It only requires 15-20psi . Bicycle pumps have been used with great success.Check out this link to info from Walter Liese and Satish Kumar's Bamboo

>> Hi paulin, why do you need to go through all the trouble. Just make a air tight container, pressurize it using simple bicycle pump and then let the chemical (boron/borax) ooz out of the hose that are connected to the tank.

>> Hello,

>> I would like to treat bamboo poles with a chemical solution (boric-borax/ boron borate/borac? ). But we have some problem importing a pressure tank. At least for the beginning we would like to weld a metallic tank. What should be the dimensions (HxLxD)? How to operate for the chemical treatment (Quantity of poles at a time, solution, length of time, ...)? Note that the boiling will be done on firewood.
