Profile: Recreation Supply Co., Inc. deals with filtration products, heaters, lights and pumps & strainers. Some of our filtration products include cartridge filters, cartridge washers, D.E. filters and sand filters. The Blaster 1000™ automatic filter cleaner automatically rotates the filter, which results in the blasting of dirt and debris from the filter. The IntelliFlo VS+SVRS pump has a safety vacuum release system (SVRS) which provides an important layer of entrapment protection. It includes a built-in controller with proprietary software that detects blockage and automatically shuts itself off within seconds.
