Harwil L-21N Level Switch

Harwil^® type L-21N industrial level switches are low cost, high performance switches made from highly durable plastics. Commonly used on restoration tanks for carpet cleaners, they feature a variable liquid differential and a single point pump up/pump down level control. Interchangeable differential band modules, for all non L-21+ versions, allow for 5 minute on-site switching of differentials.  The unit below has a 5″ differential and fits most Hydramaster and BLUEline models.  Other differential lengths and configurations available.  Please call or request a quote.
