80g Vent‑Assist Desiccant Cartridge Description

The 80g Vent‑Assist Desiccant Cartridge is a precision‑vented moisture module engineered to extend the life and performance of your desiccant inside sealed storage containers, dry boxes, filament bins, and equipment cases.

Instead of exposing desiccant directly to sudden humidity spikes, this compact PC cartridge uses a controlled‑vent lid that allows moisture to enter gradually. This slow‑vent design helps your desiccant maintain stable, long‑duration drying performance, especially in environments that are opened frequently or experience small humidity fluctuations.

Drop it into any sealed container and it quietly maintains a consistent, ultra‑low‑humidity micro‑climate that protects 3D printing materials from moisture absorption, extrusion defects, and long‑term degradation.


Why Vent‑Assist Matters

Loose desiccant saturates quickly. Fast venting wastes capacity. UltraDry Vent‑Assist cartridges solve both problems.

By regulating airflow, these cartridges:

• Extend desiccant lifespan
• Reduce replacement cycles
• Improve humidity stability over time
• Support zeolite, silica gel, and all DryFusion™ media
• Deliver predictable, long‑term moisture control

This is moisture management engineered for makers who want set‑and‑forget reliability inside their storage workflow.


Specifications (3 Available Sizes)

  • 50g Cartridge — 100mm length × 30mm diameter

  • 80g Cartridge — 150mm length × 30mm diameter

  • 120g Cartridge — 91mm length × 47mm diameter


Part of the UltraDry™ System

UltraDry is a complete moisture‑control ecosystem built for 3D printing materials. Pairing UltraDry filament with UltraDry moisture products ensures:

• No wet‑filament extrusion
• No emergency heat‑drying cycles
• Consistent print quality across every spool
• Long‑term material stability and performance

The 80g Vent‑Assist Cartridge is the mid‑size option in the UltraDry lineup — ideal for medium storage bins, multi‑spool dry boxes, and equipment cases that need stable, long‑duration humidity control. Its extended length and controlled‑vent design make it the perfect balance of capacity and efficiency for everyday filament storage.

The DryFusion Advantage

DryFusion™ outperforms traditional desiccants by combining high‑capacity adsorption with a clean, dust‑free indicator system. The beads don’t just absorb moisture — they show you exactly when they’re spent, eliminating guesswork and protecting your materials with absolute consistency. It’s a smarter, more reliable approach to humidity control.

UltraDry™ PETG 3D Printing Filaments

UltraDry™ Moisture Control Desiccants are engineered to protect the materials that matter.
Whether you're storing filament, parts, tools, electronics, or sensitive components, UltraDry™ desiccants maintain a stable, low‑humidity environment that prevents moisture damage before it starts.

Moisture is the hidden enemy of polymers and precision materials — causing brittleness, surface defects, corrosion, and unpredictable performance. UltraDry™ desiccants eliminate that risk with industrial‑grade drying power designed for long‑term protection.

Why UltraDry™ Desiccants Deliver Better Protection

High‑capacity moisture absorption for extended life and stable humidity control
Fast‑acting drying media that begins working immediately
Durable, leak‑resistant packaging for clean, safe use in storage bins, drawers, and sealed containers
Optimized for filament storage, toolboxes, electronics cases, and long‑term material preservation
Maintains a dry environment for months, not days
Reusable options available (depending on SKU)

If you want consistent print quality, longer material life, and reliable storage conditions, UltraDry™ Desiccants are the foundation of a proper dry‑storage setup.

Moisture doesn’t just affect filament — it affects everything in your workspace. UltraDry™ desiccants give makers, engineers, and professionals a simple, powerful way to control humidity and protect their materials year‑round.

Material Safety & Compliance

UltraDry™ Moisture Control Desiccants fully comply with EU RoHS Directive 2011/65/EU + (EU) 2015/863. No restricted heavy metals, flame retardants, or phthalates were detected in any tested materials. Safe for use in sealed storage bins, filament containers, toolboxes, and long‑term dry‑storage environments.
