Page 2 - Air Venturi RovAir 4500 Portable Reviews

Light weight, well packaged, fast delivery Quiet operation.

Receiving a compressor that actually worked. 1st time out of the box I attempted to refill my pcp from 120 bar. Pump seemed to be working well , got to 200 bar and Pop! It Stopped filling. Very disappointing. Hand pumping over 200 BAR is a bear.

Prompt reply from customer service ... I used the provided return label and dropped it off at UPS store. Returned RovAir and now awaiting replacement. Will update review when this is resolved.

Compressor would not build pressure when i first tried it which was very frustrating. I had to take out the two green o-rings inside the female connection points on both ends of the hose and replaced them with two slightly bigger metric size o-rings and it built and held pressure. With the original o-rings there was too much play where it connects to the male foster fitting. After that I am happy with the purchase and I definitely recommend this as opposed to hand pumping your air rifles. Shipping was fast especially during a holiday and it arrived a day earlier.

I purchased the set of o-rings at my local HF store for cheap or any hardware store should also have some in stock.

I've had it a little over a week and has worked great! I've filled my cricket 30,rti prophet 22cal,Vulcan 3 22. Several times and worked great.

Nothing

Fast fill ups. Beat the hand pump by a mile Love the auto stop future

Little longer hose.

This thing is way more quiet than I anticipated. Fills the 3000 psi tank for the Sig MCX Virtus from almost empty in less than 5 minutes. I can shoot all day with little down time.

Price point if at all possible. It was tough to justify buying a compressor that was more expensive than my first PCP rifle.

I've never used a hand pump for a PCP. That will not change now that I have this compressor.

This fills my PCP quickly and to a consistent pressure every time and without breaking a sweat. It sure beats pumping by hand.

The integrated AC to DC converter runs whenever the unit is plugged in, even with the power switch off. I would suggest powering the internal AC to DC converter only when the power switch is switched to AC on.

Compared to using a hand pump to pressurize your PCP air reservoir, this is much easier. You should expect to go through pellets much more quickly, but also expect your accuracy to improve with all of the extra trigger practice you will get.

Extremely efficient and super quite, for what it is capable of.

Nothing.

This is a great price point for such a useful product!

It is relatively quite. Works great a needs no maintenance

Nice piece-a-goods. Nothing to add that hasn't been said in prior 5-star reviews. This really frees me up: I'm shooting a LOT more, now that I'm no longer dependent on the hassle of getting my large CF tank filled at the dive shop. Also, dumping (previously valuable) air to adjust regulators for converted CO2 guns is no longer to be avoided at all cost.

A larger, oil filled gage would be nice. But not if it increased the price by much.

Actually, what I want to know: has anyone run this @ 220 volts? Any benefits? Per instructions, you remove the cover, do unspecified rewiring, then use an unspecified "adapter" with the provided power cord. I don't understand how you get 220v, which requires 4 conductors, through a standard 3-conductor 110v cord. But if someone's done it, please share.

Packaging was unbelievably good. I’m using it now as a storage case for it. Only used it once so far. It took 6 minutes to take my Avenge-X .22 synthetic from 1000 psi to 4351 psi. It just sat there running nice and smooth and was purring like a kitten. The quality of the build of the unit and components look really good. I was impressed. Hope it keeps doing this. Time will tell.

So far, everything is perfect as is!

After only using it once, I would go out on a limb and say this is the one you want! I fired it up against a 1000 psi back pressure in the guns tube and it acted like it started with zero back pressure. Every thing about this says quality. As soon as I saw the shipping packaging, I knew I made the right choice!

Fills quickly and efficiently. 1000 times better than hand pumping. A must have!

The fact you can’t leave it plugged in because the fans keep running. So I have to unplug it after use. So that means I plug it in to use it and then unplug it repeatedly.

Lobe this compressor. Best way to fill pcp air rifle , no water needed to cool and also has auto shutoff

Nonoe

It's compact, not too heavy, not overly noisy, fills my 100cc Stormrider, and 50cc bandit in very little time. No sweat beads roll off my head and I don't have to wait for my heart rate to come down after working the stirrup pump for half an hour.

Make the whip just a little longer for convenience sake.

Read the manual thoroughly. Do as it says

light weight, compact, easy to store, quiet, not loud at all, fills my Benjamin Marauder quickly from empty. Fair price. Nice carry handle. Solid build quality. Still need to see how it is longevity. Though I don’t currently use this feature, it can run off of a 12 vdc car battery if you are in place without easy access to AC power.

I use to use bottle tanks for my Marauder, but it was getting harder to find places that can fill tanks to 4000 psi. And using a hand pump was too taxing and took too long. I wish they had compressors this quiet, compact and at this price point years ago. I would not hesitate to buy again. PyramydAir has a great product.

This air compressor is compact, lightweight and fills my 200-bar precision air cylinder within one minute. I also like the fact that no maintenance is required other than replacing the air filter on occasion.

I would like to see a larger pressure gauge such as the one that comes on the Air Venturi Krypton 4500 PSI Compressor.

In my opinion, this unit is worth the expense vs using a manual pump. After using once a day for several months I've had no issues.

Fairly compact, easy to use, seems durable. Time will tell.

Don't think I would change anything.

a lot better than hand pumping i have 2 pcp air rifles i will be shooting them a lot more i will be 70 yrs old

the compressor tops off air guns in 3 min

Received July 5th 2023 Checking pressure time on arrival running unit off a fully charged 12 volt 100 ah Battleborn Lithium battery, using dead end adapter plug 0 to 200 bar 25 seconds, 0 to 300 bar 35 secs

Air Venturi should check China's tolerances on foster adapters on fill hose to tight. Hose is useless. Foster fittings on supplied fill hose didn't fit Weihrauch fill probe, Would not go onto the Fx Crown Mk 2 male fill port had to use the fill hose from my Omega 75 cf. tank to use Rovair.

Time will tell hopefully Air Venturi can service this unit if it needs repair, Unlike Crossman (Benjamin traveler) that lasted 2 years and they do not service their unit.
