I Built my OWN Custom Compressor Beast (50 CFM+) Mirror Polished Guards Fabrication (Part 5.2)

Hi Everyone,

Welcome back to my YouTube channel. Some time ago, I nearly finished this unique bespoke project: a 50 CFM compressor. I have been extremely occupied with my PhD study and the recent live streaming to finalize these complex custom guards.

This compressor, constructed by me, is the largest single-phase reciprocating piston compressor worldwide, with a capacity of 50 CFM and a power output of 11 hp/8 kW.

In Part 5.1, I commenced the fabrication of two aesthetically pleasing yet effective industrial stainless-steel guards, employing an 8 by 4 sheet of 304 grade stainless steel mesh. Profile 3” by ½”. There I constructed a customized high-precision jig that accurately conforms to the shape and volume of the guards to be manufactured.

In this video, Part 5.2, I continue with the custom project by fabricating the two stainless-steel guards for the rear of the compressor. The guards will now consist of four components: two rear guard panels and two front guard panels, which will be affixed directly to the backing panels.

I have conducted 24 live streaming on the manufacturing of these custom guards on my channel.
This video Part 5.2 is a summary of live streams from live Part 9 to live stream Part 10. This main video includes a greater volume of work overall, however with diminished detail regarding each time-consuming or specific task.

As I say, this video takes us to the end of Part 10 of the live streams that I have covered on my channel. This means that main video Part 5.3 will start of a live stream Part 11 and move rapidly near the end. Part 5.3 will follow very soon of the construction of the backing guards.

However, it is important to note that because of the guard's quality, there is still a substantial amount of detail to address. The assembly of the guards will need to be split into 4 sections (This being section 2) for Part 5 of this project. It is hoped that an additional section 5 would not be necessary; we shall see.

Additional fascinating projects, such as my custom compressor construction, my unique Green Beast E-bike, my distinctive mechanical iris/aperture, and my exceptional smart glove, will soon accompany this endeavour.

For any content related to the vessel's tumbling, the attachment of accessories, the production of stainless tensioners, or the complete build process, there are six or seven major videos available on my channel.

Thank you, and goodbye
Jeffrey

So, in Part 3.3 (below) I demonstrated the fill time (to be 1.56s) empty vessel, and the psi of vessel (was set at 150PSI), the size of vessel (is 270ltrs), and with those variables, inputted into the fluid dynamics formula, this beast proves to be 50CFM (see video description for this). It takes less than 30 seconds to get from 110psi to 150psi, once the vessel drops pressure, using both pumps.

To calculate a compressor's CFM (Cubic Feet per Minute), you can use well known fluid dynamics formula: CFM = (V * ∆P) / (T * 14.7), where V is the air receiver (tank) volume in Cubic feet (cu ft or ft³), ∆P is the pressure change in PSI during pump-up, T is the pump-up time in minutes, and 14.7 is atmospheric pressure in PSI. Alternatively, you can look at the manufacturer's specifications, but some have asked a good question here.

Or CFM = (Air Flow Rate) / (Air Density)

So here you go.

The capacity of the air tank in cubic feet. You can convert gallons to cubic feet by multiplying by 0.1336.

V (Volume of Air Receiver in Cubic Feet): 270ltr = 9.53 ft³ (On the tank of my Vessel (270ltrs)
The difference between the starting and ending pressure of the tank during the pump-up process (ending pressure - starting pressure). ∆P (Change in Pressure in PSI): 0 - 150PSI (Demonstrated in final video)

The time it takes for the compressor to fill the tank from the starting pressure to the ending pressure.

T (Time in Seconds): 1min.55s (in my test video) or let’s just say 2 minutes for the formula (Demonstrated in final video) from empty vessel (shown/no editing in video).
A standard reference point.

14.7 (Atmospheric Pressure in PSI): 14.7 Sea level here in the land of Ireland.
This represents the volume of compressed air the compressor delivers per minute.
CFM (Cubic Feet per Minute): ? (What you want to know)

Therefore.
If my tank has a volume of 270ltrs (which is 9.53 cubic feet), a pressure change of 150PSI, and the pump-up time is 1min55 seconds, then the CFM calculation would be: CFM = (9.53 * 150) / (2 * 14.7) ≈ 48.622 CFM
