Retaining Ring—

The brawn of the AirFree dispensing technology

The multi-legged stainless steel design locks the syringe in place, making the syringe and gun one. In dispensing, any flexing between the barrel reservoir and surface to which it is secured represents a pressure loss and will change the amount of fluid dispensed. Due to the tight tolerance between the stainless steel retaining ring and the gun, there is no room for barrel flexing when the thrust-of-dispense cycle is applied. This is a key contributor to maintaining positive displacement dispensing.

The Control Unit—

The brains of AirFree dispensing

The control unit gives the user control over volume output; dispense rate, reverse motion and motion delay. By imputing and manipulating these parameters, the microprocessor will calculate the number of steps needed to achieve the requested result. A universal switching power supply automatically adapts to multiple AC inputs. The foot pedal may be removed for automated activation using a dry contact.

Helpful Hints

Priming the System

Removal of the tip cap and introduction of a new needle traps air pockets inside the stem of the syringe and hub of the needle. Because our system positively displaces fluid, it is very important no air is present in any portion of the syringe. Therefore, it is important that any trapped air is pushed out of the syringe prior to dispensing.

Changing Barrels Reservoirs

Same Size Barrels: Simply switch one barrel for the next. The only consideration is to prime the new dispense tip prior to dispensing (page ?). The LDS9000 recognizes barrels of the same size so it is not necessary to reset the system.

Different Size Barrels: When changing to a different size barrel, it is necessary to reset the lead screw, reset the dispense parameters and prime the dispense tip. To reset the lead screw remove the barrel reservoir, flip the Auto/Manual switch to Manual and the Extend/Retract switch to Retract. Hold the foot pedal down until the lead screw retracts all the way into the dispense gun.
