Introduction: Pneumatic atomizing nozzles are versatile tools used for atomizing viscous liquids, cooling, gas cooling, humidification, lubrication, and web dampening. They come in various designs to meet specific spray and flow requirements.

Designs and Principles: These nozzles operate on principles such as self-aspiration (siphon principle), gravity, and pressure. They can mix fluids inside or outside the nozzle and offer spray patterns like full cone or flat fan.

Adjustability and Control: Liquid flow and droplet size can be manually adjusted. Automatic or intermittent operations are possible with pneumatically controlled pistons or magnetic valves.

Technical Details: The document provides detailed specifications for various series of nozzles, including spray angles, liquid and air pressure requirements, and flow rates. It also includes ordering information and accessories for specific series.

Overview: This document provides technical specifications and applications for pneumatic atomizing nozzles, specifically the Series 140, which operate on the siphon principle with internal mixing. These nozzles are used for lubrication, cooling, and humidification of air.

Specifications: The nozzles have a spray angle of 20°-30° and are identified by the ordering number 140.252.30.01. They are designed to handle both liquid and air, with specific measurements for aspiration height and air pressure. The narrowest free cross-section for water is indicated as 'E'.

Performance Parameters: The document provides detailed performance data, including liquid and air flow rates at various pressures (0.5, 1.0, 2.0, 3.0 bar). The weight of the brass nozzle is 70 grams.

Components and Accessories: The nozzle assembly includes a brass nipple (014.010.30.04) weighing 17 grams and a gasket (014.040.72) with dimensions 7.8 x 12 x 1 (EWP 210).

Assembly Scheme: An assembly scheme is provided, indicating the flow of air and water through the nozzle system.
