The TANDEM version is a unit made up of two Skid compressors assembled on a single tank as the previous version, with a second compressor and it can work as stock or as support in case the need of air should be higher than the yield of the single compressor.
Particularly suitable for the most common uses requiring air without oil with variable consumption values or requiring a stock.

General's oil less riser mounted air compressors are fully automatic, and virtually maintenance free. OL Series riser mounted compressors are designed to be easily installed either vertically or horizontally to the riser. Units may be installed as air maintenance compressors. All units are UL 2125 Listed. Standard motors are single phase. Three Phase and 50 Hz units are available - consult factory.

‘Oil free’ single cylinder and bi-cylindrical piston air compressors, also available in silent version with cooler and dryer.
The dry-type (oil-free) OFP series is designed mainly for medical and dental use. This is possible since the compressor group is not lubricated and, on top of that, the generated compressed air is cooled and subsequently dried, in order to eliminate all condensate residue that is produced during the compression process; the air vessel inside surface is treated to avoid any possible contamination
Thanks to the oil free pump the compressor produce high-quality compressed air, without presence of oil residual. With the cooler and dryer version, the air becomes perfectly dry, and therefore eliminates problems with eventual condense.

DYNAMIC series
Power class: 65-370 kWOil-free compressed air at the best possible cost-benefit ratio! The DYNAMIC series offers an oil-free, two-stage turbocompressor series in the power output range of 65 to 370 kW with volumetric flow rates of between 9.7 and 65.5 m³/min and 9-bar final compressing pressure.
The DYNAMIC series is particularly suitable for applications in the medium to large industry sector, for example petrochemicals, refineries, the steel and automotive industries. In other words, wherever an even and extemely reliable compressed air supply is required; and particularly economical to boot!
Advantages:
100% oil-free compressed air
Clearly defined operating costs
Extremely low energy costs for plant operation
Very compact design with extremely high delivery quantity
User-friendly micro processor control
Minimum maintenance cost
Available as an open system or in a sound-insulated version

The compressors are designed as fully integrated, compact silenced packages with drive motor, coolers, moisture drains, reverse osmosis system and filtration along with a controller to ensure optimum efficiency and reliability. The Full Feature versions include the integration of environmentally friendly refrigerant dryers to ensure compliance with your air quality requirements and make the best use of your valuable floor space.
The Integrated frequency converter of the AQ VSD series varies the speed of the drive motor in order to exactly match the changes in your compressed air demand, thus using the minimum amount of energy and more than justifying the additional investment.
