Xaar RackFit

Compact blade-format fluid management for high-viscosity applications

Why choose Xaar RackFit?

Maximise machine space

The slim blade-format design allows multiple units to be stacked side-by-side, creating a highly compact fluid management engine.

Enable high-viscosity jetting

With fluid heating up to 85°C, RackFit is designed to support demanding fluids and applications where viscosity control is critical.

Build flexible machine architectures

Control components can be mounted independently from the main tank, providing greater freedom when designing compact machine layouts.

Support specialist applications

Material options, fluid compatibility choices and software customisation allow RackFit to be tailored to specific fluids and industries.

High-temperature fluid management in a space-saving format

RackFit is a compact blade-style fluid management system designed for pressure-fed recirculating printheads. Its
rack-able architecture, high-temperature capability and flexible configuration make it ideal for machine builders developing compact, high-performance industrial printing systems.

Other Applications:
This printhead family can also be used to print fluids used in the Advanced Manufacturing and 3D market sectors. The piezo inkjet technology used in these printheads is capable of printing fluids with a range of viscosity, reactivity and conductivity. Xaar can support you in choosing the right printhead for the fluid type and for the application vs. the performance specification and price.
