How to Build a Air Compressor on a Budget

What happens here

The creator reviews the total cost breakdown for the air compressor build. The major components included a Harbor Freight 5 HP compressor pump ($240), an EMZ 5 HP single-phase 230V motor ($290), a 3/4-inch NPT jumper hose ($39), a 3/4-inch compressor check valve ($18), electrical wiring and a 30-amp plug ($51), drain components ($24), intake components ($10), a 67-inch belt ($11), and a Harbor Freight lubricator/regulator ($80). An optional pump oil drain extension cost $12. With the addition of a $40 used tank, the total project cost was approximately $770 (rounded to $800). This figure significantly undercuts the cost of a comparable new commercial unit. He notes that costs could be further reduced by choosing smaller HP components or purchasing materials from different retailers. He concludes by emphasizing the value of this high-performance, budget-friendly setup for demanding DIY projects.

Goal: Understand the total cost and value of the DIY air compressor build.

up and it works. All right, ignore my shitty handwriting. Let's talk prices. So, we have our 5 horsepower Harbor Freight compressor pump. This bad boy that I for the big black twin cylinder back there, that was $240. Now, with a 20% off coupon like they're running this weekend, this weekend as in December 13th or whatever it is today, um you can get this cheaper. You could probably get this for $200 roughly. And then EMZ motor, 5 horsepower, singlephase, 230 volts. I picked it up for roughly $290. >> [snorts] >> You could go with a Viva Vivore 5 horsepower singlephase for like in the 170 range. You could also go up to like a Century or um I forget whatever name other names are up in the 500 $600, 700 range. You could you could go crazy with the motor if you wanted. I've heard bad things about the Vivore. I've heard all right things about the EMZs. The Centuries are pretty good. So, you get crazy with this. This is just what I went through. So about 300 bucks that was shipped to my door. And then this jumper hose here, the 3/4 in jumper hose, MPT, was $34 on Amazon, which in my mind is a little bit cheaper than buying all 3/4 in black iron. Then you have a 3/4 in compressor check valve. That was the one that this line goes into. That was $18 on Amazon. You can get that size, whatever size you want to get it. I just went 3/4 to 3/4 because that's what I wanted. Our electrical portion of a compressor, so I got 13 ft of 10 gauge is $2.64 a foot. You can get that cheaper, I'm sure. And a 30 amp plug. The total was $51 for our electrical. Now, if you go shorter plug, cheaper, whatever, 10 gauge, whatever, you can get that down. Our intake, we're going to skip here. We're going to stand intakes. Our intake was a two 2 in to 3/4 in bushing and a 90° elbow. That combined was $10. Picked that up my local plumbing store. All right. Now, our drain, the one at the bottom of the tank, that was a 2 inch to a half inch bushing, 8 inch by half inch black iron pipe, 1/2 in 90/2 in valve, that was roughly $24. And that's up here at Ace Ace Hardware. We don't have a Home Depot or nothing. So, if you had a Home Depot or a Menard's, you could certainly probably do that cheaper. All right. Next, the belt I got at AutoZone. was $11. And that's really about it. Oh, I guess our I should add on here. Our pulley for our motor was $20 on Amazon as well. So, our pulley was 20 bucks. So, about $310 for the motor setup. Um, and that's just what you would find at the store.…
