## Description

desertcart.com: Hon&Guan 4 Inch Inline Booster Duct Fan with Speed Controller - 130 CFM Airflow with 6W Ultra-Low Power and Low Noise : Patio, Lawn & Garden

Review: Fantastic value - I bought this to ventilate a small paint booth I had thrown together while working on restoring some old car parts. This fan is very quiet, smooth, and pushes a lot of air. It's compact yet powerful, and the adjustment allows me to raise the speed when spray painting to get rid of overspray, and slow things down to let the paint off-gas/cure quicker. The fan has held up against a lot of spray paint being sucked right into it and has no issues. It works as I intended, and the included clamps are a bonus.
Review: Works Good - Plugged it in and worked no problem. Quality seems pretty good, no crazy vibrations. Not too loud on lower settings but I like that you can adjust it with the dial. Airflow seems adequate.

### ⭐⭐⭐⭐ More powerful than it looks
*by M***0 on August 8, 2023*

Update (1 year later)... One star deduction. The fan power supply died just short of 1 year. The fan started cycling on and off. I replaced the power supply with a 24 volt non-adjustable type and the fan is working great again. In fact, I like the air volume so much I just purchased the same model for my other son's room. The factory power supply runs extremely warm so I'm not expecting it to last. I'll be ready with a 24 volt model when it happens. I have a second floor bedroom used for PC gaming that gets unbelievably hot in the summer. Installing a booster fan in the 6" duct leading to that room mostly solves the problem. I had a 240 cfm all metal duct fan running for about three years that finally died. It was noisy and didn't seem to push as much air as advertised. This Hon&Guan model is a major improvement. Although being 100% plastic, it still easily mounts to the duct using aluminum duct tape. The claimed 345 cfm airflow is no lie. I plugged it in before installation and it rearranged all the papers in my kitchen. Compared to the twice as expensive home center metal duct fan, this one has 100 cfm greater capacity, half the power usage, adjustable speed and lower noise. My son gave me the thumbs up after a day of use. His room stays in the mid-70's (deg F) compared to 87-89 (deg F) without the fan. It is only activated when the furnace blower runs so it is not constantly on. If it lasts a few years I'll be very satisfied.
