Small cyclone burner for brazing and soft soldering on the Sievert Promatic system. The rotating flame gives the most efficient, even and all-round heat transfer to the pipe. Brazing to 15mm pipe diameter (up to 720°C). Soft soldering to 28mm pipe diameter (up to 400°C). 2.1kW at 2 bar, 170g/h, 14mm burner, 120mm neck tube at 30°. Fits the Sievert 3366 Promatic handle. Handle sold separately.
Key Features & Benefits
Cyclone Rotating Flame — The most efficient Promatic burner type for brazing and soft soldering. The rotating flame wraps around the pipe for even, all-round heat transfer without moving the torch.
Brazing to 15mm Pipe (up to 720°C) — The primary application for cyclone burners — efficient, even heat for copper pipe brazing joints.
Soft Soldering to 28mm Pipe (up to 400°C) — Can also be used for soft soldering applications where the cyclone flame is preferred over a brush flame.
2.1kW Output at 2 Bar — Low, controlled output directed efficiently by the cyclone flame pattern.
170g/h Gas Consumption — Very economical for a brazing burner.
14mm Burner Diameter — Compact for tight access brazing and small-pipe work.
120mm Neck Tube at 30° — Angled for comfortable positioning at the joint.
Stainless Steel & Brass Construction — 179g, 275mm total length.
Twist 'N' Lock Fitting — Instant, tool-free connection to the Sievert 3366 Promatic handle.
Ideal For
Brazing copper pipe up to 15mm diameter
Soft soldering up to 28mm pipe diameter
Plumbers & heating engineers doing continuous brazing work
Tight access brazing positions requiring a compact burner head
The cyclone flame for efficient, all-round brazing on small pipe. Sievert 3366 Promatic handle sold separately. Also available: the 3335 medium cyclone burner for brazing up to 22mm pipe.
