6x2 and 6x4 Chassis | Oil-Free Dry Bulk Air Compressors | XK Series

The XK series of truck mounted screw compressors offer a robust, high flow, oil free, contactless, low maintenance solution, designed for the contaminant free discharge of a wide range of dry bulk product types. Our XK12 is designed for efficient discharge of high density powder products, such as cement, while our XK18 is a multipurpose compressor, offering consistent discharge of multiple granular materials. The XK compressors are manufactured to operate at a constant 2 bar tank pressure to ensure an optimum discharge time. 

Compact Chassis Fit
Designed for easy integration on bulk tanker vehicles

Proven Low Outlet Temperature Throughout Speed Range of Machine

The XK has class leading low discharge outlet temperatures making it the perfect machine for discharging products that are sensitive to high temperatures.

Low Maintenance

A simple service, carried out every 12 months allows for your vehicle downtime to be kept to a minimum, ensuring that your machines can be operating at 100% efficiency, year round.

Compact Size & Lightweight

Our small size and light build results in greater operational efficiency through weight saving and a simplified drive method, meaning the XK is suitable for various chassis configurations.

Contaminant Free, Guaranteed

Our XK series are built to be oil free and contactless. An air gap between compressor gearbox and airend ensures that absolutely no oil can enter into the compressor’s airflow, meaning your critical product remains oil and contaminant free.

Discover how a lighter, more compact compressor installation can help improve payload capacity and reduce transportation costs. Use our calculator to estimate the potential savings for your operation in just a few clicks.

Dry Bulk

Our range of dry bulk blowers and compressors are designed to discharge your bulk materials at optimum rates in the safest way possible.

Key Industries Served

Cement & Building Materials
Efficient unloading of cement, fly ash, lime, mortar mixes, and other construction powders.

Food & Beverage
Safe handling of flour, sugar, starch, cocoa, and other food-grade bulk ingredients where product purity is essential.

Agriculture & Animal Feed
Reliable discharge of animal feed, grain by-products, and agricultural powders transported in bulk tankers.

Chemical Processing
Suitable for transporting and unloading dry chemical powders that require clean, contaminant-free conveying air.

Mounting

The compact shape and size of the XK compressor make it ideal for mounting inside the chassis on most vehicles to enable low cost direct PTO driving, meaning a simpler installation process. A through shaft allows clockwise or anticlockwise input drive rotation with mounting points on either side of the truck mounted compressor to provide further flexibility.

Torque Coupling

Unique Torque limiting coupling that fits directly onto the XK drive shaft is specially designed to protect the gearbox PTO from overloading and causing any potential damage.

Drive Options

The XK series can be driven hydraulically, via prop shaft, or coupled to electric motor. A wide range of installation options gives you the flexibility to run your vehicle exactly as you need it.

Filters

Every machine is supplied with a commissioning filter, which is removed after a vigorous test procedure on the vehicle.

Ancillary Options

The XK12/18 are supplied with a 2.5 & 2.2 bar relief valve, respectively, to protect the machines from over pressurization. Other ancillaries include air inlet filter, check valve and flange pack, as well as multiple silencer options.
