About this vaporizer

The PAX Flow from PAX Labs is the latest portable vaporizer from the Californian brand and relies on pure convection with a draw sensor. Instead of pressing a button, the device is simply activated by inhaling -- on-demand, with no waiting for a heat-up button. At just 90 grams, with USB-C charging and around 90 minutes of battery life, the Flow is aimed at users looking for a straightforward everyday vaporizer.

The temperature is controlled via 4 presets (182, 193, 204 and 215 °C). An LED ring and haptic feedback replace a display. PAX offers a 10-year warranty on the Flow -- a clear signal of durability. Current prices are available in the price comparison.

Convection Heating and Draw Sensor

The PAX Flow uses pure convection. Hot air passes through the herb in the stainless steel chamber instead of heating the chamber directly. The result: more even extraction and a clearer flavour profile than with conduction devices.

The draw sensor starts the heating automatically when you inhale on the mouthpiece – no button, no preheating. Heat-up time is around 20 seconds. Between draws, the heater switches off, which saves material. This on-demand principle fundamentally sets the Flow apart from older PAX models such as the PAX Plus or PAX 3, which used session-based conduction.

Anyone who prefers short individual draws benefits more from the convection principle than session users. The vapour tastes fresher and the plant material is used more evenly.

Research context: A study in the Journal of Pharmaceutical Sciences (Hazekamp et al., 2006) showed that vaporisation at controlled temperatures releases over 95 % of the desired active compounds, while combustion by-products are largely avoided. Source: PubMed 16637053

← Back to Overview
Does the PAX Flow have a button? +

No. The PAX Flow is draw-activated. You inhale on the mouthpiece and the convection heater starts automatically. The temperature level is changed by a short shake or via the app.

How quickly does the PAX Flow heat up? +

About 20 seconds. Since the heater starts with every draw (on-demand), there is no need for preheating in the traditional sense.

What temperatures does the PAX Flow offer? +

4 presets: 182, 193, 204 and 215 degrees C. There is no stepless adjustment, but the 4 levels cover the usual range well.

How long does the PAX Flow battery last? +

PAX states around 90 minutes of usage time. Depending on temperature and draw frequency, 8-12 sessions are possible. Charging is via USB-C.

What is the half-pack oven lid? +

An included lid that halves the chamber volume (from approx. 0,3 g to 0,15 g). Ideal for shorter sessions with less material.

Is there an app for the PAX Flow? +

Yes. The PAX App (iOS/Android, Bluetooth LE) shows the battery level, enables firmware updates and offers additional settings.

How long is the warranty on the PAX Flow? +

PAX provides a 10-year warranty -- much longer than for most portable vaporizers (typically 2-3 years).

Is the PAX Flow compatible with concentrates? +

The PAX Flow is primarily designed for dry herbs. There are separate PAX products for concentrates (the PAX Era series).
