#5 | Q: Hello. Re: IFB-8. Can this unit get a higher Merv rated filter? I would like Merv 8 or 11 if possible. A: There is no other media available for the IFB.

#7 | Q: How high temperature can the sheet metal box itself handle? I mean I dont use the built-in filter, but using some other stainless steel filter. A: Not recommended for over 140 F. The flanges have adhesive flange seals etc. Asked on 2021-01-15 by Wen |
#8 | Q: Does it matter if its placed on the intake or exhaust side of the fan? A: It does not matter physically. Typically these are on the suction (intake) side of the fan to filter any contaminants before they go through the fan. Asked on 2020-08-14 by Kyle |

#11 | Q: Can this unit be used in a house as an additional lint filter for an electric clothes dryer? A: No. You want a lint trap such as the Fantech DBLT 4W: http://www.hvacquick.com/products/residential/Dryer-boosting/dryer-booster-fans/fantech-dryer-boosters Asked on 2016-01-17 by Sean |
