Clear and visual graphical display
Online monitoring and controlling possible
