Air Venturi MK4 by Hill Reviews

well made, simple maintenance and repair, great backup but get an air tank or an electric compressor for regular use

the air filters should be permanently mounted and easily maintained, yes you should filter the air going in and coming out of the pump if you want your toys to last

keep it clean and spend your time shooting instead of repairing

Does the job!

Longer hose.

The biggest plus for me, was the cost of this pump vs the cost of a compressor. I have just purchased my very first PCP Pellet gun, so being new to these guns, and on a fixed retirees budget, it was a good fit for me. The overall quality of the pump is evident as soon as you open the box. It just feels like it will last, it is way heavier than a normal bicycle pump.

If possible, I would like to see the effort it takes to pump the last 30 or 40 strokes reduced , even if it meant an additional 30 or 40 strokes to reach the higher pressures. Maybe an electric motor attachment as an option? I am 68 and It is a real workout to fill my rifle, but then once it is filled, I can then shoot with out pumping anything for a long time! That, I like!!

The main thing is not to expect it to pump up your gun like you remember pumping up your bicycle tires, it looks just like a regular bicycle pump, but that is all, everything else is different, it is heavier, much harder to pump, and you do need to learn how to pause at the end of each stroke. The cost is I believe reasonable for the convenience it offers, you can take it anywhere, And High pressure pumps are very expensive high tech pieces of equipment.

Nice and compact. Solid, robust construction

The base model does not come with an air dryer. The next version of this same pump does have an air dryer accessory.

Seems to be a high quality pump. Fills my gun with reasonable effort.

Expensive! Similar looking pumps were available for much less, but they all disappeared. It was either buy this one or have a useless gun! Did not come with the correct adapter to connect my charging probe. Adapter was also on backorder! Had to order adapter elsewhere. Had a hard time stopping leaks between the hose end and the probe, but finally got there.

Absolutely the best of the many pumps I've used.

Include the quick disconnect air nozzle like you do on the model with the air dryer.

Some have said the only difference between this and the model that comes with the air dryer is the actual air dryer. In fact this model also does not include the quick disconnect air hose end, which the air dryer model does. So that's another $20 you'll need to spend if you don't have one and don't have a 1/4" screw-in air nozzle.

It works. However my Benjamin and my Chinese version worked too...up to a point. This pump does have a good feel and hopefully will last a long time.

great pump .as with all pcp pumps ,they are not for the weak hearted . hill is the original ultra high pressure pump dont fall for the cheap off shore junk

I think they should all come with the dry pack filter . the one I got did not have that system on it as its an option thats an extra 50 clams.There is no way on earth that thing should cost that much . If it was 20 bucks ,that would be a fair price...

by using the proper technique ,you should have zero problems with this pump . If you are handy with a lathe and a piece of 2 inch round delrin or aluminum ,you can make the adapter for the drypack and then go to harbor freight and get the drypack for 7bucks. thats what I did.

Seems to be made very well. It was very easy to assemble and there were no leaks with any of the fittings. Pressure gauge is easy to read.

Using plastic for the foot pad is not a deal breaker (reason for four star value rating) but making it somewhat "beefier" (thicker) would seem to keep pace with the rest of the quality of the pump. A movable arrow on the gauge would be useful for "targeting" you desired pressure at a glance. A simple Velcro strap included for use in keeping the hose in place when not is use would be a plus.

It took me 286 pumps to fill my new Gauntlet from empty to 3K psi. My first 150 pumps were at 50 pump intervals with a short rest in between (for me) and to allow the pump to cool. Thereafter, I was using 25 pump intervals with a short (mmmm....actually a little longer) rest in between until I reached 3,000 psi. The pump performed flawlessly. This was my first experience with a PCP. I will likely gravitate towards the SCBA (not SCUBA) tank at some point but for now this pump serves my needs for air just fine. In the event I can be convinced that the air dryer is a necessity, I may add one later, but for now I'm not sure since it does not eliminate 100%. Feel free to comment...

nicely build, long hose, easier to pump than my previous brand.

none

you need adapter if you use it for a benjamin brand

It seems to be a very well made pump. I have used it a dozen or more times to fill my Benjamin Marauder rifle which has a 215cc cylinder. It takes me about 100 strokes to go from 1500 to 2500 psi on my rifle's gauge. I am 70 years old and weigh 160 pounds and am in pretty good physical condition. I do have to apply most of my weight in a rapid motion to complete the entire pump stroke, especially as the pressure increases. My rifle's max pressure is 3000 psi and I am comfortable filling it to that level with this pump. I am not sure I would want to attempt to fill a gun to higher pressure with this pump, even though it is rated up to 4500 psi.

Possibly bigger footpads. Although I recognize there is a trade-off with pump storage and portability.

Purchased this about a year ago and finally tried it for the 1st time for a Benjamin Marauder pistol. The first attempt fresh from the box - I gues never used but not too easy to tell - except this pump got close to 1000psi and each stroke was very inconsistent and unsmooth - as in 1/2 the thrusts and pulls felt nothing was in them. Another flaw is the pump gauge - which should immediately match pistol pressure gauge on plugging in or pumping. The dial doesn't move anymore after my second attempt. This pump fails out-0of-the-box and the squeeks and little hisses where seals should be were all nudged up - not too tight. I'm puzzled that a very expense addition to air gunning sinks on every level for me. Wish it weren't so but I got a hell of lemon. Shoulds tried it when showed up but put it away till I purchased two benjamin high-pressure air guns and now I have time it sucks to chase this expensive option again. Hope better luck to all.

A brand new pump with every function consistently reliable to advertised specs, and lasts as advertised long as you take care of it. Reasonable.

Track where you buy everything. I bought this pump roughly a year ago. Just wanted to start compression gunning - kinda limp the pump gauge failed after pumping about 1000 psi into my benjamin marauder. After 1st try the gauge was dead and the pump seemed sloppily inconsistent. I get how to inflate with a push pump and not sloppy. Just sucks to get a lemon from the factory. I'm a little "gun shy" now that my one high pressure MK IV failed on arrival so alternatives are in considerations.

Well made heavy duty and built to last.

would like to see a adaptor to snap the air hose in to keep the hose off the ground when not in use.

Smooth, comes with lube. Easy maintenance. Good reputation.

Grips are an uncomfortable texture and could be thicker.

The pump works as advertised. It is a work-out to top off my Urban and Marauder, but exercise is good for you!!! Build quality is good, feels like pump will last. No questionable Chinese junk here!!!

Plastic base may be a weak spot, time will tell.

Take your time pumping, use legs and upper body to make full pump cycles and slight pause at extension and again at compression. I am 68 years young and find this a workout, but very do able.

Easy to use and very well made. I should have bought one a year ago.

I wouldn't make any changes!

What I do is fill what I can from my SCBA bottle, and then top the guns off with the hand pump. Works well for me!

sturdy and easy to use and very mobile

make sure fitting is right

Please show me how to pump the MK4.

Very disappointed that the quick connect fitting is not provided with the pump. Expect to pay another $25 for the fitting before you can actually pump anything up. What is it?

Easy to assemble, easy to understand manual, easy to do maintenance and they even send the silicone grease for the tube.

Would have rather had metal foot stand instead of plastic but works just fine the way it is.

Had a few different hand pumps and this one seems to put a little more air out and pump the gun up faster but hand pumping is work after 2500psi and if you target shoot a lot you may want to consider a electric compressor.

Not a lot of effort for a manual pump.

The intake is close to the ground where even a basic dust filter would be nice.

it takes 110-120 strokes to bring the 215cc tank on my Armada from 2000psi to 3000psi.
