This is compatible with CoolZoneUSA industrial-strength portable systems (e.g.: WorkZone, ComercialZone, SportsZone).
First stage filter for Extreme series pumps. Two stages are necessary for proper filtration—a 10-micron fist stage and a 5-micron seconds stage. Change as needed. Overly dirty filters will prevent a pump from moving enough water to run correctly and may cause damage to the pump.
