The Basics

Omega AC-1a




 Starting Up the AC-1a


The Support Kit: AC-1a

How to Order and the Price


The AC1-a is the latest version of our price beating, electric powered compressor.

Quieter than ever, the AC-1a is more compact, and boasts a new grease injection system.

It weighs in at 27kg, so is most definitely portable. It works with the minimum of maintenance. 

It comes in sturdy outer packaging with improved styrofoam boxes within.

Just some of the extras supplied include: maintenance kit, Purple Ice lubricant & Antifreeze, a high pressure hose with quick connect, a manual, and a 1 year warranty.

The  Omega with its quick connect is also ideal to fill your rifle or mini, portable tanks.

Please note: not certified for scuba use.

  • 4500 psi Output

  • Easy Adjust Auto- Pressure Shutoff

  • Super quiet compared to other compressors

  • New grease injection system.

  • Improved internal seals and systems.

  • Self-Servicable:  Tools and Spares Included)

  • Fill Times (approx):     Rifle: 3-4 minutes

  • 3l tank top up, 100 to 300bar: 45m

  • If you are filling just rifles, and given the average rifle fill is only 2-3 mins, then you will naturally vent moisture from the system when you de-pressurise the hose to disconnect it from the rifle. 

  • EVERY AC-1a is tested by us before onward shipping.

To start for the first time, begin with adding the Purple Ice, then the anti- freeze, and top up with regular water, but not distilled water. Spring water (still) is probably best. 

DO NOT operate the Omega compressor without having added water. The water is essential to cooling the compressor.

The AirCharger has no automatic venting system so you must remember to go back to the machine every 10 or 15 minutes to vent manually the moisture which collects during the compression process.

The Omega AirCharger comes with a basic maintenance kit. It comprises various parts: a several spare burst discs, tools, a special piston spanner, and a sensibly written manual. Also included are two plastic bottles, 1of anti-freeze and 1 of 'Purple Ice' which must be put into the water reservoir before it is finally topped up with clean water.

If there's a compressor problem which your local distributer or one which Gilbert Distribution can't fix, then the AirCharger's designer is just a quick email away from your service centre.
