FAAST FLEX Product Guide FAASTFLEX
Piping Design "U" pipe - Dual Channel (FLX-020):
FLX-020 U-pipe network, Class C with In-line filter
Without Exhaust pipe (E), T-junction 1m (T), Branch of 40m (B1), First hole at 20m (F), 6 holes
Example:
Required Rules
N Number of holes 6 See Table
E Exhaust pipe 0m See Table row C
T T-junction position 1m See Table row A
PL Pipe length with
high aspirator speed
40+1+0=41m ≤ 65 m
L1 Last hole position, Branch 1 41-1-20=20m
1. Verification of project constraints and determination of aspirator speed
2. Calculate nominal step between holes and hole position deviation form nominal
3. Determination of necessary Sensitivity Level
and the hole diameters
S1 = L1 / ( Number of holes – 1 ) = 20 / 5 = 4 m (≥2.5m)
± 0.2*4m = ±0.8m
