The Ingersoll-Rand System Saver Drains have an electronic level sensing capability which only discharges when condensate is present, thus preventing unnecessary loss of valuable compressed air. This intelligent sensing system operates with all levels of condensate from 100% oil to 100% water. The System Saver Drains can be purchased as a bare drain valve or as a kit. The kit simplifies installation by supplying not only the bare drain valve, but also a ball valve and an adapter fitting.
