Altaros Double Booster – B2B Edition

We have made a new version of our popular booster:

Shortcut B2B means Bottle to Bottle which means that it is primarily intended to use the low remaining pressure in the cylinder to fill another smaller cylinder, or PCP airgun tank.

This version therefore allows you to use the pressure below 200bar in your main bottle to fill your airgun or a small smaller bottle to a full 300bar and thus ensure a full shot count of your airgun.

Compared to the current single-piston variants on the market, it is up to 2 times more efficient (you fill twice as many bottles) and many times faster + many other benefits and improvements

More information you will find in the video, or on Military airgun e-shop.

New booster and its endurance

At the end of this year, we have reached a new milestone. An Advanced Booster that we use in our workshop has been running for 4 years now and has filled the equivalent of 2,000 pieces of 4L bottles from 200 to 300 bar. The maintenance consisted only in lubricating and replacing the seal from 95% of that was the high-pressure piston seal. After the last upgrade, we achieve the filling of 100 bottles without the need for maintenance with this 4-year-old booster.

Animated video how compressor booster work

Because we continually strive to improve as the booster compressor and also user awareness about Compressor  function ,  we partnered with Mekanizmalar and let him create this animation video, which should further clarify the principle and function of our booster compressor. I want to thank Mr. Seyhan Ersoy for very good handling on this animation video.

Example how fast will compressor purchase cost be back

Often purchase of compressors  is not just about shooter confort, it can be suitable investment with a quick return of your funds. By adjusting the input data in this example, you can calculate for yourself how quickly your purchase returns. Apart from purely a matter of finances you will also buy for yourself sense of independence and that is for many people priceless.
Data contained in this model were obtained from  one user In Czech Republic, for which I thank him. So this data correspond to this specific user, for another users it will be different because you  will have another price for filling,  another distances, another bottle volume,  etc., etc. Each person value own time diferently , so I used only a statistical average wages ( in Czech republic ).

Price for filling bottles in filling station: =  0,72 USD/l x 7l =5,04 USD+ extra charges when filling up 7l  1,4 USD =

6,44 USD/per 7 liter bottle

5,96 Euro/per 7 liter bottle
Filling station is at a distance around 23Km x2 =  46km x 0,156 USD/km ( the average price per kilometer )

Transport cost =7,2 USD

Transport cost =6,67 Euro

Time need to get to filling station 40min = 1h 20min + 10 min spend at filling station = 1,5h x Median of net wages = 735,72/month / 160h/month = 4,56 USD/ hour   approximately 4 USD per hour

Time spent 1,5 hour  = 6 USD

Time spent 1,5 hour  = 5,56 Euro
Total sum:
Price for filling is   6,44 USD /  5,96 euro

Transport cost  is   7,2 USD / 6,67 Euro

Time cost   6 USD  /  5,56 Euro


Total =      20 USD per bottle     18,5 Euro per bottle

Price for 7L bottle filling ( elektricity ) with Altaros 1,5 kW  x 4hour x 0,16 USD/kWh = almost 1 USD

Otto had filled his bottle of 7 liters on average 3 times a month and used hand pump when needed.

With our compressor currently fills around 6 bottles per month.

Return of purchase cost for Otto if he fill 3 time per month is:

20 USD /bottle  x 3 = 60 USD  – 3x 1USD (electricity for altaros compresssor) = 57 USD/month

Compressor cost is  639 USD / 57 = 11,21 month.

From example  is obvious that with performance of 3 filled bottles per month would be his purchase price for the compressor returned in less than one year.

If he fill 6 bottles per month like he do with compressor now then compressor cost would be back in half year.

Improvements and final price adjustment

With the new year also comes a slight increase in the price of $ 36.
The reasons for the price increase are as follows:
Added paintball coupling with a reduction male / male.

paintball-coupling pin-male-male







Inlet pressure pin can be unscrewed ( thread G ¼ ) and can be easily replaced. America, Europe, Australia each use  different filling pin. Plus there are a number of other filling pins standards.


Used high tech lubricant, which also greatly increase the life of the seal and parts.
Higher fees for export documents to third countries (non EU countries).
Surface finish for all parts is more expensive.

Christmas can cause delayed delivery+ Winter holiday

Winter is here and Christmas is coming. Delivery time can be much longer because postal services are overwhelmed and weather is unpredictable too. Keep in mind that goods is sent from Czech republic and any snow calamity on shipping route can prolong delivery.

We will have Christmas holiday from 23th. December to 2nd. January.

Wish you all Peaceful Christmas and great New Year .

A few adjustments for safe transportation

For reasons of increased safety against damage during transportation will be black bleed screw which is on the multifunction valve comes unscrewed and placed in a compartment on the lid of the compressor unit. Before the first start of the compressor simply screwed into the multifunction valve.

For the same reason it was also changed compressor unit input supply pin , which during transport is also located inside the lid of the compressor. When screwing on the compressor, do not use any tools. Screw him just using your fingers. At the bottom of the filling pin is o-ring to ensure a seal and It is not necessary to preload the threads. When using a wrench or pliers when tightening you could damage the moisture separator, so screwing filling pin only using your fingers!
