GRISUN Stainless Steel Charcoal Whirlpool Insert for 22" Kettles — 304 SS, Heat-Focusing Funnel

GRISUN Stainless Steel BBQ Whirlpool is a 304-grade charcoal funnel insert designed to concentrate heat, extend burn time and improve searing performance in 22" and larger kettle-style grills.

This stainless-steel whirlpool insert drops into Weber Kettle 22.5/26.5 models and other 22"+ charcoal grills to focus airflow, raise internal temperatures, and promote more efficient charcoal combustion. Made from non-magnetic 304 stainless steel, the unit resists corrosion and warping while simplifying cleanup. It’s a single-piece accessory intended to help you get hotter sears, longer burn windows, and more consistent heat distribution without modifying the grill.

How does the GRISUN whirlpool improve charcoal efficiency?

The funnel shape channels air and concentrates charcoal in a tight column so coals reach higher temperatures with less fuel. By creating a centralized combustion zone the whirlpool reduces wasted heat at the grill walls and helps maintain steady internal heat for longer periods.

• Funnel top diameter: 8"; bottom diameter: 12"; height: 4" — fits 22"+ kettles.
• Requires only a half-filled column of charcoal for high heat searing.
• Promotes faster ignite times and extended burn duration.
• Cut fuel use while reaching temperatures up to around 600°F under typical conditions.

Will this fit my Weber Kettle or Kamado grill?

The GRISUN whirlpool is sized for 22-inch and larger kettle-style and kamado-style grills, including Weber 22.5/26.5 models, Smokey Mountain, Summit, Big Green Egg XL, and Kamado Joe Big Joe. Always compare the funnel’s dimensions to your grill’s internal diameter and grate clearance before buying.

• Check inside diameter and grate height for clearance above the funnel.
• Fits most 22" kettles and larger kamados when installed on the charcoal grate.
• Not intended for small tabletop grills or gas-only models.

What performance changes should I expect when cooking?

You’ll notice quicker searing times, more intense radiant heat near the food, and longer continuous burn time per load of charcoal. The whirlpool concentrates heat under the cooking zone, which lets you sear steaks fast and maintain roasts at stable temperatures for longer smokes.

• Improved searing performance and faster crust formation on meats.
• Reduced need to refill charcoal during medium-length cooks.
• Enables four cooking styles: low-and-slow smoking, high-heat direct cooking, searing, and radiant heat grilling.

How durable and easy to maintain is this stainless-steel insert?

Manufactured from 19GA (0.04") 304 stainless steel, the whirlpool resists rust and warping from repeated high-heat use. Its smooth stainless surface wipes clean and stands up to acidic drippings better than cheaper alloys.

• 304 stainless steel — non-magnetic and corrosion resistant.
• Will not chip, warp, or rust like low-grade metals.
• Simple to brush or rinse clean after use; oven-safe temperatures.

Who is this for: The GRISUN Stainless Steel BBQ Whirlpool suits backyard grillers who own a 22" or larger kettle or kamado and want hotter searing, longer charcoal life, and more consistent heat without changing fuel type or grill hardware. It’s ideal for home cooks who sear steaks, roast poultry, or want flexible cooking modes (sear, direct, radiant, and low-and-slow) while keeping cleanup straightforward.
