The AirSupply 4 Inch Duct Fan helps with all of your ventilation issues. The ES4 inline fan increases the centrifugal airflow vortex of your ventilation system to remove heat and humidity from grow tents, electronic equipment closets, and industrial workspaces. The airflow direction is reversible and can be used to intake fresh air into space or exhaust hot air or fumes from your space. It can even be used to pull air through odor-reducing carbon filters in grow tents.
Compared to old-school AC or DC motors, our brushless DC (also known as EC motor) and variable speed controller lets you precisely control your fan speed from 0-100% to increase efficiency while reducing noise and power consumption. With easy installation and reduced maintenance from the pre-lubricated bearings, the TURBRO AirSupply ES4 Inline Duct Fan will provide constant airflow for years to come.

United StatesI bought the popular black, plastic $25 dollar one that claims to have almost 200 CFM, and this one from AirSupply seems at least twice as strong when it is on max. Note: the black, grow tent 4" hose reduces the noise on it a great deal.
United Stateswhen i bought it it had no reviews so i took a chance. It works very well. Its all metal, the ends unscrew so you can clean the fan when needed. The lil Pot switch works pretty well. I used mine to remove excess humidity and heat from my laundry room. it get a lil loud when it is on high but the washer and dryer outweigh it in noise.It has very good suction. I high recommend the product. its high quality all around. Now it does depend on what you use it for. Mine is connected to a 4 foot ridgid dryer vent too the outside. Other that that its wide open. Only thing left is the longivity. So far so good.
