Air Venturi Power Booster 4500 Reviews

Initial performance....

Dependability. It doesnt match the performance specifications listed by the manufacturer. It failed within 13 months. All maintenance was completed on time and as per the owners manual!

There is a reason why this product is no longer available. Im a little sceptical of the Air Venturi brand as it relates to high pressure air compressors to include the power booster product. Not worth the $ 500 cost.

Quiet, simple, much quicker than hand pump. Since there are no electric parts and it is lubricated it will probably last a long time.

Oil definition should be communicated even ahead of ordering. Standard description that it is not included as well.

Should be specific on what oil is needed. Used synthetic compressor oil. I am sure standard hydraulic would be bad as listed in the manual. Viscosity is significantly different for hydraulic oil. Pressure and CFM has to be enough to actuate the booster. 50 psi at least needed to get to 3000psi out on the booster so 60:1 boost. It is needed to be close to this pressure and at least 3 CFM available to make it actuate. You will need 75 psi at that rate min to get to 4500 psi and actuate, and it will be slow or you will use the booster on / off to build enough pressure and continue pumping. This will make it even slower. This is ok for me I already have the compressor and it is way easier than hand pumping. Unless I purchase a bottle I will likely never need to go above 3000psi at least with the guns I own now.

Unit is compact and light and easy to use Works as stated

Include information on proper fill oil ( brand ,type) Include a small amount of oil with unit

The unit requires a large amount of air to operate Do not think it will operate on a small compressor! It needs a high output shop compressor to be efficient If your compressor is less than 5cfm with a large storageyou will be disappointed

It is simple to use. Works great for filling guns. From 1000psi to 3000psi takes about 1:32 to fill the Gamo urban.

moister separator, the price, easy hook up

would be nice it the oil overflow cap was mounted on the side instead of under, or add leg mounts to raise it off the floor a little.

definitely need more than 5 cfm at 90 psi to get descent fill times, the setting only goes to 4000 psi but it is capable of 4500 psi. it does spray water out so you will need to raise it up a little to keep it from sitting in a puddle depending on how long you run it.

it does work well, but my compressor is a little small on the CFM's will get a new compressor when I can afford it. I may update as I use it more

quality control is a little lacking, manual said it was set at 3000 psi at factory, it wasn't. the female adapter was no good 7 of the 8 ball bearings were missing so once you put pressure to it to fill it would not release after opening pressure relief valve. the oil filler that was supplied arrive broken

It works like it should. It dose not make a lot of noise. It pumps my Bulldog from 1500 psi in 9 minutes and in less than 7 minutes from 2000. It pumps my Marauder from 2000 in 6 minutes . I'm using a brand new California Air Tools 10020C compressor.

It dose not come with oil. The instructions say use compressor oil or hydraulic oil. When I went to the hardware store they only had hydraulic oil. I called PA and they said synthetic 10W-30 could be used and not to use hydraulic oil. Comes in a really nice box....with only one plastic tie holding it together ? The instructions are lacking.

The water filter works and relieves it's self when pressure is disconnected. It makes a puddle. I'm not sure what happens when it becomes full during use ? My compressor puts out a lot of water . It seems to blow off at 60 psi and bounces between 40 and 60 psi. The pump starts right after you turn the booster on. The booster dose not get warm . It seems to get colder.

It's small and it doesn't require electricity. Easy to use right out of the box.

It is painfully slow to fill either Scuba or Carbon Fiber Tanks. I tried first with a 125psi 5.5SCFM compressor and gauge didn't even move once it got to 1500 psi. Not very efficient with the air that goes in the unit no matter how high the compressor capacity or the SCFM.

It's ok to refill your PCP rifle. If you want to use it to fill let's say an 80cf SCUBA tank it can take forever. I mean compressor running continuously for hours and hours.

not so sure yet ,, first off the output to the gun leaked and was as tight as it should be,, replaced with another with the exact thread pattern ,,leak stopped and it is more flexible than the stock output hose ,, the no kink hoses are the best ,,expensive but well worth the price and ya aint gotta fight it like the wire stranded stiff stock hose.will update when my new compressor arrives

add the no kink hose to the pump as a stock item and make it work on less input and cfm air pressure as i had to order a 6cfm at 90 psi compressor

you compressor must provide at least 5 to 6 cfm at 85 psi,, yes its rated at 90psi but 80 to 85psi is a little in my opinion safer

This thing pumps up my mrods in under 3 minutes it's the best purchase I ever made other than my mrods.

Only the price

I liked the very easy hook up. No assembly required. Everything was as quick. I used a 4CFM at 90PSI and still filled my 90 cu bottle under an hour. And topped off my Benjamin Armada .22 in 2.5 min. Definitely werth the $$

Nothing

Great product. I'm sure the stand alone compressors are great as well. For just starting out on PCP air guns this is a must
