Fume Hoods
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, 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.
Polypropylene hoods are nonconductive. They’re also translucent, so they let in more light than polyethylene hoods for added visibility.
Polycarbonate hoods are dent and scratch resistant. They’re also clear, offering an unobstructed view from all sides.

Bench-Top Air Cleaner Hoods
Filtering away dust and particles, these hoods create a clean space for demanding work, such as bioprocessing, pharmaceuticals, electronics, and optics. They have a HEPA H14 filter to catch 99.995% of particles down to 0.1 microns, as well as a pre-filter to pull out large particles before they reach the HEPA filter. To draw air from outside the hood into the filters, they have a fan; there’s no need to connect them to ductwork. A flow monitor tracks the airflow and alerts you with a visible and audible alarm if the fan fails. They meet Fed. Std. Class 100 and ISO Class 5 clean room requirements.
As an alternative to filtering the air of an entire room, these hoods leave a large enough opening for comfortable access inside and have internal fluorescent lighting to help you see your work. Their work surface is 304L stainless steel, which resists bacteria and chemicals, and also is easy to clean. Mount them on workbenches and carts that are designed to hold them, or place them on your own bench top.
