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. 

As of May 2, 2022, we are transitioning all of our Corsair Arches to include the Stainless Steel Upgrade. This feature is loved not only for its aesthetic beauty, but most important for its durability. Stainless steel resists rust and is extremely resilient in intense heat. It is guaranteed to outlive galvanized steel.

The Stainless Steel upgrade applies to the Corsair Arch Sides, Base Stack and Stack Pipe as called out in the photo below.

Insulating the Arch

See our Brick and Insulation support pages for more information about brick configurations. We also offer a support guide for Brick Batter (High Temp Mortar).

Please note: The Corsair air-tight firebox door will come pre-insulated for you. The ceramic blanket, firebrick and mortar which required to insulate/protect the remainder of the arch is sold separately.

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.

1 review for Corsair Evaporator w/Raised Flue Pan Set, Standard Config – Customize It!

  1. Patrick Diamond

    I figure it’s about time I can write a review of this wonderful evaporator. First off make sure you have lots of good dry wood cut to wrist size pieces to get this rig going. You will boil between 45 and 55 gallons of sap per hour staying constant on the fire. I have been using this evaporator now for 6 years. In that time, I have had no issues with anything other than normal items you would need to replace such as rail gasket, stiffened gasket, etc… The quality of the workmanship in the pans is amazing. One year I got very sick, and the pans sat all year until next spring. When I was able to get out and look at them I figured they were ruined. I took them out pressure washed them, brought them in the house and with only hot water they were as good as new. You basically only have to set your auto-draw off for each day, crack the valve, make sure all the other valves are open, all your pumps are working, collect sap, start the fire, feed the fire, until you are done. It just runs itself. I will never look at any other brand of evaporator as long as this team of people is in business. If You want the best for yourself buy Smoky Lake Maple Products. That is what it Boils Down Too.
