The Back Draft Shutter 100mm (4") is a ventilation accessory designed to prevent unwanted air flow back into a grow room or ventilation system. It is typically used in conjunction with a duct fan or ventilation system to ensure that air flows only in the desired direction. The shutter is made of durable materials and is designed to be mounted directly onto a 100mm (4") ventilation duct. It features a one-way flapper valve that allows air to flow out of the duct, but closes to prevent air from flowing back in. This helps to prevent the intake of unwanted odors, pests, and pathogens into the grow room or ventilation system. The Back Draft Shutter 100mm (4") is an essential component for growers who want to maintain optimal air flow and air quality in their grow rooms. It is easy to install and can be used in a variety of ventilation setups, including inline duct fans and carbon filters. Show more
