Alkin W31 Mariner HPA Compressor

Today I went to visit my good friend Doug Noble to check out a new compressor he had just received from Alkin. I had several tanks that needed to be refilled so was eager to get up to his place to check it out.

Alkin Compressors was established in 1990 by Engineer Erol Çiprut. Production activities take place in Menderes, Izmir at our 16500m2 site with 3500m2 indoors. Today their products appeal to different sectors, they offer fast, high quality service and their recognition in domestic and foreign markets is rising. Alkin is a leading supplier of compressors in Turkey and since foundation they are proud to say a great proportion of their production is exported abroad to countries including USA, Canada, France, Russia, Indonesia, South Korea, Australia, UAE, Finland, Sweden, the United Kingdom amongst others. Research and Development work continues in order to provide useful additions to their product range, continuous development and increased options for customers.

I looked over the unit and was immediately impressed with the build quality and the obvious quality of all the components and fittings. This is a very large industrial type unit that you would expect to find in a Dive shop, pretty much the ultimate for any Airgun enthusiast.

Doug and I had 6 tanks to fill so we figured it would be a good workout for the compressors main voyage. Doug started the compressor that I had anticipated being very loud considering how large it is, this was not the case at all. The Alkin is very quiet and has little vibration, this is due to the low RPM of the motor as well as the beefy frame and rubber feet. This unit came with all the fittings, fill yoke etc, VERY nice quality gauge, hoses and lines.

(NOTE)This fast, robust compressor can fill SCBA, paintball or SCUBA tank quickly and run at low RPM.  The advantage of the low RPM is less heat build up making your compressor last much longer (lifetime for most PCP users) and a big plus is your tank will lose less psi as it cools and you will keep your high PSI fill pressure.

This model is the 3.7 CFM and is a 3 stage unit that’s designed to run very conservatively to aid in running cooler than most compressors of this size. The heads have large cooling fins as well as aluminum head caps that really keep the temperatures down. We measured the temperature under the highest loads at 147 degrees. The side of the case has a very conveniently placed window to check oil levels.

The Alkin does have an oil/moisture separator that has a bleed for each stage of the compressor. This unit provides the cleanest air possible that means that our Airguns will LOVE IT. The purifier cartridge is easily repackable as well.

The on/off switch is large and easy to maneuver as well as the hour meter that helps us keep track of maintenance. The Alkin requires an oil change approximately ever 100 hours, this is a very long time and makes this unit near maintenance free.

Every nut and bolt on this unit is built to last and is covered by Alkins 2 year warranty. Most of the tanks we filled took between five and eight minutes depending on the size and starting pressures. This compressor is very high end and something that has been designed to run forever with normal maintenance.


I had a great time checking out this compressor and appreciate getting to fill several of my tanks with it. The Alkin is truly one of the best units available but just not widely known as an option for the serious Airgunner. I will enclose the short video documenting my time with the compressor along with the link to where to buy this unit.
