PowerMax-HiPAC for Crosman 2240 - This Thread is Frozen

[Rodents' Rapture]

The "PowerMax-HiPAC" was designed with 2240 hunters in mind.

There's no longer a need to remodel your 2240 . The "PowerMax-HiPAC" HighPressureAirCylinder Kit is all you need. Go from 12g CO2 to HPA and back with no mods to your stock 2240. Just screw it in and you're ready to shoot Bulk CO2 or HPA to 1600psi whether you prefer a pump or bulk tank. The "PowerMax-HiPAC fills with CO2/N2 or HPA.

WANNNA DO SOME ALL-DAY PLINKING?
The "PowerMax-HiPAC" is easily removed to let you go from HPA to 12g CO2 whenever you choose

WANNA K.I.S.S.?
A simple change of the stock stricker spring with the custom #1grn spring and you'll shoot up to 2000psi.

WANNA GET HIGH, er?
Replace the custom #1grn spring with the custom #2red spring and you can easily get to 2500+ psi.

At 2000psi it's a good idea to replace the valve-to-cylinder seal washer. The PowerMax Kit comes with two (2) custom seals that are specifically engineered to hold up under 3000+ psi.

Precaution should be taken whenever using HPA. Secure the valve in the tube with a bigger set screw or anchor if you feel it necessary.

Once you've experience the capability of the "PowerMax-HiPAC" everything else is just a tune-up

The "PowerMaxHiPAC" is $60.50US, flat rate shipping is $7.50 within the 48. International shipping starts at $20.00US depending on location and customs requirements

So how many shots per fill? I assume it will increase the fps over the co2?

1-Price?
2-How about some pellet weights and chrony numbers to back up the product?
3-Shots per Air vs. Co2 fill?
Thanks

I ran some numbers today with a grn spring @ 2000psi, 7" barrel, Crosman 14.3gr Hollows at 2'
20 shots string
502.8
487.2
511.8
496.1
513.7
503.3
499.9
505.7
506.4
488.2
476.8
528.1
463.6
460.6
442.6
425.3
437.7
410.1
388.8
396.4

 It'll settle down in about 200-300 more rounds. It'll shoot better once the valve and barrel have had a break-in. I think 2240ers in the cold will love it. After all, it wasn't made with plinkiing in mind. That's what CO2 is for.

The price is $60.50, more chrony number are posted below

Here a link to some chrony numbers sent to me by a current user. Thanks Todd for sharing these with me that I may share them with others.:)

So you only get 3 shots per fill?

[Rodents' Rapture]

3 shots? 13 of 20 shots above the stated 460fps from a stock 2240 with nothing but a spring change. Shot less than 100 pells through it. Besides, how many kills shots does one need on a hunt. Three tree rats a day keep all tree rats away. It's a starting platform

[Rodents' Rapture]

I have several of these in stock for the 2240. I am currently completing the HiPAC for the 2250 and 60, along with the QB andHam 850mag.

K.I.S.S.?

Could you please be so kind and show us where the burst disk is?

Needed in case it fails (or the pumps' gauge fails and you overfill it by accident)

[Rodents' Rapture]

I'm glad you asked! Let me tell you about the "PowerMax" safety features

 There is no burst disk, nor is there a burst disk in the stock 2240. If the CO2 overheats in the summer sun and wants to explode there is no burst disk. However, safety measure are provider, thanks Crosman, so I took advantage of them. I'll get back to that in a second.

 The stock red-rubber seal is design to allow blow-by around 2200psi which is what I was told. The Instruction/Precaution flyer that comes with every unit I ship states it at 2000psi which is an extra precaution I chose to take. My custom seal is designed to allow blow-by around 3300psi which is less than 70% of the actual burst pressure and the maximum rated manufactured airgun hand pump pressure. I picked 3000psi as the safe operating pressure as I state in the Instruction/Precaution flyer.

 The seal is cut to a smaller ID than the valve inlet hole. This creates a cantilever over the valve inlet hole whereby any escaping air/gas can push out under the seal in the event of over-pressurization. You simlpy can't overtighten it by hand. We tried and tried and tried.

 Also as stated in the Instruction/Precaution flyer, the use of tools to install the PowerMax is a DON'T NEVER DO IT no-no. 

 The custom seal that come with every HiPAC is designed specifically for the 2240 valve relative to its' (seal) thickness. The ID, thickness, compression strength, recovery and elastisity was all engineered by my friend Mr. Fredricks. He did the numbers, mixed the compounds, made the rubber and really made the whole thing work.

 110deg /6hrs @ 4700psi did not exceed the burst pressure on the sealed test cylinder. The photo of the actual cylinder was still shown attached to the pump @ 3000psi. That photo is somewhere on some forum, in case you missed it.

 Now, about that safety feature I mentioned. I was told about this as a safety feature by one of the guys at Crosman. He didn't treally tell me about it. I pointed it out and he said I was right so here it is.

 At the top (seal) end of the valve the rim of the cup that holds the seal is curled in. Part of the safety feature. The bottom of the cup concaves slightly towards the center hole. Part of the safety feature. This cup, as it were, pockets the seal in place around all sides and prevents the seal from blowing out of place if it (seal) fails. Having the seal remain in place even if it fails creates an obstructed release flow of the air/gas. Crosman designed this safety feature into the valve by including a pressure relief hole in the side wall of this cup. If a seal leak occurs, air/gas will leak from around/under the seal through this relief hole. If a major seal failure occurs the blown seal will remain in place preventing the air/gas from expelling at an unobstructed rate. Air/gas will leak out at a faster rate but provided the tube has not been sealed around the valve the air/gas will expell through whatever holes there are in the tube.

 Any more questions? Feel free to ask.

Note the bigger valve set screw. This was done as an alternative to drilling holes in the tube to secure the valve. Slight modifications were made to the frame to accommodate the larger screw head

 You asked an honest question or so I thought. I answered it for you!  Well here's what you can do. Get one, try is, make an honest opinion like it or not. You keep trying to say it's unsafe but at the same time you keep blocking the honest opinions of actual users from your site. Why are the opinions and thoughts of people who use the PowerMax being blocked. Don't you feel your followers have a right to the truth. People who have something good to say about it get blocked? 

Rodents' Rapture has been edited by me (Truman) Sometimes, stuff said in the heat of the moment is just that! As for the other parts of this reply, I'll let it stand because I have no opinion on this topic!
