There is now a lifetime Warranty on all Dreamair Components with a 5 Year Warranty on the Dreamair Carbon Fiber Body.
This assumes a service of the gun once a year.
So are thee guns or loaders available for sale? Don't to seem to find any actual sales information. The site link shown on their facebook page is down.

The Dreamair e-shop website has never been up since a short time after the project started when it contained the initial photos and loading graphs demonstrating the CVT system effects. You can send a message on the Facebook page to buy a gun which are more or less made to order. The 100 cm gun with a single alloy barrel buried inside the carbon fibre stock is 950 euro when I last looked, but you will need to ask. To that you need to add the shipping. The “Dreamloader” comes with the “Dreamair” gun and is not available separately as I just found out. The hand pump and pressure gauge come with the gun as they are both threaded for the inlet port located underneath the muzzle. Eventually there will be an aluminium body “Dreamair” model similar to the initial guns seen in the early photos, but right now it is only the carbon fibre body version.

The aluminium barrel provides the bore that the piston slides back and forth in, the air tank is created inside the carbon fibre body. In that respect the Pelengas Carbon pneumovacuum gun is similar as the bulbous carbon fibre body contains the air tank.

Interestingly I just had a query from someone in the USA about an easier to load gun for his female partner. I suggested a Dreamair as it can be loaded with two hands and has the efficiency of a pneumatic and the power can be finely adjusted by changing the pressure. Ideal for someone who has trouble loading a band gun where bands are only available in set sizes. This is what I said.

"Pneumatic guns if pumped up to give performance are not necessarily easy to load. Basically you are doing with one hand what you normally do with two hands on a band gun. However because a pneumatic is more efficient the effort can be lower than on a band gun to achieve the same result.

Whatever system they use in the detail they all work the same way, the loading can be staged, but you have to do it in one go. On multi-band guns you can split the effort, so maybe a gun with many thinner bands might do the trick? Anyway the main pneumatic guns are Mares, Salvimar, Cressi Sub and Seac Sub. Replacement shafts are easier to find for the first two, in fact they use the same shaft tail. A generalist gun size is 85 cm or 90 cm, after that they are harder to load. Smaller guns are easy to load, but don’t shoot as far. The 70 cm can be difficult because it is between sizes in terms of most people’s limb lengths. Generally a pneumatic will shoot two line wraps, they will struggle to do three".

Followed by:

"Well there is a pneumatic gun that you can load with two hands and that is the Dreamair speargun. It looks like an Arbalete but is actually pneumatic powered. You can adjust the air pressure in the gun to get the loading effort right. They are made by a Greek guy and have been sold for a couple of years now. They only come in one length and that is 100 cm which is about right. It is not a supergun, just another way of doing it. Water never gets into the inner works as it uses a sealed axle behind the muzzle drums, they are not pulleys".

Some information supplied by the "Infinitengines" Company concerning the current gun's physical dimensions.

The size of the "Dreamair" speargun is 110 cm (130 cm overall length). The dimensions of the oval barrel tube are 55 mm x 38 mm. (Note that a "standard" pneumatic gun, e.g. Mares "Sten", has a 40 mm OD tank tube with a 38 mm ID.) The weight of the gun without the spear is 1800 g and the gun can shoot spears from 6.5 mm to 8 mm in diameter with 150 cm length; spear shafts of a diameter larger than 8 mm can be used if a flotation element is added to the gun. The "Dreamair" speargun can be manufactured in various barrel lengths.
The above quote was from 2016 for the aluminium body tube gun. The current all carbon fibre body gun weighs about 2.1 kg and is a 100 cm model weighed without the spear; both carbon fibre versions of the gun weigh about the same. Compare this with a C4 Urukay 120 cm at 2.57 kg with no spear and no bands, although it has a reel as standard. More mass in a gun results in less recoil, however you have to carry it before entering the dive location, hopefully it is only a short distance to the boat. Shore diving can mean trudging along a beach heading for the rocks, so you need to take into account the weight of the weapons that you will be carrying.
