N2Blast: Mission-Critical Nitrogen™ Generators for Dry Fire Protection Systems
The N2Blast Corrosion Inhibiting System is designed to protect fire protection sprinkler systems from corrosion and extend system life. The N2Blast nitrogen generator introduces up to 98.5%+ pure nitrogen into the dry or pre-action fire protection system and displaces oxygen, a key contributor to the corrosion reaction, using the AutoPurge System. The N2Blast effectively inhibits Electrochemical, Galvanic and Microbiologically Influenced Corrosion (MIC), as well as sprinkler pipe ice plugs.
- Dual-bed, PSA (Pressure Swing Adsorption) technology
- Smart-Trak – Touchscreen control display; remote monitoring with mobile devices (select models)
- Install N2Blast with new sprinkler systems or retrofit an existing system to extend system life
- Manufactured in Wilmington, NC – generators are in-stock, ready to ship

N2 Blast Accessories
| 3-5 CS Series |
| 710 -CS Series |
| D-CS Series |
| J Series |
| Quick-Fill Compressor |
| AutoPurge 2 |
| AutoPurge 4 |
- Patented, calibrated orifice custom tunes to each individual riser based on its total capacity (gallons), minimizing runtime of N2Blast
- Purges FPS piping to ensure entire system is blanketed with 98%+ nitrogen purity
- No electrical required
- One AutoPurge is required per dry or pre-action system
| AutoPurge Timer - 1 Zone |

The Corrosion Triangle
Corrosion is a result of three elements coming together; unprotected metal, oxygen and water. Removing the presence of one element, in this case oxygen, disrupts the equation and inhibits corrosion.
UNPROTECTED METAL
Results in a uniform wall-thinning corrosion mechanism in black steel and localized pitting corrosion mechanism in galvanized steel.
OXYGEN ELECTROCHEMICAL POTENTIAL
There is an inexhaustible source of oxygen in compressed supervisory air.
WATER ELECTROLYTES
Comes from residual water and moisture left behind after hydro test.
Extend the Life of a Fire Protection System
Using 98% nitrogen instead of compressed air supervision significantly increases the service life of a fire protection system.
A long-term exposure test found that when comparing compressed air supervision to 98% nitrogen the life expectancy of new systems using black steel pipe increases from 20 years to 63 years, while systems using galvanized steel pipe increases from 10 years to 176 years.
