Video: New small stage V compressors from Doosan
Doosan Portable Power has launched a new range of small portable compressors for the European market, offering four new models with free air deliveries from 2.5 to 5.0 m³/min (90-180 cfm) and designed with a focus on simplicity, durability, reliability and transportability.
About 70% of the EU portable compressor market is represented by machines between 2.0 and 5.0 m3/min. The main European markets are the UK, GAS (Germany, Austria and Switzerland), France and Benelux (Belgium, Netherlands and Luxembourg), which together represent more than 70% of the industry covering many sectors including rental, construction, utilities, demolition and general industry. Doosan Portable Power has very strong sales in this region and is one of the top three players in the market.
In the new small compressors, the first number in the model name indicates the pressure in bar, the second number represents nominal air flow in cubic metres per minute, while the number 5 at the end indicates a Stage V compliant engine. There are three models operating at 7 bar nominal pressure - the new Stage V Yanmar-powered 7/25, 7/45 and 7/55 with outputs of 2.5, 4.0 and 5.0 m³/min (90, 140 and 180 cfm), respectively. The small compressor range is completed by the new 14/35 higher pressure model providing 3.0 m³/min (105 cfm) of compressed air at 13.8 bar.
Jan Moravec, general manager, Doosan Portable Power for Europe, the Middle East and Africa, said: “The design complexity required for the implementation of the latest Stage V engines led us to completely rethink the design of the small compressor range, while maintaining the well accepted, superior durability of our products, improving the serviceability and fulfilling all possible transportability requirements, at the same time as expanding our focus on environmentally friendlier solutions.
“As a result, like in our larger compressor ranges, a leak-free bunded base is now fully integrated into the bottom frame of the new small compressors and includes the central drains for all fluids. For the Stage V units with electronic control, we have also introduced the option of the ECOmizer feature, which reduces emissions, noise and fuel consumption.”
Machines equipped with the ECOmizer option will automatically recognise the working phase and will act on pressure and engine speed without the intervention of the operator to optimize the fuel consumption and to reduce noise and emissions. As soon as the operator activates a pneumatic tool being powered by the compressor, the machine will automatically recognize the demand of flow and pressure, providing the maximum performance immediately. For example, in a working cycle with 50% full load and 50% idle speed, the ECOmizer provides 60% savings in fuel.
Michele Corsi, product manager, Doosan Portable Power, added: “The most immediate, noticeable change in the 7/25, 7/45, 7/55 and 14/35 Stage V units is the new dynamic and modern appearance, thanks to an updated design, bringing a fresh new look. The success of the previous Tough Top (polymer) canopies has led Doosan Portable Power to offer this solution as standard.
“The new easy-to-open canopy creates a fantastic line with the newly designed polymer mudguards and bumpers. The newly integrated LED lights are also offered as standard for all the machines. And of course, the long-standing metal canopy versions will still be available to customers as an option.”
Other improvements in the new small compressor range include the updated control panel, which has been repositioned for more ergonomic access and is now protected by a lockable cover. A simple mechanical manometer reports the pressure, and on models with electronically controlled engines, there is an additional switch to force DPF regeneration. For machines with the generator option, there is also an additional 3-position switch and voltmeter.
