Flat fan nozzles stand for uniform liquid and distribution. Particularly high energy jets are generated with spray angles up to 60°.

Nozzles with small flow rates are especially suited for humidifying and spraying in general. The flow geometry of the nozzle allows to produce accurate, compact jets, available with different distribution patterns.

Basically, flat fan nozzles are designed for parabolic liquid distribution. Unaffected by transient pressures, they are suited for universal application. Their performance data are exactly defined. Operational values, such as flow rates, spray width, jet thickness and liquid distribution are readily available for a great variety of feed pressures. There are also special-design nozzles with rectangular or trapezoidal distribution of liquid.

Simple and cost-saving fixing attachments, as for instance dove-tail guides and eyelet clamps, considerably facilitate assembling and aligning of the nozzles.

For all cleaning operations, in steelmaking and in many other fields of surface treatment, in short, wherever powerful, uniform water jets are required, flat fan nozzles constitute a decisive basis for achieving reliable process results.

The tongue-type nozzle design represents a special kind of flat fan nozzle With this nozzle type, the flat fan spray pattern is produced by a solid stream, impinging upon and deflecting from an outside deflector plate. As a result, a powerful, sharply delimited flat jet is shaped. The deflector plate has the form of a tongue, which determines the spray angle formation. Due to large free cross-sections, tongue-type nozzles are particularly clog-proof.

Application overview

• air curtains
• blowing off and out
• cleaning
• cooling
• drying
• reheating
• transporting

As a rule, any flat fan or solid stream nozzle can be operated with air instead of liquid. However, you'll obtain the best results using the nozzle designs we specially engineered for applications of compressed air or saturated steam. For further details, please refer to the next pages.
In addition to air, various nozzle types are also suited for injecting saturated steam. Typical applications of air nozzles are, for instance, efficient blowing off and blowing out, cooling, drying or cleaning.

Whisperblast^® multi-channel air nozzles

Where uncontrolled compressed air is applied, very often annoying, high-frequency hiss noises arise, which may cause serious harm to hearing. These "noises" are produced by turbulences generated at the air outlet. Their intensity depends on the shape of the nozzle orifice and on the air pressure. This means: the better and stronger the air jet is supposed to be, the higher the health-injuring noise level and the higher the air consumption and its cost.

The solution: multi-channel air nozzle
featuring a significantly reduced soand level, high blowing power and low air consumption.
The performance of multi-channel air nozzles is based on partitioning the air inflow into single air jets. 16 air channels, arranged to ensure optimum flow conditions, provide for a particularly uniform, straight and powerful overall air jet.

In comparison to single-hole air nozzles the advantages are as follows:

• Reduction of the noise level of up to 12 dB
• Low service air pressure with the same blowing power
• Lower air consumption
• Better blowing effect over a long reach
• Lower operating costs
