Pair these hoods with an exhaust system to contain harmful fumes, vapors, and gasses while venting them away from work spaces—they protect users from inhaling or coming in contact with them. To access the enclosed space, these hoods have an adjustable sliding window or cutout, which also lets your exhaust system pull air from the outside. Polycarbonate windows are more durable than acrylic windows. All of these hoods resist chemicals and corrosion.

Polyethylene hoods have a molded one-piece construction with rounded inside corners to prevent gaps and crevices, making them easy to wipe clean. Those with a fixed observation window are good for demonstrations and when working in groups because they let others view contents and processes from the other side. The observation window is made of polycarbonate to withstand dents and scratches.

Polycarbonate hoods are dent and scratch resistant. They’re also clear, offering an unobstructed view from all sides.
