i thought these are used to run pneumatic piston recovery pumps like the Haskel ext420. I think the MVP run them as well.
Not really sure…thats what i see these 3 phase compressors used for though.

Specifically, to run pneumatic explosion proof pumps in a C1D1 rated environment. Also to dry lab glass after cleaning, but just as a secondary use.

Are you talking about air compressors or gas compressors for flammable solvents?
Because either way, oilless compressors are generally total dog shit. They’re louder, they wear out faster and generate way more heat than their oil-filled competition.
I have to ask, why do you think people would want oil free compressors in a lab/extraction environment? I have a bit of experience with the CMEP-OL pumps and nothing nice to say about them.
On the air compression side, unless those compressors are C1D1 rated as well as oil-free, they would generally be placed outside of the extraction area, and well outside of anywhere they could suck in flammable solvent fumes. Given the relatively small size of most extraction booths, I wouldn’t want to listen to the drone of ANY compressor given the option. You’d be deaf in a week.
If you are concerned about air quality, I think your best bet is to invest in a good air filter/dryer set (think like auto body shops use) and a refrigerated air dryer to make sure you aren’t sending any humid air towards pneumatic diaphragm pumps that are operated at low temps. I have definitely seen some Ingersoll pumps ice up the exhaust muffler because of the low temp they’re being run at which causes them to slow to a crawl or stop entirely.
I’m talking about air compressors. I’ve seen some Instagram posts about people setting up 30HP air compressors in their extraction laboratory. I’m assuming they use the compressor to power other equipment they are using. And it looks like from killa and futures comments that they use these air compressors to run their recovery pumps.

Ya exactly. And they are usually put in a machine room

Thank you,
Can you run pneumatic piston recovery pumps without an air compressor? For example, killa said the MVP and Haskel can run off of an air compressor. It would really suck if the MVP or Haskel were useless without a 20k compressor.
Just for clarification while we are talking… air compressors are not used for heating/cooling circulators - simply large scale solvent recovery?
If you know someone who has a 20/30HP compressor for solvent recovery… Do they rent or own?
Check it out…
“Proper operation of the Haskel EXT420 pumps will require
the following additional equipment:
• Compressed air source capable of providing
approximately 25 CFM of air at 90 psi (6.2 bar) or higher
(Compressor must be located in an area away from the
LPG gasses)
• Compressed air filter filtering to 40 microns or better
• Drive Air Pressure Regulator
• Drive Air Speed Control Valve - such as a Gate Valve or
a Globe Valve (not a Ball Valve)”

~10hp of screw compressor per haskel
*edit - rental is generally not a good idea. buy a low hours used unit if the price tag for new is too high

No, you can’t run pneumatic (pressurized air) driven pumps without a pneumatic drive source. That’s why the labs you see have purchased air compressors. It is like having a steam turbine, you must have a means to supply steam to the turbine, or the equipment doesn’t operate. If the air compressor fails, the hydrocarbon extractor can’t be operated.
Renting equipment which is required to operate other equipment that a company owns, which costs a lot more (closed loop hydrocarbon extraction systems) doesn’t make much sense to most… unless there’s factors I’ve missed… Companies who need these air compressors purchase them.
I’ve primarily seen oil-bath twin-screw type compressors used to power Haskels. (Of course, equipped with the required oil separator). Most opt for refrigerative drier equipped compressors, since these pumps prefer to see clean, DRY, unlubricated air.
Since these pumps rarely need to be used at their maximum speed (and thusly maximum air consumption) I’ve been able to get away with about ~7hp of air compressor per Haskel, but agree that ‘budgeting’ 10hp per pump is the proper way to do it. Also lowers the duty cycle of the compressor which’ll increase your service intervals.
