Honeywell Xtralis FAAST FLEX FLX-020

FAAST FLEX Product Guide FAASTFLEX
Piping Design "I" pipe - Single Channel (FLX-010):
I-pipe network, Class C with In-line filter
Exhaust pipe of 10m (E), First hole at 20m (F), Last hole at 40m from the first hole (L), 9 holes
2. Calculate nominal step between holes and hole position deviation form nominal
1. Verification of project constraints and determination of aspirator speed
3. Determination of necessary Sensitivity Level and the hole diameters
Required Rules
E Exhaust pipe 10m ≤ 29 m
F First hole 20m 1 ÷ 30m-E
L Last hole 40m
PL Pipe length with low speed
with high aspirator speed
10+20+40=70m ≤ 50 m
≤ 80 m
N Number of holes 9 See Table
S = L / ( Number of holes – 1 ) = 40 / 8 = 5 m (≥2.5m)–
± 0.2*5m = ±1m
