4WD Air Compressors

At Scintex we supply only the best, as we understand that when push comes to shove in the outback the last of your worries should be faulty equipment. Therefore we source only from reliable brands such as Sherpa Big Air and hand picked by Scintex for quality control assurance with more budget-friendly 12v/24v air compressor OEM alternatives. 

Our flagship air compressor is the Sherpa Big Air DC air compressor. This heavy duty, portable unit is perfect for 4wd enthusiasts who can appreciate faster inflation speeds which an electric motor can deliver. It can also be used for large trucks requiring high volumes of air or even used for running air tools in industrial applications.

The Sherpa Big Air is available in a 12V or 24V option and allows simple integration into onboard air systems. If you want a reliable, high performance air compressor thats made to last - look no further than the Sherpa Big Air.

Our collection also includes an onboard air compressor which is great for mounting into tight spaces on your 4wd. High quality, industrial grade units available in 12V and 24V options and delivering a 100% duty cycle and high discharge pressure.

To compliment the collection we also stock replacement air compressor tanks, sealed pressure switches and a 3 piece 1/4" plug kit so replacement parts are covered.

Our air compressors are of the highest quality with distribution of the the units now covering overseas markets such as the US and Canada.

For tyre inflation, airflow is usually the better indicator of how quickly a compressor can move air, while maximum pressure shows whether it can reach the required pressure. A compressor with high PSI but low airflow may still inflate large 4WD tyres slowly. Compare the stated litres per minute together with duty cycle, hose restrictions and the pressure at which airflow is measured.
Duty cycle describes how long a compressor can operate within a set period before it needs to cool. A 100% duty-cycle model is designed for continuous operation under its specified test conditions, while other compressors require rest periods. High ambient temperatures, restricted ventilation and high discharge pressure can increase heat, so installation and operating instructions remain important.
A portable compressor can be moved between vehicles and stored when not required, making it practical for occasional touring or multiple vehicles. An onboard system provides quicker access and can integrate with an air tank, pressure switch and fixed air outlets. Onboard installations require secure mounting, suitable wiring, ventilation and protection from water, heat and impact.
High-output compressors such as the Sherpa Big Air may operate selected air tools, but tool performance depends on sustained air consumption rather than maximum pressure alone. Many tools require an air receiver tank to manage short demand peaks. Compare the tool’s required free-air delivery with the compressor output and duty cycle before relying on it for workshop-style use.
High-performance compressors can draw substantial current, particularly during startup and at higher pressure. Cable size must suit the compressor current, system voltage and total cable length, with an appropriate fuse or circuit breaker located close to the power source. Short, well-terminated cables help prevent voltage drop, slow operation and overheated connections. Follow the product wiring diagram rather than using general accessory wiring.
