X-Air 350-12bar 175psi 355cfm Mobile Compressor

The Atlas Copco X-Air 350-12bar 175psi 355cfm mobile compressor delivers 355 cfm (10 m³/min) at 12 bar (175 psi) from a Cummins-powered, towable package. It suits shotcrete, blasting, drilling support and construction air supply.

Compressor Overview

The Atlas Copco X-Air 350-12 is a diesel-driven portable screw compressor that delivers 355 cfm (10 m³/min) of free air at 12 bar (175 psi). It combines Atlas Copco’s in-house screw element with a Cummins engine, and the design focuses on three things: size, flow and fuel efficiency. It is a compact unit that supplies enough air for demanding jobs while keeping fuel use and service effort low.

Atlas Copco has built portable air compressors since 1905, when it introduced the first mobile air compressor powered by an internal combustion engine. The X-Air range reflects more than ten years of continuous development.

Technical Specifications

Why Choose the X-Air 350-12?

1. High pressure in a compact package.
At 12 bar, this unit covers work that 7 bar or 10 bar machines cannot handle. Atlas Copco lists 7–12 bar for shotcrete applications, and the 350-12 sits at the top of that range. Its box dimensions are 2568 × 1350 × 1808 mm, and it weighs 1,600 kg without the undercarriage.

2. Built for hot and cold sites.
The standard operating range is -10°C to +50°C without aftercooler (-10°C to +45°C with aftercooler). An enhanced cooling system supports high ambient temperatures. With the optional cold start kit, the unit can start down to -20°C.

3. Lower fuel cost.
The system matches engine speed to air demand. This brings the greatest fuel savings at partial load. The 175-litre fuel tank gives long autonomy between refuelling.

4. Designed for uptime.
Simple vessel design for easy service
Heavy-duty air filter with safety cartridge as standard
Additional fuel filter as standard to protect the engine
Metal braided hoses for safety and longevity
Integrated top tank to reduce leak risk and corrosion
Top-mounted muffler to reduce fire risk and heat load

5. Environmental protection.
The optional spillage-free frame helps avoid cleanup costs. It also supports compliance with mining and construction site regulations.

Typical Applications

Shotcrete spraying: The 12 bar pressure suits the 7–12 bar range Atlas Copco lists for shotcrete.
Abrasive blasting: Sandblasting and surface preparation for steel structures, pipelines and tanks.
Handheld pneumatic tools: Breakers, rock drills and other air tools on construction and civil sites.
Cable blowing and utility work: Support for telecom and utility installation.
General site air supply: The one G1 1/2 and three G3/4 outlets let several tools run at once.

A note on pressure flexibility: The 350-12 is a fixed-pressure model. If you need to switch between several pressure settings on one machine, consider the X-Air 400-12 PACE. PACE is Atlas Copco’s electronic pressure regulation system, and it adjusts pressure in 0.1 bar steps. If your work is mainly at 12 bar, the 350-12 is the simpler and more economical choice.

Optional Equipment

Depending on your project, you can add:

Aftercooler with water separator and filters (for drier air in blasting and painting)
Cold start kit
Refinery kit
Spillage-free frame
Jockey wheel and support leg
Skid or single axle
Mounted support
ECO-mode

Fleet Management

Atlas Copco’s FLEETLINK telematics system helps optimize fleet usage and reduce maintenance. It is useful for rental companies and contractors who run several machines.

How to Select the Right Size
Add up your tools’ air consumption. Check each tool’s required cfm at its working pressure, and leave a margin for hose losses and future tools.
Confirm the working pressure. The 350-12 gives up to 12 bar, so verify that your tools do not need more.
Check your site climate. Use the temperature ranges above, and add the aftercooler or cold start kit where needed.
Confirm emission rules. Choose T2 or T3 according to your local regulations.
