AirLess Resin Bubble Remover Machine review: bubble-free resin test

In this AirLess Resin Bubble Remover Machine review, I test how well this device removes air bubbles from epoxy resin. In my test with letsresin resin, you can clearly see the before-and-after effect.

My hands-on test

I mixed epoxy in a measuring cup, placed it inside the AirLess Resin Bubble Remover Machine, and followed the process step by step. With thicker resin (especially at lower temperature), degassing clearly takes longer.

Important tip for thicker resin

letsresin resin is more viscous and often needs extra time.
At lower temperatures, resin gets even thicker.
Light pre-warming helps bubbles rise faster.
After degassing, let it rest briefly before pouring.

I have an older version of the Resiners bubble remover.

Comparison: 2 Resiners versions

Model	Best for	Strengths	Watch-outs
Cheapest version	Small batches, jewelry, beginners	Compact, fast setup, lower entry price	Smaller volume, often longer cycle needed for thick resin
More expensive version	Frequent use, higher output, larger batches	Larger capacity, more efficient workflow	Higher purchase cost

Comparison with other brands

Brand/type	Pros	Cons
Resiners (Lite/Pro)	User-friendly, compact, fast for resin cups	More closed ecosystem, less flexible for large atypical batches
Let’s Resin (AirZero / Upgraded Resin Bubble Remover) Germany \| Belgium	Digital timer, compact machine, fits hobby workflows	Outside peak periods, delivery timing may vary by country
VEVOR chamber + separate pump	Often lower cost per liter, many sizes	More parts, louder, setup is more leak-sensitive
Classic metal vacuum chamber kits	Robust and scalable	Heavier, less compact, less plug-and-play

Pros and cons from my use

Pros

Quick visible effect on larger bubbles.
Compact footprint on the workbench.
Easy to include in a regular workflow.

Cons

Thick/cold resin needs more time.
Microbubbles may need an extra cycle.
Good pouring technique still matters.

My final verdict

Positive: compact, simple, and visibly effective on many bubbles.
Critical note: slower results with thicker resin.
Important: this is not a pressure pot like VEVOR; technique and expectations differ.
