Discussion Overview

The discussion centers around the search for a compact compressor capable of producing up to 100 bar (1450 psi) while operating on a maximum of 40V DC. Participants explore various options, specifications, and the feasibility of such a device.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant is looking for a compact compressor that meets specific pressure and voltage requirements.
  • Another participant mentions Jordair compressors, which can fill tanks to around 4500 psig but likely do not operate on 40V DC.
  • There is skepticism about the existence of a compressor that fits the size and pressure criteria, with one participant stating they believe it does not exist.
  • Participants discuss the possibility of using gas-powered options or converting to AC power, as small high-pressure compressors are not common in the market.
  • The RIX Microboost is mentioned as a small compressor, but it operates on AC power, not 40V DC.
  • One participant raises questions about the intended use of the compressed air, specifically whether it is for human breathing, and inquires about the required CFM (cubic feet per minute).
  • Air amplifiers are suggested as an alternative, though they require a separate compressed air supply, complicating the setup.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of finding a compressor that meets the specified criteria. There is no consensus on whether such a device exists or what the best alternatives might be.

Contextual Notes

Participants note limitations regarding the availability of compressors that operate on 40V DC and the challenges associated with high-pressure requirements in compact designs.

Compressor wanted -- produce up to 100 bar/1450 psi @ 40Vdc

I'm searching for a compressor that is compact but is able to produce up to 100 bar/1450 psi. It also should work on max 40V DC. Please say if you know similar compressors!
Thanx already :)
 
Engineering news on Phys.org
Jordair makes Breathing Air compressors for applications like SCUBA, SCBA (for firefighters), things like that.

These compressors can fill tanks up to ~4500 psig. They are not cheap, and I doubt they run on 40 V DC. 100 bar is very high, these aren't little handheld units, you realize, right?
 
Yes i realize that, but it still should fit in a 30cm by 20 cm. At least That would be optimum...
 
I don't think that exists.
 
Well what do you think is the smallest?
 
The ones by Jordair, probably... They're not much bigger, but they're bigger. http://jordair.ca/products/diveline.html

Also, unless you go with the gas powered option, you'll likely be looking at a power source requirement of 208, 230, or 460 V AC. Not many people make small, high pressure compressors. There just isn't really a market for it. Also, I don't think it's possible to get enough power out of a 40 V DC power supply to supply anywhere near 1500 psig.
 
The RIX Microboost is only 1/2 hp but the motors are AC. There are also small, air powered compressors such as from Haskel and Hydraulics International (they have a crappy website so give them a call). Also check with Shoebox. I realize none of these are driven by 40 VDC power but I don't think you'll find that. It's too oddball. Maybe convert to AC or run a DC powered low pressure air compressor for a booster? Good luck.
 
Are you compressing air for human breathing ?
What CFM do you require ?

Gas compressors are different to Hydraulic pumps. Gas compressors have less dead space = higher compression ratio, and a much greater compressed gas cooling requirement.
24VDC motors are widely available. For hydraulic equivalents, see this site;

I forgot about Air Amplifiers, only problem with them though is that you need a compressed air supply to feed them. So you'd need two systems running simultaneously (not a bad idea, just a lot bigger and more complex).
