4 Inch Duct Inline Ventilation Exhaust Fan with Remote Controller 296 CFM Duct Intake Fan High Efficiency Air Fan Copper Motor for Ducting Vents Bathroom Grow Tents Hydroponics

I needed a quiet variable speed duct fan for our 3D printer cabinet. This fan worked great.Ran PVC up the back of the cabinet and into the ceiling. Mounted this variable speed fan above the ceiling with the output connected to a vent through the wall. The included remote control worked great. Fan is quiet and moves a lot of air when needed.I would definitely recommend for anyone wanting to build their own 3D printer ventilation system. Excellent solution for creating a negative pressure air chamber for a 3D printer.

Remote batteries are some weird type that are not common. Fan won't even work without the remote. Completely ludicrous.Don't waste your time.

Works well, very strong air flow and quiet motor. Love that it comes with a remote for easy control.

Works great as an evening quiet blower when processing laser engraved tumblers and bottles, moved reasonable amount of air compared to others.

What kind of sorry excuse of a fan comes with a remote with a special battery that don’t come with a battery so you can’t even work said fan in the first place? Absolute trash

Would be nice to include the special battery. You can only turn the fam on by the remote, so now I have to wait to buy the special size battery.

This inline Duct Fan is working very well in my underground repair room. Great quality Ventilation Exhaust Fan. It's a great price, very quiet, provides excellent airflow, and it's very easy to install.

It's like they went out of their way to irritate you. Remote requires a very unusual 12v battery that is not included. Does the fan work? I don't know if it will work later but it sure as heck doesn't work now without that battery. And what happens if I lose the remote? Is it bricked? I'm going to have to velcro the remote to the side of the damn thing and it'll be no better than having a switch on the side to begin with.
