HEAP 1 Electric Air Compressor
Air-Cooled Efficiency
Built-in thermovents draw heat away from the motor during operation, keeping performance stable and extending service life. No water tanks or extra setup—just clean, reliable air cooling that keeps the HEAP 1 running smoothly wherever you refill.
Set it and forget it.
Set your target pressure and let the HEAP 1 do the rest. The compressor automatically stops when your preset level is reached, ensuring precise fills every time while protecting internal components from overpressure.
Clean, Oil-Free Output
The HEAP 1’s oil-free design keeps air clean and maintenance minimal. Paired with an integrated oil-water separator, it removes impurities and moisture so every refill is pure, dry, and ready for diving, paintball, or other high-performance applications.
Air supply for every scenario.
Whether you’re plugged in or off the grid, SMACO makes it easy to refill your tank anywhere.

Does the job. Gave me air for the tank . Quiet and easy to use. Turn the knob to watch pressure you like and it will stop there. Works with 12 volt, 110v and 220volt.
This is my second shot at purchasing a high pressure compressor such as this one. The other one I bought does the job, but this one is MUCH more versatile, easier to use, and has more features. Can run off of 12v DC or 120 AC or 240 AC. Really happy with this purchase!
Not to heavy and it's mostly quiet...ive had one that's quieter but it was also 3 times as much and 3 times as heavy.....so for the money its pretty great....not as a fast as my big one....but for you guys out there hand pumping, I suggest you get one of these, you will thank yourself
le vendeur s'ajuste tres rapidement quand il y a un probleme et je suis tres satisfait
I love how quickly the compressor works. It fills up my bottles faster than expected.I would highly recommend! I love how you could plug it in and use a car battery.
Fills 68ci 4500 tanks in about 45 min
Good product, quick no noise
È costoso ma il suo prezzo lo vale tutto, ottimo compressore
I use the compressor to fill my mini scuba tanks to 3,000 psi. Took 11 minutes to fill each tank.
zum Befüllen einfach Klasse ohne Wasser nicht zu laut und kompakt
I liked that came earlier then expected, thank you. It was received in perfect brand new condition no damage. This came with some awesome tools and parts. Made sure all screws were tight. Did pressure test like manual instructed. Passed, no leaks. Waited about ten minutes before releasing bleed off valve. I have a 3L tank that was down to 3,900 psi. Topped off at 4,500 psi. Took about six to eight minutes. Works great. I wish it came with a temperature gauge read out like others do. That’s not a deal breaker. I bought this to fill smaller tanks. For going out and topping off Airguns. Oh by the way it’s not real loud. The fans are louder then the pumping motor. My other unit that I have is louder. And that one only has one fan inside. And much slower on pumping. Yes I would recommend this to a friend. It all comes down to what one’s needs are. For me this fit the bill. God Bless and be safe!
Works great. Fills my tanks. Is light enough bto be portable.
It works alright so far Little Slow We will see
I am using this to fill paintball tanks and I have no complaints. Hook it up and turn it on, that simple. I have used it to fill my tank approximately 20 times and it is still going strong with no issues. Overall I am pleased and I would buy again. 5 STARS
Works fabulous and I love the compact size for easy carry. A must have emergency item for long trips in my opinion. Easy to figure out how to use and inflated efficiently and with good power. Not super noisy and really durable. Great quality for the price in my opinion. A great gift idea for someone who travels a lot.
Buen producto.
I was tired of paying to get my tanks filled to use my gigantic air rifles. Well, this does the job and I don't even have to leave my garage. Even my 72 cal monstrosity works just fine with what this can do.It's not that loud. I expected it to be louder than my normal air compressors, but it really isn't. It isn't exactly silent, but it's nowhere near as loud as I was expecting. It works on plain old 110v and I have yet to have a single problem with it.
This powerful little compressor arrived quickly and was packaged well. Pretty quiet when in use. Easy to hook up. Works on 12 volt or 120v hook up so great for car or home. Great buy for the money.
What a great way to refill my scuba tank and my paintball tank. This comes with all the necessary accessories to get you started. My favorite feature is the anti moisture mechanism to remove water from the air.
Great product. easy to set up and very versatile.
Da bes 1
I use it for refilling my Torch tank. It doesn't fill them as full as the welding store, but it saves me time, just set it up, let it go over night and it's done in the morning.
I got this for paintball tanks, and it works great. Quick refill. It's not quiet by any means, but it fills the tanks pretty quick, and if you use it outside, the sound isn't too noticeable. I like that it has a 12 volt option, so I can run it off the car battery and don't need to find a place to plug it in.The assembly quality is solid, I expect this to last a long time given how heavy it is, and the obvious attention to part quality.This unit is great for high pressure tank refills.
This has been a great asset to my paint ball team. We no longer have to pay the $10 to get the tanks aired up and only takes a few minutes. The quality of this machine is great and seems to be a great build.
This device blew me away. Comes with all the adapters so didn't need any to fill my PCP air rifle. Took about 5 mins to fill. Used it in 12v in the field, and at home 110v. Easy instructions, breeze to use. My friend has a 1 ltr scuba tank and fills it in no time. This is a life saver for compressed air! Pros, easy to use anywhere, fast cons, none, Price well worth it
This filled my 1L scuba tank to 3000psi in 28 minutes. This is important because every 30 minutes of run time, this has to shut down for cooling. Surprisingly the noise from the cooling fan is louder than the pump itself. This is loud, by the way, comparable to a large garage air compressor. It works good no problem with contaminants or smell.
Pneumatic pellet gun air tank fill.
Works as advertised. Very happy with this purchase. Using to refill my 1.5L tank, which I use to refill the little integrated tank on my .22 pellet air gun. NO MORE reliance on local scuba stores.
Nice quality product - Works great with our 1L scuba tank!
