The most commonly used metals that CKV hoods are manufactured from are Stainless Steel, and Aluminized Steel. 304 Stainless Steel for Canopy Hood Streivor's standard is to build the hood canopy using high quality 304 Grade Stainless Steel. 304 Stainless Steel is a non-magnetic alloy that has lower carbon to minimize carbide precipitation [...]

CKV hoods are manufactured form several type of stainless steel, The most commonly used material are 304 and 430 stainless steel. Type 304 stainless steel is a high grade of stainless steel that includes a minimum of 8% nickel. Type 430 stainless steel is a lower grade of stainless steel that includes a minimum of [...]

The benefit of using type #304 verses #430 stainless steel is that the #304 is better suited for the harsh environment that a Type I CKV must withstand. The 304 material will better withstand the harsh degreasers and other chemical that are used during the hood and duct cleaning, the chemicals that make up [...]

Aluminized steel is steel that is coated with aluminum during the milling process. Aluminized Steel Characteristics Aluminized steel was developed for providing more structural durability and a high yield strength in highly corrosive environments. Aluminized steel is carbon steel coated, through the hot-dip process, with an aluminum-silicon alloy. This process assures a tight metallurgical bond between the steel sheet and [...]

Aluminized metal can be used in the non-exposed portions of a CKV hood, such as the exhaust plenum. When it is imperative to reduce the costs of the CKV hood, substituting aluminized metal in the non-exposed portions of the hood can be a consideration.

National mechanical and fire codes generally allow balancing dampers to be installed in CKV hoods and ducts under the condition that the dampers are listed and installed in accordance with their listing. Streivor's BalanceAire is a UL 710 Listed Restaurant Hood Balancing Damper. Read More

The two most common types of balancing dampers for type I CKV hoods are opposed blade dampers and guillotine dampers. Streivor's Balancing Dampers are UL 710 Listed for Type I Restaurant Hoods

An opposed blade is a damper that has two or more blades that are fixed with the damper housing in an opposed position relative to each other. The blades are adjustable. By moving one or more of the blades the resistance created by the blades on the air passing through the damper can be increased [...]

The advantage of using an opposed blade damper verses a guillotine damper, is that a guillotine damper is designed to create resistance to the air flowing through the duct by sliding a blade into the duct opening, usually from one side. This type of dampering will cause un even air flows through he duct [...]
