For every demand, there's an advanced filter solution

To make every drop of water and dollar count, Culligan Engineers recommend filters with Progressive Flow technology. This reliable feature allows your Culligan system to be sized to your exact needs - allowing for smaller systems to be used where high demand is periodic. For larger systems, Progressive Flow technology brings filters online and offline based on need, for increased cost-efficiency.

Businesses requiring consistent water quality use Culligan Smart Controllers and Progressive Flow technologies. These combined features utilize a series of sensors to monitor water treatment quality and performance. By constantly measuring quality and demand, your custom system can be appropriately and efficiently sized for your process needs, saving money upfront and in long-term maintenance.

*Peak (15 gpm/ft2 - 37 m3/hr/m2) - Very good quality effluent at specified flow. Increased pressure loss. Recommended for suspended solids loads < 300 ppm.
