Design Changes
At a glance, the FLOW looks like a PAX—but it doesn’t work like one. The most noticeable change is the side-loading chamber, replacing the old bottom-mounted oven. This makes filling easier and reduces the mess when you’re on the go.
The airflow system has been reworked too. Instead of a long, narrow vapor path, the FLOW has a fully accessible air channel under a magnetic lid, making routine cleaning far simpler.
Physically, it’s small, lightweight (135g), and still pocket-friendly, staying true to the PAX reputation for discreet design.
Performance Upgrades
The FLOW is the first PAX to use hybrid heating, combining conduction to keep material consistently warm and convection for smooth, flavorful draws. This puts it in the same league as devices like the Solo 3 and Venty.
Notable improvements:
- Smarter heat management: A sensor monitors and adjusts temperature in real time, avoiding harsh hits or cool draws.
- Massive airflow boost: The new design moves four times more air than the last generation, cutting down draw resistance dramatically.
- Quick start: Around 35 seconds from cold to ready.
- LED “stealth mode” keeps things discreet in public settings.
Battery life sits at ~35 minutes of active vaping, with USB-C charging as standard and optional fast or wireless charging for convenience.
Ease of Use
Operating the Pax FLOW is simple:
- Choose from four heat settings (180°C to 215°C) or go to 225°C for water-pipe use.
- Load between 0.25g–0.5g of herb.
- Haptic feedback gives you status updates, while an accelerometer-based gesture system lets you check battery life with a quick shake.
Is It Worth Buying?
If you’ve loved PAX for its portability and low-profile design, the FLOW feels like the upgrade you’ve been waiting for. The new airflow, easier cleaning, and hybrid heating bring it closer to high-end session vaporizers while keeping the classic PAX simplicity.
At $350 (buy here), it’s an investment—but one that feels justified given how much it improves on its predecessors. Early stock is likely to be limited, so if you’re thinking about it, don’t wait too long.
