Nu-calgon 47740 Coil Gun Sprayer Quick Connect 2 Quart

Product Description

The NU-CALGON 47740 is a hose-end coil gun sprayer designed for applying water-diluted chemical solutions in HVAC and commercial cleaning applications. It features a quick-disconnect hose connection and accepts a standard 2-quart capacity bottle, making it well suited for HVAC technicians and facility maintenance professionals who need controlled, repeatable chemical delivery. The sprayer ships with a foam wand to improve foaming action on coil surfaces and a deflector tip to fan the spray pattern across fins and coil faces. Five selectable mix ratio settings allow the technician to dial in the correct dilution without measuring separately.

This sprayer is intended for coil cleaning tasks on residential and light commercial HVAC equipment, including condenser and evaporator coils. It is also suitable for use in food preparation areas, wash rooms, and any environment where water-diluted chemical application is required. The quick-disconnect feature allows fast hose changes between jobs, and the foam wand attachment helps cleaning solutions dwell on vertical coil surfaces longer for improved soil removal.
