UMAREX PAC 900 - Workshop PCP Air Compressor

The PAC 900 is a straightforward, mains-powered PCP compressor built for home workshop use. No batteries, no pretending it’s portable, this is a plug-it-in and leave-it-there setup for regular filling.
It sits in that middle ground where it’s more capable than entry-level units, but not trying to be a full industrial system.
 
Key Features
230V mains-powered stationary compressor
7 L/min (FAD) inflation rate
Maximum pressure up to 300 BAR
Oil-free and water-free operation
Adjustable auto shut-off (1 BAR increments)
Integrated overheat protection
Replaceable filter sponge
Foster quick disconnect fill system
Multi-adapter compatibility (1/8", M10, M10x1)
 
Performance / Use Case
The PAC 900 is designed for regular home use, filling rifles and smaller cylinders without needing a full workshop setup.
 
With a 7 L/min flow rate, it’s noticeably quicker than low-end compressors but still controlled enough for safe, steady fills. It’s well suited to topping up rifles or filling cylinders up to 1 litre in a single run.
 
The 30-minute max run time is worth noting. It’s not built for long continuous sessions or large-volume fills, but for typical individual use, it’s more than enough.
 
Build & Design
At 6.6kg, it’s relatively compact for a workshop compressor and easy enough to move if needed, though it’s clearly intended to live on a bench or floor space rather than travel around.
 
The layout is simple and functional, with a clear digital display for setting and monitoring pressure. Built-in safety systems include automatic shut-off and thermal protection, which help prevent issues during repeated use.
 
Noise sits around 78 dB, so it’s not exactly quiet, but fairly typical for this level of output.

The PAC 900 is a solid, no-nonsense workshop compressor for regular PCP users. It’s not portable, and it’s not designed for large tanks, but it covers everyday filling duties reliably without overcomplicating things.
 
If you want something simple that lives in the workshop and just gets on with the job, this fits that role without trying to be clever about it.
