Honeywell Xtralis FAAST FLEX FLX-020

FAAST FLEX Product Guide FAASTFLEX
Piping Design "U" Pipe - Single Channel (FLX-010):
U-pipe network, Class C with In-line filter
Exhaust pipe of 5m (E), T-junction 10m (T), Branch of 30m (B1), First hole at 5m (F), 6 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 5m ≤ 14 m
T T-junction position 10 ≤ 10 m (15m-E)
B1 Branch length 30m
PL Pipe length with low speed
with high aspirator speed
5+10+30=45m ≤ 45 m
≤ 65 m
N Number of holes 6 See Table
S1 = L1 / ( Number of holes – 1 ) = 25 / 5 = 5 m (≥2.5m)
± 0.2*5m = ±1m
