Overview

This document provides comprehensive technical information on flat fan nozzles, covering specifications, design features, materials, applications, and critical operational parameters. These nozzles are widely used for spraying, cleaning, cooling, and dispersion tasks across various industries.

1. Specifications and Performance Data

Flat fan nozzles are available with spray angles ranging from 0° to 110°, including standard and made-to-order angles. Capacity codes from 1 to 100 correspond to increasing flow rates measured at pressures between 0.5 and 15.0 kgf/cm². Flow rates are provided for thread sizes 1/8, 1/4, and 3/8 inches, expressed in liters per minute or equivalent units. Key parameters include average particle size (in micrometers), minimum free passage diameter (in millimeters), and recommended filter mesh sizes to prevent clogging.

2. Design and Features

• Fan-type spray with a single line and tapered edges, producing a bell curve flow distribution with reduced intensity at edges.
• Standard single-piece construction; multi-piece quick-install designs are available for easier maintenance.
• Customizable spray angles between 0° and 110°, with specific angles available upon request.

3. Materials and Construction

• Metal options include Stainless Steel 303, Stainless Steel 316, Brass, and Hardened Stainless Steel (HSS) for high-pressure use (up to 200 kgf/cm²).
• Polypropylene (PP) is offered for lower pressure applications.
• Material choice influences recommended working pressure, flowrate tolerance (±5% for metals, ±10% for PP), and spray angle tolerance.
• Typical recommended working pressure is 3.0 kgf/cm².

4. Applications

• Cleaning: Vehicles, containers, filters, dust, gravel, metals, machinery, steel plates, high-pressure cleaning, wet processing, display panels, and machine tools.
• Cooling: Gases, tanks, machinery, metals, and roofs.
• Dispersion: Humidification, chemical spraying (etching solutions, lubricants, insect repellents), fire suppression water screens, dust control, and deodorization.

5. Ordering Information and Notes

• Orders must specify thread size and type, nozzle series, capacity code, spray angle, and material.
• Standard pressure data are highlighted in red within tables.
• Appearance and dimensions vary by model and material; customers should request detailed specifications.
• Pressure unit conversions (MPa, bar, psi) and additional technical details are available on the manufacturer's website (LORRIC.com).

6. Dimensional Data and Weight

7. Critical Parameters and Limitations

• Recommended working pressure is generally 3.0 kgf/cm²; deviations may impact performance and durability.
• Flowrate tolerance: ±5% for metal nozzles, ±10% for plastic nozzles at recommended pressure.
• Spray angle tolerance: ±5° for metal nozzles, ±10° for plastic nozzles.
• Jet angle tolerance: ±3° for all nozzle types.
• High-pressure applications require HSS material to withstand pressures up to 200 kgf/cm².
• Minimum free passage and filter mesh sizes must be adhered to avoid clogging and maintain spray quality.

8. Additional Technical Data

Performance data tables include flow rates at various pressures and nozzle sizes, with some data points marked as unavailable. Pressure units are primarily in kgf/cm², with conversions available online. Operating temperature considerations (up to 110°C) are noted, emphasizing the need to match nozzle selection to environmental conditions.

Summary

This document serves as a detailed reference for selecting and applying flat fan nozzles. It highlights the importance of choosing the correct nozzle size, material, spray angle, and operating pressure to optimize performance for cleaning, cooling, and dispersion tasks. Customization options and adherence to recommended parameters ensure durability and effectiveness across diverse industrial applications.
