We are a UK supplier of the HVT Sai TAF (top air flow) atomizer, designed for use with concentrates, which is well known for it's versatility, excellent construction and lifetime warranty. It's rated highly by ourselves and others for very good reasons! Available in stainless steel, black (SS) or titanium, milled to perfection, with a 510 connection, no moving, flimsy or breakable parts (the coils themselves, like all coils, can be damaged) with the right setup this atomizer can produce more vapour than you'll know what to do with! This is considered an intermediate level vape as it does have removable coils which need to be handled and cleaned with care when taken out of the atomizer. It has a leakproof design. Our number one recommended product that should be used with the Sai TAF buckets is the new top air flow tube upgrade, we've included a link to the demonstration video on the product page and now send this out as standard with every atomizer. We advise lubricating your o-rings with a little o-ring lubricant applied with a finger tip to stop them becoming sticky.
Aside from a huge range of available coils the Sai TAF also has a wide range of airflow options from restricted to completely free flowing. One of the other advantages of the top airflow atomizer is the ability to use any of the coils, top or bottom airflow, as it's compatible with both! We recommend using the 22mm heat sink or V2 24mm heat sink to protect your mod box from getting warm when using the titanium bucket.
The HVT Sai TAF comes with the original titanium bucket (pre installed with donut coil) we also stock a variety of coils including the twisted 4mm kanthal/black ceramic or quartz rod coil (wattage mode only) - one our favourites and in our opinion the beastiest coil out there! If you purchase the HVT Sai with a Poseidon V2 water attachment you can have 10% off that, just enter "makeitsmooth". Aside from it's main purpose of filtering and cooling vapour the Poseidon V2 improves the airflow in the bucket due to the intake tube sitting slightly higher up, this reduces the amount of material pushed up the side increasing efficiency. This allows the bucket to be loaded with smaller or larger dabs! To change coils simply unscrew the old and replace with the new! We've made a quick demonstration video on how to replace these.
We apologise, shopify store only allows one code to be entered per order, so we advise using the one that saves you the most!!
Because of higher production costs the Titanium Sai Atomizer variation is £10 more, but is 30 grams lighter (82g and 52g respectively) with the titanium bucket installed. The titanium atomizers also retain less heat so the mouthpiece and body stay cooler during use.
The Sai TAF titanium bucket is also especially effective when used with terp balls (Ruby or Silicone Carbide). These help to spread and mix the material providing smoother vapour and more even vapourization throughout a session, they also help retain more heat inside the bucket improving the effectiveness of the vapourizer, especially with increased air flow. These are great when used alone or a number are preheated in the bucket.
We also have in stock the Sai TAF glass mouthpiece which stays much cooler than the metal ones. This is great for longer sessions. We also have available an o-ring which can be placed around the mouthpiece allowing the atomizer to be simply used with 18mm water tools by seating them on the o-ring. We've found a very effective setup is the upgraded airflow tube and 18mm Triple Percolating Hydratube Bubbler.
Atomizer o-rings should be lubricated with a small amount of vegetable oil, coconut oil, o-ring lubricant or similar to avoid them becoming sticky.
Smooth and creamy vapour is produced by the titanium bucket when using temperature control and the twisted 4mm kanthal wrapped quartz/black ceramic rod coils can be used to slowly vapourize your material or can be turned up to 23w (max recommended setting for a balance of vapour production and aroma, they go higher) and blast it off!
Titanium Bucket Donut Coil: HVT recommended setting are 24-28W with TC-Ni, 380-450F or 193-232C - popular settings also include 30w on Ni or with a TCR value between 260-315 depending on your mod box, start at the lower end and work up if you're having trouble with Ni temp control. Small variations in how the coil contacts the base of the bucket will also affect how it heats up. The most accurate way to keep temperatures stable is by calibrating the TCR to the ceramic coil temperature without the bucket on, this way the temperature will never rise above the temperature set on your mod box. This works well with the Sai because the bucket usually have such good contact with the ceramic heating coil. The TCR value for the coil is around 260. With this TCR value the bucket will stabilise around 10 Celcius lower than the temperature of the coil during general use, so the temperature can just be set around 10C higher than needed! Left to heat up over an extended period the bucket will eventually stabilise a few degrees cooler than the coil but this takes some time as the bucket is in contact with the base of the Sai which acts as a heat sink and during use air is being drawn over it. These heat up times will also depend on the wattage your box is set at. TCR settings vary slightly between mod boxes.
For more information on how to set up you atomizer with custom TCR settings check out our blog post.
If you have a preferred coil type we don't currently stock just pop us a message and we'll get them in our next order so we have them available for you.
The Sai is excellent when used with terp balls as these help to mix and spread the material around the hot edges and corners while preventing it from being pushed too far up the sides by the airflow. This also improves the flavour and efficiency of the atomizer. Use the standard rocking/swirling motion to keep them on the move!

In the Box
- Sai TAF Atomizer in Stainless Steel, Black or Titanium (ROHS certified materials)
- 8.8mm (W) x 12mm (H) (internal dimensions) bucket.
- Dab Tool
- Airflow options
Please note all coils eventually need replacing however all the coils we stock are reliable and tend to last for many months with care and proper use. If used outside stated specifications they will be more likely to fail unexpectedly, do not use them outside specification. The air flow in bottom air flow coils (BAF) eventually block, at this point you can switch to top airflow on your atomizer! Coils/crucibles/buckets should be cleaned with a burn off cycle then wiped before use to remove any oils left over from manufacture. This can be done at full temperature (300-315 Celcius) on your mod box with temp control coils and for kanthal coils on wattage mode at the maximum recommended wattage. It's never a bad idea to give your atomizer a quick clean before use too.
Planet of the vapes have had full material analyses done of the Sai and Sai coils. All materials were shown to be of high quality. You can view these results here.
The Poseidon V2 water attachment pictured is not included but is available separately.
This Atomizer/Diffuser requires a regulated mod box capable of sub ohm vaping.
