PLC Controlled Dispensers (Pneumatic Shot Meter)

The AA4 dispenser allows for PLC volume and rate control without the added cost of a servo. These are used for critical applications where the volume is critical, volume confirmation is required, accurate rate control is required, or recipe volume control is required. 
AA4 dispensers are designed for dispensing UV cure materials and feature blackout covers to block light where the rod is exposed. 
Manufactured under US patent number 6,053,285.


 – Blackout covers protects against UV curing in the dispenser
 – Solvent cup protects against moisture curing in the dispense chamber
 – Patented air removal process ensures only airless material is dispensed into your manufacturing process
 – Provide accurate volume & dispense rate control through positive displacement
 – Flow-through design reduces the pack out of material
 – Provides PLC volume confirmation
