Description

- Finely atomized, hollow cone spray without compressed air - Very small drops often achieving misting performance - Ideal for use in dust control and humidification applications - Wall-mount options for installation on room walls, vessel bulkheads or pipeline - Orifice inserts, cores and strainers are easily removed for inspection or cleaning - Most models can be supplied with an internal strainer - Spray angles: 155° to 156° - Uniform spray distribution from 2.8 to 5.7 gph (11.2 to 22 lph) - Operating pressures from 20 to 80 psi (1.5 to 6 bar) **Flow:** The liquid passes through slots in the core component. The slots make the liquid spin in a circle at a very high speed. The energy from the spinning action causes the liquid to break up into very small droplets and form a hollow cone pattern as it exits the orifice.
