Pneumatic No-Loss Drains (PNLD II)

The newly enhanced PNLD II units are heavy-duty industrial drain valves that remove condensate without wasting compressed air.

The pneumatically-powered PNLD II requires no electricity, pre-settings, or manual intervention. Designed to complement all compressed air systems including compressors, filters, water separators, dryers, coolers and receivers, the PNLD II is easy to install and will not clog.

A unique air valve design uses magnetic force to ensure a positive opening and closing that prevents attraction of metal particulate. Then an innovative ball valve support-and-positioning system prevents side-loading which causes premature sealing failure around the valve stem. Finally, a rifle-drilled discharge porting ensures that scale and rust exits through a fully ported 1.3 cm (1/2 in) ball valve.

The result? PNLD II saves enough compressed air to pay for itself in six months or less.
