integrated system consists of a
self contained preaction automatic sprinkler system
combined with a Nitrogen Generator, factory-assembled in
a single cabinet. All the components necessary for both
extinguishing systems are integrated.

components and the deluge
valve model F-1.
The Nitrogen generator is a
N
2
Blast
®
Type 1
FPS-250
or FPS-750 system, made by
South-Tek Systems.
The
N
2
Blast
®
FPS-250 and FPS-750 designed &
manufactured by South-Tek Systems provide an
economical, precise means of generating high purity
Nitrogen. Since air is comprised of ~79% N
2
we simply
and cost-effectively separate the N
2
from the air.
Nitrogen is an inert gas (non-combustible) and widely
used in thousands of industries along with Fire
Protection Systems. The N
2
is “generated” by means of
the air compressor pushing air into the simple, safe
membrane element, which in turn mechanically
separates N
2
molecules from other molecules found
within air.
The

cabinet is of the free-standing
type and is made of robust 14 gauge steel with a
rustproof fire red paint finish, polyester powder coated
and oven baked on a phosphate base. Each cabinet is
provided with two locked doors, reducing space
requirements for ease of installation and maintenance.
