[PSUBS-MAILIST] Manipulator arm

[swaters@waters-ks.com via Personal_Submersibles]

Is Gamma all air cylinders? Do you just use a air compressor? What happens to the air once it is in the cylinder and you want to lower the cylinder? Is it recompressed or somehow expelled? I really don't know crap about pnematics. Haha. Why do all the subs use hydrolics and not air. For example hydro-lek?
Thanks,
Scott Waters

Scott,
Not sure why you want hydraulic cylinders.  You want air cylinders, they are light weight and all aluminum.  If you use 2 in bore air cylinders you can run on a 500 psi system.  Also air cylinders typically have 5/8 rods and that is the most important part.  The rod size is what the water pressure is pushing back against you system.  Air cylinders have a single o ring on the piston and are cheap and easy to replace. If you want ss rods then just replace the chrome rods when they wear out.  I made my own rods for Gamma, easy peezy.

Are you using hydraulic cylinders or air cylinders.
