Building a gas air compressor is not as difficult as you might think. This blog post will provide an overview of how to build a gas air compressor, including all of these 11 steps.
How to Build a Gas Air Compressor
Step 1: Supplies & Tools
The first thing you will want to do is gather all of the supplies and tools that you’ll need for this project. You can use either a new or used tank, but make sure it isn’t rusted out on the inside. A steel tank should be fine, though, because we won’t be storing any flammable liquids in it.
You’ll also need an air compressor pump (the faster flow rating, the better), valves with enough connectors to fit your hose sizes (air chuck if you’re using one). Other items needed are quick disconnects like these, tanks pressure gauge, oiler bottle like this. Also, don’t forget about safety equipment such as gloves and goggles! Once you have everything together, you can move on to the next step.
Step 2: Disconnect the Compressor
It is important that you remove any air from your compressor. This can be done by following steps on your owner’s manual or watching this video. Once all of the pressure has been released, it’s safe to continue to the next step.
Step 3: Remove the Tank
Now that you have removed all of the pressure from your compressor, it’s time to remove the tank. This can be done by removing screws or bolts that attach them to other parts and lifting them out.
Remember: it should still feel heavy even after all of the air has been let out! If not, make sure there is no oil left inside because this will drastically reduce its weight. The next step is important in determining if we need a new pump or not; check for leaks!
Step 4: Check for Leaks
After you’ve properly disconnected everything with your compressor, inspect each piece carefully, looking for any small holes where air may escape when put back together again. Make sure every connection point (where hoses attach, for example) is nice and tight.
If you do find any leaks, it’s time to get your replacement parts! Leaks can be found by spraying with soapy water (bubbles will appear if there are holes), putting a light layer of oil around the connections (if you see wet spots on your work area or hear hissing sounds releasing air), or using an electronic leak detector like this.
Step 5: Find Your Pump Location
Now that we have successfully taken apart our compressor without breaking anything too bad, let’s find where we want to mount it.
It needs to stay clean and dry at all times because rust clogs up the valves, and moisture ruins them. We’ll also need to make sure it’s on the ground (or a sturdy table/shelf) to keep everything stable.
Step 6: Make Space for Your Tank!
If you’re using new parts, there should be nothing in your way of getting this compressor up and running quickly. This doesn’t apply if you’re trying to use some old equipment as I did; no matter what size tank you have, they are always bulky until empty because compressed air takes up so much room!
The good idea is to cut out pieces of wood or metal around your tank that can slide out easily after mounting it against another wall or behind a big piece of furniture. If space isn’t at a minimum already, though, find a solid surface where we can attach the tank and be sure to use brackets or bolts, so it doesn’t move around.
Step 7: Mount the Tank
This step is much easier if you have a small compressor like I do because we don’t need anything too heavy-duty that can handle larger equipment (unless you’re using an old truck air compressor). Use whatever parts came with your pump for this; they should fit together perfectly!
If not, make sure everything fits tightly before moving onto valve installation. Remember, safety first! To keep our hose from unraveling as well as wearing out over time, always put them on one side of any connection point (never both sides!) and tighten until snug; never cranked down hard unless there’s no other but to break something in order to fix it!
Step 8: Attach the Hoses to Your Tank and Compressor
Now that your tank is mounted, we can attach our hoses. This step really depends on how you plan on using this air compressor. If you’re trying to use a large machine or anything else with more power, make sure whatever hose has less pressure going through it (lower PSI rating) attaches to the part of your pump where there are fewer bubbles coming out from behind.
The other end should go over toward any areas that need compressed air such as an industrial grinder or sander/polisher for cars or furniture, basically anywhere where people will be standing nearby so safety goggles should always be used unless they don’t mind the occasional bit of dust or dirt flying into their face.
Step 9: Connect Your Hoses to Air Distribution Equipment (if any)
Now it’s time for smaller machines like grinders, sanding equipment, etc., but first, you need air hoses that can handle these types of jobs! We highly recommend buying a good quality compressor hose kit because they are reliable and made out of high-grade materials, so they won’t snap apart under pressure over time.
Just remember to read where each one goes on your chosen machine before putting them together! If there’s no place for an accessory kit, then use lots of Teflon tape around all threaded connections beforehand, starting with half turns at first until everything is nice and tight without the chance of air leaks.
Step 10: Connect Your Tools to the Hose End(s)
Once your hoses are connected, it’s time to put them on any tools you want! This is a pretty straightforward process until we get near the end. Make sure not to attach anything with a negative PSI rating (such as sanding equipment at home or grinding/cutting equipment in an industrial setting) directly onto another tool that has more pressure.
They can’t handle this kind of abuse over time and will eventually give out before their warranty expires if used like this regularly. Suppose one hose isn’t doing enough work for what you need done use two instead so there’s no risk of having too little power or causing damage when the machine simply can’t handle the PSI rating of another tool!
Step 11: Check Hoses for Leaks and Tightness
Before turning on your air compressor, make sure to check all connections for leaks or loose fittings. This is an easy step but very important because you won’t know there’s a problem until the worst possible moment when it decides to explode in your face!
A good rule of thumb is to tighten down every connection with Teflon tape beforehand, use two hoses if one isn’t enough (they are usually sold together), replace any part that looks worn out, etc. Then go on to this next step, assuming everything will work perfectly!
You can never be too careful about safety, so just double-check everything after installation, and we’ll be alright. The last thing anyone wants is to be covered in oil and dirt from a piece of equipment that failed when it should have been okay!
You have now built your very own DIY gas air compressor! Congratulations on a job well done, and enjoy the fruits of your labor. You can also ask a professional to help you if this is too difficult of a project.
