Description
xThe Nu-Calgon 4774-0 Coil Gun Sprayer is a durable 2-quart dilution and foaming sprayer with five adjustable mix ratios and a quick-disconnect hose nozzle for fast, reliable coil and surface cleaning.
Designed for HVAC technicians, janitorial teams, and facility maintenance pros, this coil gun blends concentrated cleaners with water and produces a controlled foam or fan spray for targeted cleaning. Built to resist chemicals and everyday wear, the sprayer pairs a capacious 2-quart bottle with a foam wand and a quick connect that speeds setup and teardown on the job.
How does the adjustable dilution system work for different jobs?
The 4774-0 has five preset mix ratios—3:1, 4:1, 6:1, 9:1 and 10:1—so you can meter concentrated cleaning chemical to water without separate measuring tools. Switch settings depending on soil level, chemical strength and material compatibility to conserve product and control performance.
- Five clearly marked mix settings for quick switching
- Eliminates the need for separate measuring cups
- Suitable for both heavy-duty and light-duty cleaning tasks
What spray patterns and application features does it offer?
The included foam wand and deflector tip allow you to choose between thick foam for dwell time and a fan spray for rinsing or broader coverage. The trigger design gives precise control, while the deflector spreads the spray evenly across coils or surfaces.
- Foam wand enhances chemical contact and cling
- Deflector tip produces an even fan pattern for rinsing
- Trigger control lets you start and stop without waste
Is this sprayer durable and easy to service in the field?
Manufactured for rugged use, the sprayer resists common environmental exposures and typical cleaning chemicals. The quick-disconnect hose nozzle speeds hose removal, reducing downtime, and the 2-quart bottle is sized for portable convenience while delivering enough capacity for multiple applications.
- Chemical-resistant materials for longer life in harsh conditions
- Quick-disconnect fitting for fast hose changes and transport
- 2-quart capacity balances refill frequency with portability
Who is this for?
