Chemicals can eat away at most metal duct, but not this PVC system. It’s often used to exhaust corrosive gases, vapors, and fumes. Components press-fit together and secure with PVC pipe cement.

Rain Caps

Prevent blockages that can disrupt airflow in vertical duct and exhaust stacks. These caps keep water and debris from entering your system.

Keep your hair out of the way to prevent stray hairs from contaminating food.

Bouffant—Bouffant hair covers cover your entire head. For short- to medium-length hair, use those with a 20" to 21" stretched diameter; for longer or thicker hair, choose a 24" stretched diameter.

Kleenguard Polypropylene Fabric—Kleenguard polypropylene fabric is made of five layers of nonwoven fabric, so it is harder to tear than Tyvek polyethylene. It holds up to occasional contact with nonhazardous liquids, such as water and paint spray.

Polyethylene/Tyvek Fabric—Polyethylene/Tyvek fabric holds up to occasional contact with nonhazardous liquids, such as water and paint spray. It is made of heat- and pressure-bonded fibers that form a barrier that's soft yet strong.
