ST - Straight Throw
WS - Widespread Throw
Data relating to the tabulated ‘throw’ dimension is based on ‘free jet’ horizontal discharge of air at
isothermal condition to a terminal velocity of 0.25m/sec.
MULTIPLE UNITS
In applications where multiple adjacent jets are used, then the throw lengths are increased as
follows:
2 jets: 1.40 x throw length
3 jets: 1.70 x throw length
4 jets: 1.90 x throw length
