Fume Control for a Variety of Processes. The 40” Wide Ducted Fume Hood, often identified as an exterior-ducting exhaust hood, is a very popular model among laboratories, pharmacies, manufacturing facilities, research & development departments, and a variety of additional environments that require a hooded enclosure for their current or new fan and ducting system. The thoughtful design of these systems ensures that it is suitable for standard 24” deep countertops. Ducted Fume Hoods are typically used during applications where filtration media may not be effective because of the volume of materials used or filter incompatibility. Typical uses include:

Solvent Vapor Control
Epoxy Fume Extraction
Powder & Capsule Filling Processes
Light Acid Etching Processes
Volatile Organic Use
Asbestos Particulate Control

High-Quality Materials.The standard materials used for this hood include a high-density polyethylene base, acrylic sides, and clear polycarbonate top and front lid. These materials were selected for their chemical and corrosion resistance, impact resistance, and customizable nature.
