Can you add a carbon filter
Will this plug into T8 digital temp and humidity control?
I need to run at approximately 190 to 200 cfm. Would it be quieter to run a 6 inch at high speed, or an 8 inch at low speed to achieve this flow?
can this fan be used on the end of a hose connected to an engine exhaust pipe to help get the exhaust out of my garage?

AC INFINITY INLINE raxial S4 inline Duct Fan is best in the category

The make quality of this AC INFINITY raxial S4 inline Booster Duct Fan 4 inches is very good. The Fan's performance is also extremely satisfactory. The material used for making this Duct Fan looks highly durable and the finishing is very nice. The loudness during the fans working is very low and cannot be noticed. I strongly suggest that this product is better than any other brand available in the market.

Good product. It's 110v, not 230.

Good product and good support.People in India and UK, please note that this is a 110v AC source compatible and we have 230v. U need a converter or the product will have thermal runaway. Seller refunded mine and guided me in how to buy a converter too.
