The Dilution at Hand Extreme has a sleek design and enhanced color scheme that provides a modern appearance in any housekeeping environment. The dual station has a 4 chemical or dilution dial-a-blend for bottle filling and 1 product for bucket filling. The 1 gallon per minute (4L / min.) bottle fill has 1 hand activation for easy spray bottle filling and a built in1 gpm flow disk that improves dilution accuracy compared to other dispensing systems. The 4 gallon per minute (15L / min.) high flow is great for filling buckets, scrubbers and other larger containers and is operated by a lock-on button on the dispenser or at the point of use with remote fill option. Available as the dispenser alone (830GAP) and with 4 locking enclosures in either 1 gallon (5L) or 2 liter (1/2 gallon) sizes (830GAP-QIG, 830GAP-Q2L). The remote fill is optional on all 3 dispensers. Uses Dema’s ASSE 1055B approved action gap backflow preventer or optional air gap backflow protection (substitute AG for GAP in part#).
