Tips:This series includes trailer-type (XAS 185 KD) and vehicle-mounted (XAS 185 KDU) models to meet the needs of different scenarios.
As a trusted provider of compressed air solutions in the industrial field, our Atlas Copco XAS 185 series is a mobile diesel air compressor designed for high-intensity working environments. Its core advantages are high efficiency, reliability and low operating costs.
Product Introduction
The Atlas Copco 185 CFM series air compressors (such as the XAS 185 150/100 and the truck-mounted XAS 185 KDU) are diesel-driven, single-stage, oil-injected rotary screw compressors equipped with liquid-cooled Kubota engines (such as the V1505/V2403 models) that meet Tier 4 Final emission standards, providing high efficiency and low emissions. They offer a displacement range of 119–185 CFM and an operating pressure range of 58–150 psig (depending on the model). Equipped with the PACE intelligent control system, they dynamically adjust pressure and flow to optimize fuel efficiency (approximately 2.7 gph at full load). Their compact zinc steel housing (70–76 dB(A)) and portable design (some models have a dry weight of 825 kg) make them suitable for construction, mining, and industrial applications. They are widely used for pneumatic tooling (impact wrenches, nailers), sandblasting, and tire repair.

Product Features
1. Intelligent Adaptive Energy Saving System (PACE)
Atlas Copco XAS 185 is equipped with PACE technology as standard, which dynamically adjusts the engine speed and exhaust pressure by real-time monitoring of the gas demand of the tool. For example, it automatically reduces the speed to 1800 rpm at low load, reducing fuel consumption by 40%.
2.Reliability in extreme environments
Low-temperature start: Equipped with preheated coolant and lubricating oil system, it can still start normally in an environment of -13°F (-25°C);
High-temperature operation: independent dual-fan cooling system, supports continuous operation in a high-temperature environment of 122°F (50°C).
3. Ultra-quiet design
Multi-layer zinc steel soundproof cover + silencer intake system, the noise is controlled below 70 dB(A) (comparable products are generally >85 dB(A)), meeting the standards for urban night construction.

Product application areas
1.XAS 185 has become the core power source of pneumatic equipment in many industries with its high compatibility:
2.Construction site: driving impact wrenches (≥1/2"), concrete crushers, large nail guns, etc.
3.Industrial maintenance: supporting sandblasting machines to deal with bridge corrosion and ship painting, with an efficiency of 40 m²/hr;
4.Municipal services: road repair, pipeline cleaning, mobile tire inflation stations (pressure transient response <3 seconds);
5.Food/Pharmaceuticals: 10 ppm ultra-low oil-containing air meets oil-free contact-level tools (such as packaging machines, fermentation tank stirring).

Product durability details
1.Anti-corrosion structure: HardHat™ polyethylene cover + three-layer epoxy primer spray frame, anti-salt spray corrosion ability exceeds 1000 hours;
2.Anti-leakage design: The base has a 110% waste liquid holding capacity to prevent oil leakage from polluting the soil;
3.Direct drive technology: The engine and the screw are directly connected (without a gearbox), reducing transmission losses and reducing maintenance points by 60%.

Market authority proof
Industry benchmark status: There are more than 120,000 XAS 185 in service worldwide, and it was rated as the "most reliable small and medium-sized construction site compressor" by Construction Equipment magazine;
The first choice in the rental market: According to data from Canada's Gegra Equipment Rental Company, the return rate of this model is less than 2%, and the rental rate is 90%.
Service Commitment
1.Global Warranty: 3-year/6000-hour engine and main engine warranty (whichever comes first), 24-hour local technical support;
2.Accessories Supply: Global warehouses always have core accessories such as screw assemblies and control modules, and deliver within 72 hours;
3.Customized Training: Free operator safety courses (including VR simulators) and energy-saving management manuals.
FAQ
Q1: Can XAS 185 drive multiple large sandblasting equipment at the same time?
Two sandblasting tanks can be connected in parallel (single tank consumes 90 CFM). It is recommended to install an 8 gal buffer tank to cope with air pressure fluctuations.
Q2: Will the power drop when used at an altitude of 3,000 meters?
The high altitude compensation module is standard, and the output air pressure fluctuation rate is less than 5% within 5,000 meters.
Q3: How long is the oil change cycle?
When using the original lubricant (ParCool Green), the oil change interval is 1,000 hours or 1 year.
