The approximate size ratio of the { 4 in | 10.1 cm } air drive piston to the gas piston is 25:1. Nitrox Ready, the Mini Sport Booster is factory cleaned by Haskel for 100% Oxygen Service. As delivered, you can use it to boost pure oxygen, but it can also boost pure helium, pure air, as well as nitrox and trimix mixtures of those gases. (Note that depending on the physical properties of the gas being boosted, efficiency and fill times can vary considerably from those of pure oxygen.) The boosters from Dive Gear Express are also factory fresh production.

The very small size { 14 in L x 6 in W x 6.5 in H | 35.6 cm W x 15.2 cm H x 16.5 cm D } and weight { 12 lb | 5.4 kg } allow it to be conveniently transported. The Mini Sport Booster can fill cylinders up to 3300 psi and it can boost with source gas pressures as low as 100 psi. Popular with technical and rebreather divers, the Mini Sport Booster allows deco bottles, oxygen and diluent rebreather cylinders to be filled when low pressure compressed air is the only source of power available. Operating with a drive air pressure of just 140 psi means it can be supplied by the LP port of a typical SCUBA first stage regulator and tank.


Take a look at the fill times in the table below. For example, starting with a supply pressure of just 1000 psi, to fill an AL-19 cylinder to 3000 psi takes just 3 minutes. The Haskel Mini Sport Booster is reliable too, with a one year factory warranty. The Haskel name in boosters has long been recognized for their quality.

  • Low Weight Portability
  • Locking Speed Control Sound Muffler

  • Total Separation of Supply Gas and Drive Gas
