Given its size and weight, the Bauer Junior II Specifications is one of the world’s smallest and lightest portable breathing air compressor system available in the market. But it’s not just about the size and weight that makes BAUER Junior II Specifications the most preferred portable compressor selling over 100,000 units around the globe, it has something to do with the technology behind it.

Considered as the heart of any compressor, the compressor block, especially from the Bauer Junior II Specifications, has been proven to be both durable and reliable where its compressor components can efficiently work for decades with minimal maintenance required.

Among the compact features of a Bauer Junior II Specifications is the plateau-shaped cylinders that have been relatively reduced in size while maintaining compression power and the built-in cooling system which partially stores cool high pressure air before it enters a scuba tank. It has an easy access oil filler neck, an oil dipstick and an oil drain valve that makes the task of checking and changing compressor oil very easy.

Check before Using

Let’s say you have purchased a brand new Bauer Junior II. After taking the compressor unit out of the packaging container, you need to check if there are damages caused by shipping. Otherwise, you need to send it back to your supplier.

Let’s say there’s no damage and want to try the compressor, you need to do some pre-starting checkup before you turn on the motor. First, check if there is compressor oil by pulling out the oil dipstick. Brand new compressor is already filled with compressor oil before getting out of the factory for shipment. But just in case there is none, then you need to add oil. But not just any oil (car engine oil is a BIG NO NO) as the Bauer Junior II has its own specified compressor oil.

After checking the compressor oil, insert the plastic intake filter tube to its receiving port hole. Turn the oil and water drain valve open then start the engine. Special orientation is needed if you are using a gasoline motor where you need to position the compressor in such a way that the fumes of the gasoline motor does not get into the plastic intake filter tube.

After starting the engine, allow the compressor to run for a couple of seconds. You can now attach the filling hose to the scuba tank but make sure the the tank valve and the filling hose valve are still close. Afterwards, close the oil and water drain valve. You will observe in the pressure gauge that the pressure will start to rise. You can begin opening the tank valve and the filling hose valve when pressure reaches 500 psi (35 bars). While filling the tank, it is best to open the drain valves allowing filtered water and oil out of the compressor.

Bauer Junior II Maintenance

With regards to compressor oil, make sure that it is always on the right level by checking the marker on the dipstick. Depending on the frequency of use, the oil quality may deteriorate and needs to be changed especially if the persistent color has turned black.

Located inside the filter system, the filter cartridge is the primary mechanism of the Bauer Junior II Specifications that separates oil and water giving you the highest air quality possible. But you have to remember that filter cartridges has a life span which will also depend on the frequency of usage. Meaning, it can only work for a certain number of airfills (hours) and a good indicator that its time to change filter is when the air it produces has a fouling smell or taste. But recording the number of working hours would be a time-consuming task, so installing a B-Timer would come in handy where the device gives you an indication to change the filter cartridge. If you are using gasoline motor, do not forget to check its engine oil. Otherwise, the motor will not work and so does the compressor.

PS. Do not attempt to change the compressor oil or the filter cartridge if you are not trained or certified to do so. Otherwise, you may compromise the performance of the compressor.

Now, are you still curious of the portable size of a Bauer Junior II? Just imagine this: it easily fits the trunk of most cars.
