UMAREX PAC Eco - Silent PCP Air Compressor

The Umarex PAC Eco is a low-noise, mains-powered PCP compressor designed for shooters who are tired of sounding like they’re rebuilding a lawnmower every time they top up a cylinder. At around 60 dB, it’s quiet enough that you can actually use it at home without immediately becoming “that neighbour”.
 
It’s built for steady, controlled filling rather than fast industrial air dumping, which suits most individual PCP users far better than they’d like to admit.
 
Key Features
Ultra-quiet operation at approx. 60 dB
300 BAR maximum output pressure
Oil-free, water-free air output
Automatic shut-off at target pressure
Integrated overheat protection
Digital pressure control (1 BAR increments)
Built-in water trap system
Includes multiple adapter types (Foster QD, 1/8" BSP, M10, M10x1)
Compact vertical design for easy placement
 
Performance / Use Case
This is designed for regular PCP users who want reliable fills without the noise, heat, and drama of traditional high-output compressors.
 
With a flow rate of 1 L/min, it prioritises control and safety over speed. Filling a typical 500cc bottle 100BAR to 300BAR takes around 2 hours, which sounds slow until you realise you can leave it running unattended and come back to a full cylinder without lifting a hand pump once.
 
The low noise output is the real advantage here. It makes it practical for home use, shared spaces, or anywhere you don’t want to announce every fill cycle to the surrounding postcode.
 
Build & Design
The PAC Eco has a compact vertical layout, making it easy to store without dedicating half a workshop to it. At 6.3kg, it’s portable enough to move when needed but stable enough to sit in one place long term.
 
Cooling and safety systems are built in, including automatic shut-off and thermal protection, which helps prevent overheating during longer fills. The integrated water trap and oil-free operation reduce maintenance and eliminate the usual contamination risks associated with poorly managed compressed air systems.
 
Controls are straightforward, with a digital interface that lets you set target pressure and let the system handle the rest.

The PAC Eco isn’t trying to be fast or industrial, it’s trying to be usable in real-world environments where noise and convenience matter.
 
If you want rapid bulk filling, this isn’t it. If you want a quiet, set-and-forget compressor that fits into normal life without turning your garage into a workshop soundtrack, it makes a lot of sense.
