Description
The Condair (Nortec) 1519040 steam cylinder is an OEM humidifier replacement part for electrode-style systems running on 208–240 V three-phase power. Often referred to as the 421/403 cylinder, it supports medium-capacity humidifiers (typically ~30 lbs/hr steam output). This cylinder houses the conductive electrodes and collects mineral buildup, which naturally occurs during operation; periodic replacement ensures efficient steam output and consistent humidity performance. It’s designed as a direct-swap OEM part for Condair/Nortec EL, NHEL, MES, NHTC, and NHPC series units.
