BF Micro™ Applicator:

• Integrated needle and self-cleaning nozzle virtually eliminate adhesive stringing and downtime. (Optima module)
• Adjustable needle stroke sets adhesive flow for extreme accuracy. (Micro module)
• Standard air open/air close module for accurate bead placement.
• Platinum sensor provides optimum temperature control.
• Water resistant standard.
• Reliability-Air open/air close standard gives clean, sharp cutoff every time.
• Simplicity-Small design makes installation in hard-to-reach places easier.
• PerformanceBuilt-in, heated filter maintains a cleaner nozzle orifice.
  

  Air Open/Air Close Design

  Over time, adhesive applicator modules that use an air open/ spring close system can lose spring tension, resulting in stringing and poor cutoffs. The BF Micro™ applicator module is designed to operate as an air open/air close system that does not rely on a spring to close the orifice during operation. The result is both cleaner cutoffs and better general operation over a longer operating lifespan. While this feature may be optional on competitive modules, only ITW Dynatec offers this feature standard on the BF Micro™ adhesive applicator.
  
  

  Each applicator features a Micro module with a replaceable nozzle mounted to a single service block. The module also has an adjustable needle stroke to set adhesive flow for extreme accuracy. The Micro module is designed for high speed/high pressure (above 400 psi) applications where a sharp cutoff is necessary.

  Each module operates with air pressure opening and closing the orifice. Standard air open/air close functionality reduces stringing and gives a clean, sharp cutoff every time throughout the life of the head, unlike spring-operated applicators which cause more stringing as the spring wears and loses tension.

  High performance seals (which are also standard) improve applicator life, while the platinum sensor allows for better temperature control over conventional temperature control sensors.
