Oil Lub Piston LER LTR & Oil-Free Piston LFR
Reliable piston performance
Space and reliability are key when it comes to air supply in mining equipment and service vehicles. Our range of hydraulic driven compressors is made specifically for these applications. You can chose your hydraulic piston solution from our oil injected LE range, our oil-free LF or the LT high pressure variants up to 30 bar.
With a proven reliability in the field of thousands of compressors, we deliver compressors that can be trusted in a cost effective solution. It comes in a tiny package that can be adapted with options like vibration dampers, pressure switches or heavier duty air filtration for the toughest environments.
Available from 140 to 1100 l/min (5 to 39 cfm) free air delivery.

Description
Features and benefits
Thanks to our direct drive concept, our compressors offer compact packages much smaller than belt driven equivalent, while at the same time removing the need for complicated belt replacement. This does however do not compromise the ease of maintenance as all the components needing service are conveniently placed in one location. Using corrosion resistant materials like stainless steel and aluminum, you can rest assured that the compressor will give you years of trouble-free usage.
Our hydraulic driven piston compressors come also equipped with load / unload valves to adapt air production independently from the oil supply to the motor. The capacity of the motor itself can be selected from a wide range to adapt the compressor oil flow and pressure to the size of your oil pump.
Qualities in the details
- Optimized fan design for efficient cooling and optimal compressor performance.
- Railway qualified vibration dampers for a minimum transfer of vibrations from and to the compressor package.
- High performance finned tube inter- and after-cooler.
- Load/unload valve with integrated blow- off function and non-return valve for low starting torque and easy control.
- Top quality direct drive aluminum compressor block in V-arrangement, for a compact and light-weight installation, high performance and extended lifetime even in the harshest ambient conditions.
- High efficiency industrial air intake filter for trouble-free operation.
- High efficiency hydraulic motor with superior performance and low noise levels, working even at high hydraulic operating pressures.
- Hydraulic connections according to international standards
Select features to suit your application needs
There are multiple options and variants available to choose from to ensure you have the most suitable equipment for your application. Choose from the high-pressure or oil-free compressor variants, and consider the various options such as the heavy-duty inlet filter, railway-qualified vibration dampers, protection canopy and motors.
Options
- Heavy duty inlet filter: For efficient operation in dusty environments and longer maintenance intervals.
- Railway-qualified vibration dampers: For a minimum transfer of vibrations from and to the compressor and motor.
- Protection canopy: Protecting the compressor from external particles and to place the compressor outside.
- Different selection of hydraulic motors: For an optimal balance between the performance of the compressor and the available hydraulic oil flow and pressure.
- Electric motor: High efficiency, totally enclosed fan-cooled (TEFC), IP 55, class F direct coupled railway-approved electric motor with greased-for-life bearings.
Variants
High-pressure compressor variant
- Two-stage up to 30 bar.
- Equipped with intercooler for improved efficiency.
Oil-free compressor variant
- No oil in the compressed air.
- Environmentally friendly oil-free piston.
- Less maintenance.
