Fishman LDS9000 The heart of AirFree dispensing, The precision of AirFree dispensing technology

DefiningtheSystem

Manual Mode

Program is ideally suited for priming the dispense tip and manual dispensing such as potting and beads. In manual mode the parameters and function of the parameters are exactly the same as program mode. The only difference is that the system will only dispense fluid for the amount of time the user holds the foot pedal down.

The Linear Drive System

AirFree PosiLokTM Piston—

The heart of AirFree dispensing

This unique design has made positive displacement with a barrel reservoir possible. Re-engineering the pneumatic piston concept, the high interference fit of the piston and the luer lock connection with the Linear Drive System enables intelligent dispensing. By increasing the interference between the O.D. of the piston and the I.D. of the barrel, we are able to completely seal the chamber eliminating material leakage. The luer lock connection provides complete control over forward and reverse motion. The intelligent control unit microprocessor knows the barrel I.D., the distance traveled forward and the distance traveled backward. With every dispense cycle the piston moves the exact distance every time, guaranteed. Drip-free dispensing, air pocket venting and all-plastic component dispensing are maintained with the new design.

The Dispense Gun—

The precision of AirFree dispensing technology

The motor used inside the dispense gun is a linear actuator. The linear actuator creates forward motion by rotating nut between electrically charged poles. The drive screw runs through the nut located at the center of the motor. The design of the plastic gun housing captures the top of the drive screw preventing it from rotation. When electrically charged, the center nut will step from one magnetic pole to the other, moving the drive screw forward. It is important to note that the drive screw not rotating allows the attachment of the PosiLokTM piston, creating the linear motion critical to positive displacement. By reversing the charge, we are able to create reverse motion.

LDAV one electrical pulse (motor step) = .0005"

MDAV one electrical pulse (motor step) = .00025"

SDAV one electrical pulse (motor step) = .000125"
