Xas98kd 36kw 7bar Mobile Diesel Screw Air Compressor

XAS 98 Compact Diesel Portable Air Compressor

The Atlas Copco XAS 98 Air Compressor is a compact, diesel-powered portable compressor designed for construction, maintenance, and general pneumatic applications. Its oil-injected screw compression system delivers a continuous supply of compressed air, while the integrated diesel engine allows operation at sites without a fixed electrical supply.

Description

XAS 98 Portable Air Compressor

The Atlas Copco XAS 98 represents the pinnacle of high-output, compact mobile air supply. By packing a substantial 5.4 m³/min (190 CFM) flow rate into a highly maneuverable, sub-750kg chassis, it bridges the gap between small utility compressors and large towable rigs. Powered by a heavy-duty, liquid-cooled Kubota or Yanmar diesel engine (depending on regional emission configurations), this 7-bar workhorse is built for rapid deployment in urban street construction, heavy demolition, trenchless pipe rehabilitation, and high-intensity sandblasting.

Features That Matter on Site

Consistent Air Supply

The XAS 98 uses screw compression technology to provide compressed air for compatible pneumatic tools. Its rated airflow makes it a candidate for jobs where several tools or sustained air demand must be considered during equipment selection.

Independent Diesel Operation

The integrated diesel engine enables the compressor to operate independently of mains electricity. This is useful for contractors and maintenance teams working at outdoor or temporary locations.

Practical Transport and Setup

As part of Atlas Copco’s small mobile compressor range, the XAS 98 is designed for portable use. Confirm the actual operating weight, dimensions, and towing configuration of the specific unit when planning transport.

Serviceable Components

Routine inspection of filters, lubricants, cooling components, hoses, and connections helps maintain performance. Using the correct maintenance parts for the model and serial number also reduces the risk of compatibility issues.

Target Applications

• Multi-Tool Demolition: Concurrently driving up to 3 or 4 medium jackhammers, chipping guns, or pneumatic clay diggers.
• Heavy Utility Sandblasting: Providing steady, continuous air pressure for medium-scale building restoration and shipyard rust scaling.
• Pipe Bursting & Relining: Supplying high-volume pneumatic thrust for underground trenchless pipe rehabilitation.
• Ground Mole Drilling: Powering underground pneumatic piercing tools for laying utility cables under roads.

Maintenance and Spare Parts

To help keep the XAS 98 operating reliably:

Follow the maintenance intervals in the applicable instruction manual.
Inspect and replace engine and compressor air filters as required.
Check compressor lubricant and engine oil levels before operation.
Keep the cooling system clean and inspect hoses and connections for leaks.
Use the specified lubricant grade and compatible replacement parts.
Record service hours and maintenance activities.

Different XAS 98 versions may use different engines or configurations. Always identify the machine by its full model designation and serial number before ordering filters, service kits, or other spare parts.

Frequently Asked Questions (FAQ)

Which engine is fitted to the XAS 98?

Kubota engines are listed for applicable versions, including V1505 and V1505-T configurations. Verify the engine identification plate before ordering engine parts.

What makes the XAS 98 different from the smaller XAS 88?

While both machines look identical from the outside and share the same lightweight sub-750kg chassis, the XAS 98 is fine-tuned to deliver a higher free air delivery of 5.4 m³/min (190 CFM) compared to the XAS 88’s 5.0 m³/min (175 CFM). This extra flow is ideal if you need to run more tools simultaneously.

Can I tow the XATS 98 / XAS 98 without a commercial trailer license?

Yes. In most international regions (including Europe), trailers weighing under 750 kg do not require a special supplementary towing license. Because the XAS 98 is engineered to be under this weight limit when fully fueled, it can be towed behind a standard utility van or passenger vehicle.

How many pneumatic jackhammers can run off the XAS 98?

Equipped with 3 standard air outlets and a 190 CFM high-flow rate, the XAS 98 can concurrently power up to 3 heavy-duty paving breakers or up to 4 lighter handheld chipping hammers without losing operating pressure.

What is the fuel autonomy of the XAS 98 during a standard work shift?

Thanks to the highly efficient direct-injection diesel engine and an automatic stepless speed control that lowers engine RPM when air is not being consumed, the integrated 60-liter fuel tank provides enough autonomy for a full 8-to-10 hour working shift under variable contractor loads.
