Features

The Efficient Choice for Commercial and Industrial Applications

The PNLD II requires no electricity, pre-settings or manual intervention, making it ideal for use in commercial and industrial applications. Designed to work with a variety of system components including compressors, receiver tanks, in-line filters, water separators, dryers and coolers, the PNLD II is easy to install and operates virtually clog-free.

Superior Materials, Rugged Construction

To ensure maximum service life and compatibility, the PNLD II features a stainless steel float and air cylinder that accommodate higher operating pressures and resist deterioration from corrosion. The drain valves use Viton® seals to prevent deterioration from lubricant carryover in the condensate.

Robust Valve Design

The PNLD II features a unique air valve design that uses magnetic force to ensure a positive opening and closing to prevent metal particulate from clogging the drain. An innovative ball valve support and positioning system impedes side loading, which can cause premature sealing failure around the valve stem. A rifle-drilled discharge port ensures that scale and rust exits through the full-port ball valve.
