This article provides an overview of older supported South-Tek N2-BLAST fire protection nitrogen generator models.
Legacy N2-BLAST systems are older South-Tek fire protection nitrogen generators that may still be supported for service, maintenance, and replacement parts guidance depending on the model and current parts availability. These systems were designed for fire protection applications and should not be confused with current-generation N2-BLAST models or South-Tek industrial nitrogen generators.
Legacy model families
Legacy fire protection systems may include the following models:
- FPS-650
- FPS-1250
- FPS-1750
- FPS-3000
- FPS-6000
- FPS-15000
- FPS-20000
What these systems were designed to do
Legacy N2-BLAST systems were designed to generate high-purity nitrogen for fire protection system supervision. These systems were used to introduce nitrogen into fire protection piping to help reduce internal corrosion and support system reliability.
Common legacy system characteristics
Depending on the model, legacy N2-BLAST systems may include features such as:
- Pressure Swing Adsorption (PSA) nitrogen generation
- Integrated or associated air compressor equipment
- Air filtration
- PLC-based or controller-based operation
- Nitrogen storage tank
- Automatic cut-in and cut-out operation
- Optional BlastOff leak detection features on certain models
Legacy manuals currently available
The following legacy manuals are currently available in this knowledge base:
- FPS-650 and FPS-1250 Legacy Manual
- FPS-1750, FPS-3000, and FPS-6000 Legacy Manual
- FPS-15000 and FPS-20000 Legacy Manual
