Heisenberg Circ Pre-Cooler 18.8mm

Heisenberg Circ Percolator Water Filter Attachment 18.8 mm

The Heisenberg Circ attachment for glass water filters features an 18.8 mm to 18.8 mm glass joint connection. The upper accessory connection is female, while the lower connection is male with an angled ground joint design. Thanks to its downward angle, this attachment is especially suitable for water filters with a side-mounted connection angle of approximately 40–45°.

With its compact water chamber and exposed joint design, this percolator attachment is compatible with a wide variety of beaker-style and standard glass water filters.

Reliable Cooling and Filtration with the Circ Percolator

The attachment is equipped with an integrated Circ percolator. This circular diffusion chamber inside the water section features 8 precision-cut slits around its lower edge. As air passes through the slits, it is evenly diffused and swirled through the water chamber, helping to improve filtration and create a smoother, cooler airflow experience.

The balanced airflow provides a comfortable draw while maintaining excellent diffusion performance.
