Product Details
When cleaning coils, diluting your chemicals takes time and can leave the potential for user error – make the process easier with this Nu-Calgon 4774-0 coil cleaning gun! Capable of holding up to 2 quarts of cleaning chemicals, this spray gun makes cleaning as easy as filling the reservoir, attaching the desired wand, and setting it to the desired mix ratio setting; 3:1, 4:1, 6:1, 9:1, or 10:1. The chemical is diluted in the water automatically as you spray, removing the need for complicated calculations and conversions. While it is suitable for cleaning coils, this gun is also great for other applications where water-diluted chemicals are used too, such as wash rooms and food preparation areas. It has a recommended water pressure of 40 – 60 psi, though it will operate from 40 – 90 psi as well. The spray gun can be operated in three spray patterns. Use no nozzle for a solid stream that will carry up to 25′. The included deflector tip is excellent for covering large areas in a fan pattern, and the foaming wand is great for applications where extra foam is desirable. For added safety, the handle supplied with this gun also includes an anti-siphon to protect your water supply from accidental chemical contamination.
