About the XERO DI Tank

Water fed window cleaning in soft water areas has been made simple with the lightweight and compact XERO DI Tank.

XERO DI Tanks are proudly made in the USA by our team with durable brass fittings that fasten to your hoses securely. Equipped with the XERO 3/4" Pure Garden Hose to Female Swivel Adapter, a Garden Hose Male x 3/4" NPT male, and XERO virgin resin, this tank will be ready to clean as soon as it reaches your doorstep.

Once your TDS meter reads higher than usual, these tanks can be refilled with new resin, so you can keep using them for your work. They are designed to be used standing upright to work properly.

The 1/2 cubic foot tank is 8.5 inches x 21.5 inches and its total capacity is 4 gallons of purified water.

These tanks are economical, easy to use, and built to last. They're perfect for areas with soft water or for the window cleaner just beginning their water-fed journey.
