Pneumatic Panel Sprayers

Pneumatic Panel Sprayers

Our fully pneumatic Panel Sprayers have been developed in association with major coating manufacturers, subsequently we can offer a wide range of options from which to customise for individual requirements.

Consistency - The sprayers remove the variations in consistency that is experienced when using hand held guns, thus offering a means to set optimum, repeatable conditions to achieve consistent results.

Consistency in coating application is absolutely essential for subsequent evaluation of colour, gloss, opacity and general appearance, also physical properties including thickness, sagging, levelling and adhesion.

Evaluation of these properties is particularly important when applying high performance coatings such as metallic, pearlescent paints and specialist effect coatings.

Setting parameters - The sprayers offer the means to set the atomisation, coating build, flash off timing, flow/levelling, film thickness, gun traverse speeds and accelerated drying, these settings are particularly important when defining the characteristics of new formulations.

Optimum settings - Once the optimum settings for a product have been achieved they can be easily reproduced for quality control for further sampling, thus enabling identification of any inconsistences in formulation or preparation.

Single or twin gun operation gun changeover, flash-off timing can be selected and panel lift increments can be set from to 40 to 70mm.

Two additional panels are supplied, one each side of the control panel for the addition of options and accessories.

Electrostatic spraying

We can offer the facility for the fitting of Electrostatic Spray Guns, to our Panel Sprayers, contact our Customer Services and your gun supplier before finalising requirements for this type of system.

International standards - ASTM D823/A

Additional optional equipment

Remote Gun Setting: This feature enables the operator to control atomisation and fan width of pneumatically adjusted spray guns via a remote unit (can be supplied with all models).

We would be pleased to advise on any special requirements for models in our range, please contact Customer Services for further information.
