## Description

iPower 4 Inch 195 CFM Inline Duct Ventilation Fan with Speed Controller, Quiet Vent Blower for Hydroponics Grow Tent, Greenhouse Air Circulation, Upgrade, Black

Review: Great speed controller - Perfect for optimizing the speed of your fan. I almost didn’t get this due to many reviews saying “it does nothing at all”. This inexpensive control merely throttles the current to your fan, enabling you to reduce the speed by up to 50%. It works exactly as described and is an excellent control for reducing the speed and/or noise level of your fan. UPDATE: The controller failed after a couple weeks. iPower sent a brand new replacement, and I received it within a couple days. This is the third product I’ve tried from this company, and I have been very happy with performance and support. They definitely stand behind their products.
Review: Worked great, endured weather/elements - Used this to dampen/lower CFM of 375cfm Radon mitigation system duct fan mounted outside home. 375cfm was too high and causing air to be pulled from within the home cavity(interior, windows, attic) into the crawlspace. This wasted far more energy than would’ve been needed(electric for A/C in Summer, propane for Furnaces in Winter). While some duct fans have a potentiometer within, to do the same job as this device, my unit did not. Reportedly it is vital that the fan motor not be lowered below 50% energy supply. 2 Year Update: survived many weather events throughout four seasons per year and running 24x7x365.

## Features

- Efficient Design: Lightweight and compact fan takes up minimal space and fits in any grow room. High-quality blades and efficient flow deflector increase airflow while realizing smooth, whisper-quiet operation.
- Simple Installation: Removable intake and exhaust ends with locking tabs for simple and easy hookup. Easy to install, quick to remove and convenient to maintain. The cable length is 5.9 feet and can be easily set.
- Blower Advantages: Powerful and effective: This powerful blower with a fan speed of 2500 RPM can create an air flow of 195 CFM. Move and circulate air wherever you need and expel bad smells, cleans and freshen the air you and your plants breath
- Fan Speed Controller: One control switch for 3 settings: Variable Speed, OFF, HIGH, MED, LOW. It can precisely adjust the speed of your duct and inline fans. To avoid the risk of burning out the fan motor, controller does NOT adjust below 50%.
- Wide Applications: Perfect for improve air flow, reduce humidity, clear the air and lower temperatures. Can use in grow tents, greenhouses, grow rooms, kitchens, bathrooms, basements, locker rooms, garage.

### ⭐⭐⭐⭐ Average performance.
*by B***N on August 13, 2024*

Before installing, I discovered that the fan leaked air around center seam and around the wiring block. Had to tape seal those areas The fan also has more vibration than expected. Likely cavitation or balance issue. Installed in a ventilation capacity for a small project space. Works well enough for my application and was economical. Wouldn’t recommend for use in a concealed space or when quiet, vibration free ventilation is desired.
