F23 - Siphon/Gravity-Fed Spray Set-ups, External Mix, 1/8J
and 1/4J Series
Features and Benefits
- For round and flat sprays, angle “A” is maintained throughout distance “B”. Beyond “B”, the spray becomes turbulent and will project out to distance “D”.
- When using a siphon or gravity-fed liquid system, the liquid is supplied by either a liquid siphon or a gravity-feed.
- Designed to draw liquid through the feed line into the air flow where it is atomized.
Air Caps
Round spray and flat spray air caps produce
round spray and flat spray patterns.
1158 retainer ring and 3612 gasket must be ordered
separately from the spray set-up, but are included in
the standard nozzle assembly. Please contact your
sales engineer.
Refer to page F3 for Siphon/Gravity-Fed Spray Set-ups diagram.
