When “Mist Quality” Matters More Than Spray Coverage

Flat fan nozzles are chosen for directional cleaning. Hollow cone nozzles are selected when the real requirement is atomization quality — how your spray behaves in the air, on surfaces, and inside chambers.

Ideally Suited For:

A uniform ring-shaped cone spray
Fine droplet distribution for surface contact
Stable atomization across varying pressure ranges
Better results in wetting, cooling, scrubbing, and gas conditioning

What Is a Hollow Cone Nozzle?

A hollow cone nozzle produces a circular, ring-shaped spray pattern. The spray forms a cone with minimal liquid at the center, creating strong perimeter wetting and efficient distribution.

Swirl Chamber Precision Critical for rotation and atomization

Orifice Geometry Defines flow rate and impact

Surface Finish Ensures stable fluid dynamics

“Small parts with big fluid dynamics.”

Performance Engineering

Custom Hollow Cone Nozzles — Tuned for Your Process

We don’t sell off-the-shelf nozzle catalogs. We manufacture made-to-order hollow cone nozzles based on your operating conditions.

Customize Parameters

Spray cone angle (30° / 60° / 90°+)
Target droplet size range
Flow rate at specific pressure
Anti-clogging design features
Compact or reinforced bodies

Ideal Applications

Chemical wetting & scrubbing
Dust suppression / humidification
Cooling and gas conditioning
Tank washing & reactor spraying
Defoaming / chemical dosing

DFM Included

Share your application goal and constraints — we’ll convert it into a manufacturable nozzle geometry with Design for Manufacturability input.

Common Problems Buyers Face — and How We Solve Them

Atomization is inconsistent across batches

Cause: swirl chamber deviation or orifice shift

Our approach: controlled CNC process, geometry repeatability, inspection checkpoints

Nozzles clog too often

Cause: narrow passages or poor internal flow transitions

Our approach: optimized internal transitions, anti-clog structure options

Cone angle changes as pressure changes

Cause: unstable internal energy conversion

Our approach: performance-driven geometry tuning for your operating range

Chemical corrosion destroys nozzle

Cause: wrong material choice (or wrong sealing material)

Our approach: corrosion mapping → SS316 / ceramics / engineered plastics

Result: stable cone shape, predictable droplet behavior, and lower downtime.

Material Options for Hollow Cone Nozzles

Choose materials based on chemical resistance, wear life, and operating temperature.

Stainless Steel

316 / 303

Balanced corrosion resistance & mechanical stability. Best for general industrial lines.

Brass

Cost-effective

For non-aggressive liquids. Best for standard wetting or rinsing processes.

Plastics

PP / Nylon

Strong chemical compatibility. Best for dosing lines and corrosive environments.

Ceramic

Zirconia

Outstanding corrosion & temp resistance. Best for aggressive chemicals.

Tungsten Carbide

Inserts

Extreme wear resistance. Best for slurry and particle-laden fluids.

Frequently Asked Questions

What is the difference between a hollow cone and a full cone nozzle?

A hollow cone creates a ring-shaped cone spray with less liquid in the center, while a full cone distributes liquid more evenly throughout the cone volume. Hollow cone is often used for fine wetting and scrubbing.

Are hollow cone nozzles good for atomization?

Yes. Many hollow cone designs use swirl motion to improve atomization and create finer droplets, depending on pressure and geometry.

How do I reduce clogging in a hollow cone nozzle?

Options include optimizing internal flow transitions, increasing passage robustness, choosing suitable filtration, and selecting materials that resist scaling or corrosion.

Can you make a hollow cone nozzle that fits my existing system thread?

Yes. We can match NPT, BSPT, or custom thread and sealing requirements.

Can you customize droplet size for my process?

We can tune geometry toward your atomization goal, and recommend a working pressure range to help achieve stable droplet behavior.

Do you support prototypes and production orders?

Yes. Rapidaccu supports prototyping, small-batch verification, and stable production scaling.
