Premium, Stainless Steel Divided Pan

The handcrafted, mirror finish stainless steel pan is the same premium quality that we are known for. We use high grade 22ga stainless steel which enables more efficient heat transfer from the fire to the sap compared to our competitor’s thicker stainless steel. Two continuous flow dividers are formed into the structure of the pan, NOT tacked into place as an afterthought. The pan profile includes full-length handles which offers easy maneuverability and increased strength. A thermometer port with 3″ dial thermometer and a stainless steel draw-off valve are also included.

Corsair Arch

This revolutionary evaporator design is fully convertible from conventional draft to forced draft in an instant. The airtight front gives you a critical advantage in efficiency and performance whether you’re running the forced air kit or if you choose to keep things simple with natural aspiration. 

The large loading door nicely compliments the large combustion chamber. This air-tight door will help prevent cold air from being pulled along the bottom of pan, negatively effecting evaporation rate and efficiency. 

The Corsair arch is fully steel framed. The entire perimeter is built as strong as possible, giving you confidence when filling the pans above it with your precious liquid and igniting an intense fire inside it. Additionally, the arch fits the geometry of whatever pan set you plan to use on it, forcing the pan to take full advantage of the heat created within. The nice, big firebox is 24″wide x 32″tall x 25.5″deep.

Insulating the Arch

You will need 20 thick bricks and 20 thin bricks (for the firebox) and 1 case of ceramic insulation blanket (for the rest of the arch and behind the bricks). See our Brick and Insulation Kit for more information.

Please note: fire brick/ceramic blanket not included.

Four Reasons the Door Design is Critical

1Competitor doors/fireboxes are often much too small. In contrast, the 16″ x 16″ Corsair doorway makes it easier to load wood, and generate more heat.

2If you ever want to upgrade to Forced Draft — either now or in the future — you need an airtight door. With Corsair, you’re all set.

Regardless whether you have Forced Draft or Natural Draft, an airtight door increases efficiency. A leaky door works against you by allowing cold air to enter the firebox and cool your pans.

4Our competitors’ cast iron door fronts have been cracking since the 1800s. The Smoky Lake Corsair door will not. We guarantee it.

Compare the Durability

Forced Draft Kit Option

Forced Draft Kit includes domed gratesBENEFITS:

  • Much higher evaporation rate compared to natural draft.
  • Easier to burn larger/unseasoned wood. This means you won’t have to cut your firewood as fine and you can burn wood that is less perfect.
  • Increased agility. You will be able to shut down your evaporator much faster because it allows firewood to burn quicker and more completely.


The forced draft option includes upgraded domed cast iron grates and an electric blower. If ordered at this time, the blower will come pre-mounted to the arch. Otherwise, if you order the arch as conventional draft, the back of the Corsair firebox will include a perforated knock out and mounting studs to accommodate a forced air kit in the future. If the time comes when you need more performance, just remove the knock out, mount the blower and replace the steel grates with the kit’s new perforated, domed cast iron grates.
