Purpose-Built Fire Suppression for Prusa & Desktop 3D Printer Enclosures
The BlazeCut TR032FK-PRUSA is a compact, automatic fire suppression unit designed specifically for small, enclosed spaces like 3D printer enclosures. Tailored for use with Prusa models and similarly sized desktop printers, this self-contained system provides fast, mess-free fire protection—no wiring, external power, or manual activation required.
The system consists of a black, abrasion-resistant detection tube filled with FK-5-1-12, a Clean Fire Suppressing Agent. When the temperature inside the enclosure reaches approximately 267°F (±6°F), the tube melts at the hottest point, forming a nozzle that releases the agent directly at the source of the fire. The result is instant, targeted suppression that won’t damage your printer, electronics, or surrounding space.
Because it operates silently and without residue, the TR032FK-PRUSA is ideal for workspaces, studios, classrooms, and any area where enclosed additive manufacturing takes place. It installs directly into your 3D printer enclosure and is completely maintenance-free.
🔒 This model does not include a pressure switch. For advanced features like alarm signaling or system-triggered shutdowns, see BlazeCut “-S” models (e.g., TR025FK-S).
