Homemade airbrush compressor

The OHP-10 fire extinguisher was produced as a receiver, with a declared volume of 8.7 liters, actually measured and amounting to 10.5 liters. A fire extinguisher gained internship at the enterprise. He simply went to the head of the fire safety department or xs as he is called, and asked if there was a decommissioned fire extinguisher. Gave him.

I must say right away, do not try to release its contents in the bathroom. While I was dragging him to the house, I went behind the garages and released there (it will bring a lot of childish pleasure;). a PM5 pressure switch was also purchased, designed for water, but suitable for air. I also bought two dehumidifier filters, and one automobile fuel one, of fine cleaning (I immediately put it on the compressor inlet.

I bought all sorts of adapters, crosspieces, also a reinforced PVC hose with an internal diameter of 10 mm. All that was included in the set, see the photo. I also acquired a valve (at first I thought that I would regulate the pressure, and that it was no different from the gearbox (naive).

After I figured out that the valve and the gearbox were all slightly different, I bought a gearbox with a pressure gauge, and a separate pressure gauge to measure the pressure inside the receiver. They also bought a thin hose xs what diameter, in a pet shop, costing as much as 10 rubles / meter :))). It is either silicone, or some kind of xs, but very flexible, lightweight and durable, there is nothing better for supplying an airbrush.

Well, of course, the same thing without the FUM tape, which is sold in any plumbing store.

First of all, we screw the balloon to the base (I think you’ll figure it out yourself, there are no tricks here). We take out all the goodness from the lid, and from the inside of the fire extinguisher, we leave only the cylinder itself and the lid.

Screw the pressure switch into the crosspiece through the adapter 1 / 2НР-1 / 4НР, screw the adapter 1 / 2НР-1 / 2НР from the side.

Next, screw the tee on the side.

On one side, we fasten to it a reducer with a 1 / 4HP thread through an adapter 1 / 2HP-1 / 4BP.

From the other end, also through the adapter 1 / 2НР-1 / 4ВН, screw a manometer with a thread of 1 / 4НР. On the opposite side of the cross, we screw in the valve (for bleeding air from the cylinder), which has a 1 / 2HP thread.

We screw the filter-water separator to the gearbox, which has a 1 / 4HP thread and goes straight to the gearbox. Here, the fact is that the filter should stand correctly (observe the top and bottom), and make sure that the drain hole is at the lowest point.

Next, from the inlet filter nozzle, we again insert the reinforced sling and bring it already to the compressor outlet pipe. how to fix this good there, I think you’ll come up with. I have a cunning system of several gaskets there and everything is clamped on top with a clamp.
