TerraBloom 4 Inch (100 mm) Inline Fan - 188 CFM Exhaust Duct Fan, Built-In Speed Controller, ETL Listed, Pre-Wired 6 FT Grounded Cord - For Use In Grow Tents With Carbon Filters, Fixtures, Attics;

TerraBloom 4" Inline Fan (Model TB-MFIF-4) is a versatile duct fan for a wide range of applications. It can be used to extract odors from enclosed environments and is powerful enough to pull air through Carbon Filters (Scrubbers) of sizes 4" x 20" or less. When using this unit with a filter, attach the fan as close to the filter as possible, pull air through the filter and out of the desired area (instead of pushing air into the filter). Keep the amount of elbows or turns in the ducting to the minimum. Each turn/elbow in ducting reduces the airflow output. This ventilation fan can also be used as an intake fan to supply fresh air from the outside, as well as mitigate unwanted moisture and stale air in the attics and basements. Due to its compact dimensions and light weight this duct fan is easy to install. This inline fan has removable duct ends to make maintenance and cleaning easier.
