Air Force Dryers


Natgraph manufacture a range of Air Force Dryers that has been developed from many years of experience gained in the design and production of over 700 Forced Air Conveyorised Systems, that are in use world-wide. These units have been designed, developed and manufactured for drying surface coatings applied to graphics, glass, medical products, textiles, automotive, electronics and aerospace etc, so no matter what the application, Natgraph have a solution. With 7 standard belt widths, Touch Screen PLC Control System, 4 layouts and modular design, this range of dryers is extremely adaptable and offers the versatility and efficiency that is required in today's production environments.

The Natgraph modular range of Air Force Dryers is available in 7 belt widths from 90cm through to 215cm, therefore an Air Force Dryer can be specified for all drying requirements. These can be from small print runs on Hand Printing Tables or medium length production runs printed on semi-automatic screenprinting machines, through to continuous high speed production on fully automatic cylinder presses.
The vital element in accelerated drying of solvent based inks is high velocity, high volume air delivered efficiently to the complete substrate area. Natgraph Air Force Dryers recirculate large volumes of air (over 15,000m /hour can be recirculated in each module, for special applications). Drying therefore takes place at lower temperatures resulting in economical operation and good substrate stability.
Air Force Dryers can be specified to be anything from a minimum of 3.5m long, depending upon the required production speed and the drying rate of the inks used. The final specification is best determined by carrying out drying trials in the Natgraph Nottingham based ‘Drying Solutions Centre’. These dryers require a three phase power supply.

Extended Inlets and Outlets
The inlet and the outlet of these dryers can be extended to enable the dryer to operate with more than one printing machine, or allow extra time for ‘ink flow’. These extensions are in multiples of 0.5m, or 1m sections and can be fitted with vacuum hold-down systems.
Power Supply Socket Outlets
Electrical power supply socket outlets can be fitted at each end of the dryers, these are intended to provide an electrical supply for the printing machine and Stacker or Vibrating Collection Tray. This facility means that only one cable needs to be provided to supply the complete printing line, thus saving on installation costs.
CCTV Stack Monitoring System
A colour CCTV system can be fitted to all Natgraph dryers, this system includes a freestanding, mast mounted camera above the stacker and a dedicated TV monitor mounted on a fully adjustable stand above the inlet of the dryer. This allows the operator to see the stacker without leaving the printing machine, which is very important when operating long, high speed, fully automatic printing lines.

Layout & Paint Finish
Air Force Dryers can be manufactured in any layout to suit the intended location or printing machine, with controls and ducting on either side. This can result in significant space saving. Natgraph also have the ability to finish these units in industry standard machine colours, so that the dryer will match existing print lines, or a customer’s house colours.
