There was a hiccup with this order because the first one arrived damaged, but that was sorted out and now I have a fully functional compressor. My thoughts after assembling and trying it out: it is very quiet - even more so since I added two 200mm lengths of 9mm silicone tube, one to the inlet port of each air filter. That makes a big difference to the noise level and is worth doing. It does lack an inline water/oil separator but that can easily be added at minimal cost and is easy to do. The regulator offers two output ports although I can only attach a hose to one of them - the other being blocked by the handle. However, when I add the water separator that will move the ports a couple of inches forward and it will then be accessible so not a problem. The 50ltr tanks fills quickly, within a couple of minutes, so there is plenty of power provided by the two motors. Edit: All these budget compressors seem to come with a very short power cord, this one is no exception. To avoid having to use yet another mains extension I put a longer 15ft lead on mine. It's an easy job - pop one screw off the black plastic cover and the three terminals are easily accessible. Advisable to use crimp terminals on the wires rather than clamp onto the bare copper. Edit 2: Some weeks later, I decided not to add the water separator to the end of the regulator on the compressor because that connection is fragile enough without any additional length sticking out - with that tacked on the end it would be just asking to get knocked with a high risk of the threaded connection being broken. So I removed the quick-connect fitting which allowed me to directly attach a 2M whip hose (thus avoiding the handle) which leads to a water separator mounted away from the compressor (photo). That still leaves the front facing quick connector on the compressor available for other tools. One other issue: the tank water drain valve is not located at the lowest point but somewhat up and to one side. That means it won't drain out the water properly unless you tip the compressor over to compensate. Not a big problem you just have to remember to do it.

Nice compressor unit. It arrived very well packaged, although one of the grab handles on the box was damaged, but the product was not. Assembled easily, although I dont understand why the bolts holding the feet in place were 12mm on the bolt and 13mm on the nut. The bolts for the wheels are posidrive on one side and 17mm nuts on the other. The compressor uses Euro air couplings which work well enough. The compressor is far quieter than any I have bought previously and it does its job well. The only thing I dont like is the housings for the capacitors are just pushed in place whereas it is obvious from the design that originally they were screwed into position, which would have been a far more satifactory arrangement. In operation the capacitor housings seem fairly resilient (they dont fall off easily) and Im guessing that it reduces the cost of manufacture not having to put extra captive nuts on the machine. Overall a nicely packaged machine. that functions well and the neighbours cant hear running.

The DKIEI 25L Oil-Free Air Compressor offers a balance of performance and convenience for users seeking a quiet, low-maintenance solution for light to moderate tasks. I was very surprised with the low noise and i can have it in the workshop and not outside in the weather. pleased with flow rate, quality and price.

Comfortable sound when in use

I don't want to be too negative here. The compressor works well, is quiet and fulfills my needs. Having said that, I seriously doubt the claim to be 2.5HP. It's the same size motor as seen on other units, but they only claim to be 1HP. I also measured the power and it only consumes 700 watts (slightly less than 1HP) at full load. The second point is that this compressor does not include a pressure regulator (as stated in the ad), so the full 115PSI is fed out to the airline. Not a problem for me, but if it was used for paint spraying, it would probably give erratic results. My solution was to buy and fit a regulator (~£7 on eBay).

Nice compressor very quiet thanks

Good little compressor i use it mainly for airbrush painting but also cleaning brushes on our vax hoover + tyre pressures on the motorhome and car not sure if it could cope with painting large car panels though, if thats what you want to do i would probably recommend a larger compressor .

Very noisy sent it back.
