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.
