Evenfan Nozzle

Evenfan nozzles are available in an 80° spray angle, which produces a narrow rectangular spray pattern. Rated at 3 bar pressure, these nozzles produce an even distribution across the full swath width.

Features

• Precision moulded in polyacetal, a highly stable polymeric material with outstanding wear characteristics
• High level of quality control throught the manufacturing process ensures consistent compliance with specification
• Colour coded (in accordance with ISO/DIS 10625) for quick indentification of flow rate
• Compatible with most standard nozzle caps
• BCPC (British Crop Protection Council) coded to assist with correct nozzle selection

Description
This nozzle is available in an 80° spray angle, which produces a narrow rectangular spray pattern. Rated at 3 bar pressure, these nozzles produce an even distribution across the full swath width.

Applications
This nozzle is generally used in the single mode with crop sprayers and planter mounted sprayers for inter-row and over-row banding application of treatments such as pre and post emergent herbicides. It is particularly suitable for single nozzle applications with knapsack sprayers where reduced dosing at the edge of the band can be avoided. Even fan nozzles are also used in vector control programmes for use with compression sprayers to apply residual insecticide to walls and flat surfaces in buildings for mosquito control.

Installation - Crop Sprayers: To ensure the required band width is achieved, the boom or planter/cultivator nozzle height must be carefully adjusted in relation to the target and for the nozzle spacing used on the boom.

Installation - Knapsack Sprayer :To ensure the desired swath width is achieved, the nozzle must be maintained at a constant height as indicated in the Evenfan application rates - Imperial - Metric - USA. A suitable chain or weighted cord attached to the lance behind the nozzle, and adjusted in length to just contact the target with the nozzle at the appropriate height, will help in maintaining a constant height when spraying. Ensure that any preset pressure regulator fitted to the knapsack sprayer or hand lance is set for the correct pressure operation before commencing to spray. Always read the operating instructions of the equipment manufacturer.

Standard nozzles are available in two spray angles of  80° and 110°, producing a narrow elliptical spray pattern. Rated at 3 bar presure, these nozzles individually produce a triangular (normal) shaped distribution but when boom mounted at 0.5m spacing provide 50% overlap to give an overall even distribution.

Features

• Precision moulded in polyacetal, a highly stable polymeric material with outstanding wear characteristics
• High level of quality control throughout the manufacturing process ensures consistent compliance with specification
• Colour coded (in accordance with ISO/DIS 10625) for quick identification of flow rate
• Compatible with most standard nozzle caps
• BCPC (British Crop Protection Council) coded to assist with correct nozzle selection

Applications

The Standard nozzles are used for broadcast applications of pre and post emergent herbicides, fungicides and insecticides. They are often used with knapsack sprayers where the nozzles are used in conjunction with a 2, 3 or 4 nozzle boom fitted to the hand lance, reducing the application time. Although best suited to multi nozzle applications, flat fan nozzles are also widely used in vector control programmes for use with compression sprayers to apply residual insecticides to walls and flat surfaces in buildings for mosquito control.

Installation - Crop Sprayer

To ensure uniform target coverage the boom height must be correctly adjusted in relation to the target and for the nozzle spacing used on the boom. The figures shown below will provide a 50% overlap ensuring an overall even distribution. Note that the height is measured from the nozzle to the target, whether it be soil or vegetation.Always take into account the height of the vegetation.
Ideally the nozzles should be offset by approximately 5° to the boom in order to minimise interference between the spray patterns and to avoid droplets coalescing between the nozzle and the target. Most standard nozzle holders offset the spray by 5°. Check for evenness of spray distribution at target level under the boom. This is best achieved by spraying out water onto dry concrete and watching it dry out. If it tends to dry in stripes then this indicates that the boom is possibly too low. Adjust boom height and repeat until water dries evenly.
It is always better to set the boom height slightly above rather than below the figures stated, since under field conditions boom bounce can dramatically alter the nozzle height. However it is wise to avoid excessive boom heights since this will increase potential spray drift.

Installation - Knapsack Sprayer

To ensure the desired swath width is achieved, the boom must be maintained at a constant height as indicated in the Standard Nozzles application rates metric and imperial. A suitable chain or weighted cord attached to the boom between nozzles and adjusted in length to just contact the target with the nozzle at the appropriate height, will help in maintaining a constant height when spraying. Ideally the nozzles should be offset by approximately 5° to the boom in order to minimise interference between the spray patterns and to avoid the droplets coalescing between the nozzle and the target. Ensure that any preset pressure regulator fitted to the knapsack sprayer or hand lance is set for the correct pressure operation before commencing to spray.

The Twin Fan Standard design comprises twin 110º standard flat fans which sprays 30º forwards and 30º backwards relative to the direction of travel to provide a double angle of attack for improved penetration.

This nozzle is suitable for slender vertical targets such as black grass, wild oats, etc and blight control

• Twin fans provide good coverage, improved penetration and spray deposition
• Provide smaller droplets at higher volumes
• Do not require a double cap-this nozzle fits into existing caps
• Polyacetal construction for chemical stability and excellent wear characteristics
• ISO colours
