The PressureWave™ series is constructed of a virgin polypropylene liner combined with an FDA approved high grade butyl diaphragm. This is hels against the wall of the tank with a steel clench ring. Water enters the tank through a patented stainless steel water connection. The diaphragm and liner are both reinforced in specific wear areas for longer life. All internal parts including the air valve are rounded to prevent piercingog the diaphragm in extreme conditions. The water connection uniquely provides a dual water/air seal ensuring leak free and maintenance free pressure vessel.
On the exterior the almond colored two-part polyurethane paint over an epoxy undercoating provides hundreds of hours of UV and salt spray protection.
