High-flow capability and small-micron filtration make this the perfect unit for cooling tower cleaning: filtering wastewater and returning clean, reusable water to your tower basin. When used in conjunction with the CTV-1501 Cooling Tower Vacuum, this powerful cleaning tandem provides you with an advanced, integrated system that is designed specifically to restore optimal operating conditions to cooling towers. Twin filter cartridges clean tower water down to 5 microns for better performance. The filters are easy to clean and reuse. A clean water discharge rate of up to 50 GPM means it can handle any heavy-duty tower-cleaning job you encounter.
