## Overview

The TerraBloom 6 Inch Inline Fan delivers a robust 342 CFM airflow with a built-in speed controller for customizable ventilation. Lightweight and compact at just 5.5 lbs, it’s designed for versatile indoor use including grow tents, attics, and basements. ETL listed for safety, this fan ensures efficient odor extraction and fresh air circulation with easy installation and maintenance.

## Description

TerraBloom 4" Inline Fan (Model TB-MFIF-4) is a versatile unit 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 16" 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.

## Questions & Answers

**Q: how long is power cord**
A: 4-5’ I believe.

**Q: Is terrabloom same thing as vivosun or are they from different manufacturers?**
A: Can’t verify part numbers but they look almost identical don’t they.

**Q: Is the motor enclosed or sealed, i.e. sheet rock dust will be going through this and can do a lot of harm to the bearings.**
A: The motor in this inline fan is enclosed in a standalone plastic casing. Occasional sheet rock dust won't kill it, but if you are planning on using it in the environment where sheet rock dust is present all the time, it wouldn't be the best choice unless you'll pull the air through the intake filter.

**Q: Can the 8 inch 735 cfm be used to vent welding smoke?**
A: Yes, welding smoke will not be a problem for this unit.
