The new 7/53 HA portable compressor from Doosan has applications in a wide range of segments and can withstand tough conditions.

Doosan Portable Power has enhanced its small portable compressor range, which is aimed at a wide range of applications in plant hire, construction and general industry, including powering breakers and tools in road repair, demolition and refurbishment.

The latest addition to the range is the new 7/53 HA portable compressor, which replaces the previous 7/51 HA model.

“Doosan Portable Power offers one of the most comprehensive ranges of portable compressors for the Middle East and Africa market,” says a spokesman for the company. “It includes a strong selection of small Stage IIIA/Tier Three models, including the 7/20 and the high ambient 7/26E HA, 7/31E HA, 7/41 HA and 7/53 HA models, with free air deliveries from 2 to 5 cu m per minute (70-177 cfm) and a rated operating pressure of 7 bar (100 psi).”

“Like all Doosan compressors, they are built to withstand the rigours of everyday applications in the toughest conditions,” he adds.

In addition, he says, small portable compressors from Doosan can be equipped with a ‘bunded base’ option for environmental safety, providing a fully contained base to ensure that all operating fluids (fuel, oil and water) stay within the compressor.

The 7/26E HA, 7/31E HA, 7/41 HA and 7/53 HA models offer a number of important options, including an integral 6 kVA generator, which increases compressor flexibility by supplying electrical output in addition to compressed air. As a result, electric tools or other electrical equipment such as lights and fusion welding systems can be run in parallel with pneumatic equipment.

The new 7/53 HA has been redesigned by Doosan so that it remains in the Stage IIIA category, avoiding the need to transition to meet Stage IIIB regulations and ensuring it is ideal for use in the Middle East market. It supplies 5 cu m per minute (177 cfm) of compressed air and is powered by the four-cylinder mechanical turbo-charged Yanmar liquid-cooled 4TNV84T-BMDP engine producing 36 kW (49 hp) of power at 2,600 rpm.

Like all the other models in the small compressor range, the 7/53 HA can be supplied with a range of running gear options to meet local market requirements. The running gear can also be replaced with a permanent metal support, typically ordered when the compressor is to be truck-mounted.

The 7/53 HA comes in a reduced size, with a length of 3,389 mm in the fixed height, running gear version and a minimum/maximum height of 3,520/3,770 mm with adjustable height running gear. The model also has a width of 1,432 mm, a height of 1,301 mm and additional new features include integral forklift slots and increased fuel autonomy.

“The serviceability of all Doosan small compressors is excellent with easy access to all maintenance points,” the spokesman continues. “All areas have been carefully designed for ease of inspection, maintenance and repair. Service intervals for several components have been extended to increase uptime and reduce maintenance costs. The 7/53 HA incorporates a new spin-on separation element that further reduces service time.

“All Doosan small portable compressors have an intuitive, simple key-start sequence, ideal for construction and rental companies because of the reduced risk of machine abuse by untrained operators.”

The user-friendly control panel offers an open layout of instruments and warning indicators. A folding lift bail reduces the risk of theft by keeping the lifting eye within the compressor enclosure.
