Plastic Pneumatics Tanks / FRC1114

[RyanCahoon]

Having had the opportunity to check out 1114's robot at the Pittsburgh Regional this weekend, they had pneumatic tanks that appeared to be made of a plastic, and I was told they were about half the weight of the standard Clippard tanks. Anyone know where to find these, or something like them?

Thanks,

I'm looking into these now... They look very nice weight-wise.

Do they have the same thread sizes for KOP fittings?

According to he Pnueaire Tech rep, they are available in both 1/8" and 1/4" NPT. Burst pressure is rated at 500psi, and working pressure at 125 psi. A no brainer if you want, or need to, save some weight. Also relatively inexpensive, and have plastic mounting brackets available as well.

To the teams that used these:

How did you "prove" the working pressure is rated at 125 psi to your inspectors?

Is a print-out of the specs on their website sufficient, or is there a specsheet somewhere?

Thanks!

A printout would be perfect. It lists the important information right there.

Team 33 graciously gifted 4 of them to us for our Robot "Pneuman". We will be adding 4 of these for 9 clippards.

weight .50 compared to .88 ( roughly from memory)
cu in 44 compared to 16

We ordered the kewl standoffs for them too. I'll post pictures next week during our maintenance window.

No problem. You guys were so close on weight, and air is so critical to your design, it seemed like the right thing to do. One of the college students that helped found your team was a former 33 student, so we have carried a soft spot for your team for years.

I work for Liquidweb.com and we call what you did "Heroic". Here's a Heroic salute from the work battlelines--->

Pneuaire seems to have several websites selling their reservoir cartridges (www.smcpneumatics.com, www.coastpneumatics.com, www.poweraire.com; they share the same "online support" image and similar addresses). Their other websites indicate that the RC2.5x10 is actually ~30 cubic inches. But when 8 of these tanks requires 7 minutes to fill, the difference between 30 and 44 doesn't seem like much. =P

It looks like 1712 just found some breathing room.

I could be wrong, but the Clippard tank provided in the KOP is listed at 33 cu. in., making the plastic tank capacity about 25% greater. Anyone know for sure the weights of the plastic Pneuaire tank and the aluminum Clippard tank for comparison?

Just for additional consideration, in a long-term installation, I would prefer to use aluminum tanks. Plastic, over time, tends to creep and weaken, which should not be a problem on a FIRST robot.

where did you get the plastic board holding all your components?

It looks like perfed poly from AndyMark: http://www.andymark.com/ProductDetai...ctCode=am-0836

plastic is great for holding pneumatic pressure, or transmitting hydraulic pressure as long as it's thick enough to contain it.

for example
