Efficient powder spraying

WEKO-Powder-Application-Systems (WPA) such as the series of WEKO-AP, are based on modular system concepts. They have been designed specifically for the preparation of a powder-air mixture and an accurately reproducible and extremely uniform powder application. At the same time, the WEKO-AP systems work very efficiently.

This is how it works

Powder is applied to the material web with exactness thanks to the Precision Metering System PMS. A uniform air flow transports the powder to the nozzles while the control unit calculates and monitors the function of the system; it also adapts the amount of powder to the respective format and the machine speed. The special nozzle geometry allows for very high transfer efficiency of the individual powder particles and, consequently, less powder consumption and less dust development in the environment. Even extreme settings can be made with the Pre-Select Function.

The right system for any machine

All WEKO-AP systems are designed for simple and straightforward operability:

  • AP100 Series: For small and medium-format machines, including 3-level Pre-Select function, speed adjustment, powder monitoring, central format adjustment
  • Series AP200 and AP300: Medium to large-format machines, including precise PMS metering system, infinitely variable Pre-Select function, semi-automatic format adjustment, automatic speed adjustment, simple, quick powder change (VARIOBOX®)
  • AP500 Series: For high-speed range, large format, maximum transmission frequency, absolutely uniform minimum powder consumption
  • AP900 Series: Industrial powder spraying, high speed absolutely uniform application with repeat-accuracy, large storage tank, individual customization
