A NEW ERA OF OFFSET SMOKERS

ENGINEERED FOR PERFORMANCE

Meet the Fractal 90 — a custom offset smoker that packs serious punch into a more compact form. Built for enthusiasts who demand professional-grade results at home, this heavy gauge steel smoker delivers flawless consistency and flavour with every cook.

Precision-engineered to eliminate the common heat challenges of smaller pits, it’s the best backyard offset smoker for those who want pro-level performance without sacrificing space or mobility.

HEAVY-GAUGE MATERIALS

ZERO COMPROMISES

Crafted from industrial-grade 8mm and 10mm steel, the Fractal 90 is a smoker that doesn't flinch — even in extreme conditions. Its solid body ensures heat retention that cheap, mass-produced models simply can’t match.

This heavy gauge steel smoker is finished in a rust-resistant, polymerised linseed oil coating that won’t flake or peel like traditional paints. With stainless steel bolts and fixings throughout, this is a long-term investment in flavour, performance, and heritage. Over-engineered from every angle, it’s designed to outlive you.

DESIGNED FOR PITMASTERS

INTELLIGENT AIRFLOW

From deep smoke rings to unrivalled bark, the Fractal 90’s Dual-Flow system puts the power in your hands. Switch between reverse-flow and traditional offset airflow — or blend both — to suit your flavour profile and cut.

A common issue with smaller offsets is the reduced usable grill grate area caused by a combination of intense heat from the firebox and smaller air volume. The advanced airflow routing control makes this issue a thing of the past.

Engineered to maximise cooking surface, it delivers exceptional temperature balance and flavour control. This is smart airflow, reimagined for pitmasters for precise control without unnecessary complexity.

MORE HEAT, LESS FUEL

CERAMIC FIBRE INSULATION

With 2 inches of ceramic fibre insulation rated up to 2600°F, the Fractal 90 holds heat inside where it belongs. The insulated firebox reduces wood consumption, speeds up ignition, and keeps exterior surfaces safer to the touch — perfect for family-friendly backyard use. Unlike non-insulated models that radiate blistering external heat and rust over time, this smoker remains stable, efficient, and cooler on the outside.

BUILT TO PERFORM. BUILT TO ENDURE.

HEAVY DUTY COOKING GRATES

Tough 6mm carbon steel grates ensure reliable performance cook after cook, withstanding warping and providing maximum airflow. Whether you're searing, smoking, or slow-roasting, these pro-level grates handle it all without complaint and don’t degrade over time. Upgrade to 10mm stainless steel grates encased in laser-cut steel frames for even greater long-term durability and ease of maintenance.

NEXT-LEVEL HEAT CONTROL

XL FIREBOX & DUAL AIRFLOW

Heat distribution and airflow paths have been rigorously tested and optimised to the max, offering increased draw & airflow restriction – without increasing overall pit temperature.

The Fractal 90 features an extra-large firebox and firebox door for easy access to the fire. Optional Materia fire basket upgrades — made from 10mm steel — make live fire management easier than ever, helping extend the firebox life while making cleanout a breeze. It’s next-level fire control, made simple.

BUILT FOR LIFE'S ADVENTURES

EASY ROLLING. ROCK-SOLID STABILITY.

Designed with urban gardens and home patios in mind, the Fractal 90 includes ultra-heavy-duty 200mm castors with cast iron cores and soft rubber treads, rated to 1500kg. Lockable front swivel wheels offer precision placement, while fixed rear castors deliver stability. For a truly custom offset smoker experience, upgrade the rear wheels to the signature Circadian spoked design with 500mm steer rear wheels.
