Freemax Silus



Freemax is a manufacturer based in China that is relatively new in the vaping world. They have great staff, many with solid credentials from other well known manufacturers. This is the first Freemax product we review, and look forward to many many more.

The Freemax Silus look is not really ground breaking ... it's awfully difficult to come up with something unique in clearomizers without crossing the threshold into "vase" looking devices. However, Freemax has taken the look to a good level. The outer shell is chrome and looks great with the E LVT that I tested it with, matching the beauty ring on the E LVT exactly. Inside, it is stainless steel all the way with silicone seals and O rings.

Every aspect of the Freemax Silus is quality:

  • Stainless steel drip tip
  • Pyrex Glass tank with 3.5 ml capacity
  • Huge coil
  • Adjustable Air Flow with huge dual holes
  • Buttery Smooth Threads
  • Buttery Smooth Air Flow adjustment
  • Top or Bottom fill

It is well engineered and well constructed. Even the drip tip was shipped with a silicone cover. Packaging is just as well thought out ... the Freemax Silus is wrapped in thick foam and packaged in a box.

The Freemax Silus is 21 mm in diameter (0.83 in.). Without the drip tip, the height is 51 mm (2.0 in). With the drip tip, it is 71.5 mm (2.81 in.). There is a knurled portion at the top and a knurled portion for the air flow adjustment ring.

The drip tip is quite nice. It is stainless steel with large air flow and sits firmly at the top. A silicone seal keeps it there firmly. The air flow hole and control ring oval opening are very large – this is good news to lung vapers that are looking for a convenient clearomizer for "on the road" vaping.  The air flow control ring is limited in movement ... the movement will expose the entire hole, it can also be completely closed. I tried it at the completely closed setting, there is still a bit of air flow getting through. I am glad to see that it does not close completely. Quite frankly, I can't figure out why anyone would ever want to shut down air flow for any reason.

The Freemax Silus that I received included a 1.5 ohm coil and was ready to use right out of the box. I cleaned it and added my favorite eLiquid (a spearmint/peppermint juice of my own making). An ohm check showed it as 1.6 ohms ... I had to check on a second device and it is 1.6 ohms. The bottom portion of the Freemax Silus is completely sealed, there is no possibility of eLiquid leaking into the battery from this clearomizer. The coil is unique, it is not compatible with any other known device. This is a BDC (Bottom Dual Coil).

Spare coils are packaged in blister packs. They are available as single units or in packages of five.

The Freemax Silus is still not widely available yet, but kit pricing MSRP is US $28. That would include the Freemax Silus clearomizer, a spare coil, and one cone/adapter. That's nearly half the price of an Aerotank. I've tested the Aerotank (actually, the Aerotank, the Aerotank Mini, and Aerotank Mega) and this Freemax Silus is every bit as good and may be better in air flow.

The Freemax Silus is a surprise find ... and I am glad I found it. The best flavor rendition from my Spearmint/Peppermint eLiquid has always been a rebuildable atomizer (Kayfun 3.1) ... the Aerotank is close, but not quite there. The Freemax Silus is there. Not only does it transfer flavor exceptionally well, it also generates very good vapor. There are no instructions included with the Freemax Silus. In taking it apart, I discovered that it can be filled from the top or bottom ... top loading is the preferred method and my "ideal".

At the top of clearomizers are the Aerotank and Nautilus. They are now joined by the Freemax. I would easily pick the Freemax overall, though. The price point gives it the edge. None of these tanks have any leaking or gurgling, all three are easy to fill with the Freemax Silus having a considerable edge since it can be top loaded.

Through this article, I am going to make one recommendation to Freemax. Freemax, you have an excellent tank here, it is well engineered and well built. There are several areas, if improved, would propel the Silus to become the bar at which all others would be compared to. At the top of the clearomizer, you have a knurled grip area to assist in separating the top filler cap from the glass portion. The bottom of the tank where the glass sits needs to be knurled. In practice, when separating the bottom coil base from the glass tank portion, it was very difficult to grasp. Every time I did it, the portion that ended up unscrewing was the glass tank separating from the top metal part. Other than that, you have as close to the perfect clearomizer as possible.

So what's the verdict? Is this worth it? I heartily recommend this clearomizer. When I tested the Aerotank, I was thoroughly impressed with the flavor rendition and air flow control. The Freemax Silus kicks this up a notch (maybe two) and at a dramatically lower price. The Freemax Silus is not widely available yet, but I plan on getting a few more. To all my vendor friends: if you want to see a copy of this and contact information for Freemax, let me know. I will be glad to share this information and help vapers get ahold of one or two of these.

Update: My thanks to Bill who private messages me on Facebook. My apologies, I should have been clearer on the coil ... it is a Bottom Dual Coil.
