HydroPulse® Low Flow Flat Fan Spray Nozzles
The new HydroPulse (HP) is a direct pressure spray nozzle with an air actuated shut-off designed to replace current Flat Fan installations where an intermittent spray is desired. It is a more compact, lower cost, and easier to maintain solution than competitor models.
Key Features of the HydroPulse Spray Nozzle:
- Simple and maintenance-friendly design allows for disassembly, inspection/cleaning, and reassembly with basic hand tools
- Internals can be removed in one simple operation!
- Can be rebuilt without uninstalling entire spray assembly
- Air Cylinders are not integrated and are easily replaceable
Design Features of the HydroPulse Spray Nozzle:
- Provides a controlled intermittent liquid spray using only liquid pressure as the force for atomization. Offers DRIP FREE performance.
- Interchangeable Flat Fan spray tips
- Pneumatically actuated for crisp on/off spray
- Straight through porting for fluid recirculation
- Variety of mounting brackets available
- Relatively coarse atomization
- Uniform distribution with tapered edges for use in overlapping sprays
