White color, outside volume 2 gallons, inside bladder holds about 2 gallons @ 60 psi input pressure

* Dimension: 9" diameter, 14" height, 1/4"MPT inlet connection

* Material:
Outside is steel, inside is a FDA approved food grade bladder. Stainless steel connection on top. Purified water only come in contact with bladder and the stainless steel connector on top. The tank is pre-charged to 7 psi.

If you'd like to know more.....
A pressure tank is used in RO systems to accumulate water and provide pressure at dispensing faucet. It has a water bladder inside the tank that holds the purified water, and outside the bladder is the compressed air. When you dispense water, the compressed air squeezes the bladder and forces the water out with pressure. You can connect several tanks together also to provide more water.
