Neutra-Safe Corp. has redesigned its 4-inch, tube style condensate neutralizers. The high capacity neutralizers now include all the same features that make Neutra-Safe’s 2-inch models so easy to install and service. Features of the new design include full opening integral union ends, bi-directional condensate flow, ¾-inch female NPT inlet/outlet tappings and ¾-inch male NPT x socket fittings. The unit also comes with snap-in mounting brackets included. The best features of the original 4-inch neutralizer remain, including a clear tube for easy visual inspection and patented integral union ends with O-ring seals for a leak-proof connection.
