Drive Gas Adapter for Haskel
Drive Gas Adapter for Haskel
  • Standard BC quick-connect fitting to NPT 1/2"-14
  • Use BC hose w/ first stage as drive gas supply
  • Compatible with the Haskel Mini Sport Booster

This adapter contains a standard low pressure BC quick connect post to 1/4" NPT male fitting, assembled with a 1/4" NPT female to 1/2" NPT male adapter for your Haskel booster. This assembly allows you to use a BC inflator hose connected to the low pressure port of a standard scuba first stage regulator and air tank as your drive gas supply, thus eliminating the need for a low pressure drive gas compressor.

Drive Gas Options for the Haskel Mini Sport Booster

The Haskel Mini Sport Booster MSB-9000 is normally driven with the BC inflator hose off the first stage of any diving regulator using a SCUBA tank for the air supply. That allows the booster to be highly portable, operating in locations where no electrical outlet is available. Rather than a SCUBA tank, it can be more convenient and cost effective to drive the booster from a portable reciprocating single-stage piston oil-free low-pressure 'shop air' compressor powered by ordinary household electrical current.

For a drive gas compressor, the air volume rating (typically in cubic-feet-per-minute or CFM) will determine the maximum booster cycle speed and the air pressure rating (typically pounds-per-square-inch or PSI) will determine the maximum boost pressure. In a pinch, almost any air compressor that can deliver at least 1.5 CFM will work although the booster will be quite slow and may not be able to achieve maximum boost pressure. The 3 to 6 CFM range compressors are adequate for most boosting applications although the boost may pause occasionally while the compressor catches up and the boost cycle time will be noticeably slower approaching higher boost pressures (not necessarily a bad thing). The 7 to 10 CFM range shop air compressors with a large reservoir tank capable of maintaining a constant regulated 140 PSI will produce the best results for boosting. Haskel recommends not exceeding 150 PSI at any time.

Depending on ambient air conditions, the need to manually empty the compressor condensate during operation can be frequent so consider including an auto-drain feature. The design of the MSB-9000 is such that the drive gas section is completely separated from the boost gas section, however we recommend additional particle and condensate filtration on the air line output. With the higher volume compressors, add a variable flow control valve in the air line close to the booster itself in order to manage the cycle speed of the booster. Haskel recommends not exceeding 60 cycles per minute continuously, but slower is better especially when boosting oxygen. The MSB-9000 drive gas input fitting is 1/2" NPT female, but the typical shop air line fitting is 1/4" NPT, so an adapter will be needed plus a high-flow quick-connect coupler compatible with the air line from the compressor.

There are a lot of sources for these kinds of compressors and accessories; home or hardware stores as well as specialty suppliers and of course on-line. We find the prices can vary considerably so it pays to shop around for the best value but you should be able to find something suitable for a few hundred dollars.
