The Katalyzer Weha from Katalyzer is a log-style desktop vaporizer with pure convection heating and a glass vapor path. The cylindrical wooden housing contains a ceramic heating element that warms air -- when you draw, hot air flows through a glass bowl loaded with herbs. The Weha belongs to the log vaporizer family, prized for efficiency and simplicity.

Katalyzer manufactures its devices in small batches. With 3 shops in the price comparison, the Weha is available across Europe.

Log Design: Compact and Efficient

Log vaporizers are cylindrical desktop units that stay plugged in continuously and are ready to use at any moment. The Katalyzer Weha follows this principle: power on, let it heat, attach a glass stem loaded with herbs when needed, and draw. No session timers or auto-shutoff.

The Weha's wooden housing measures only about 12 cm tall and takes up minimal desk space. This compact footprint is typical of log vaporizers -- they are the smallest desktop devices on the market. Despite the small size, the Weha delivers dense, flavorful vapor.

Log vaporizer efficiency is remarkable: on-demand convection only extracts as much material as needed per draw. This conserves herbs compared to session devices that heat material continuously over several minutes.

Convection with Glass Vapor Path

The Weha uses pure convection: a ceramic heating element inside the wooden cylinder heats air. When you draw, hot air flows through an attached glass stem containing the herb material. The material is heated exclusively by hot air -- no contact with hot surfaces.

The vapor path is glass and ceramic. The glass stem can connect to a water pipe with a suitable adapter. Various glass attachments are available as accessories -- from straight stems to curved ones to water pipe adapters.

Temperature is set via an analog dial on the device. No digital display -- adjustment is by feel and experience. Lower settings deliver terpene-rich vapor, higher settings produce denser clouds.

Craftsmanship: Wood and Handwork

The Weha's housing is turned from solid hardwood. The wood species varies by availability -- walnut, cherry, or oak are typical. Each unit is unique with individual grain patterns. Craftsmanship is at a high level.

Inside sits a ceramic heating element powered by a mains adapter. The cable is permanently attached. Heating output reaches estimated 170-220 C depending on the dial position.

In the box: Weha log vaporizer, one glass stem, screens, and power adapter. Additional glass attachments and replacement screens are available as accessories.
