  • Filling times almost cut in half compared to the Pocket Air, as well as noise and vibration.
  • More demanding in terms of maintenance and operation, which I hope will be reflected in its service life.

For pressurizing small bottles up to 3L and air rifles, it is ideal.

  • It works perfectly
  • Excellent manual of Czech language
  • Perfectly functioning separator
  • Missing thermometer
  • Water splashing from the separator during blow-off on the front side of the compressor as well as on the cooling fan

  • After setup according to the instructions, it works perfectly on the first try. 👍
  • Shipping by GLS is not great. Even tape marked FRAGILE doesn't help. Luckily, the compressor packaging from the manufacturer is of good quality and nothing got damaged...
