Best silent inline fan 4
1. Fantech FR 100 Inline Centrifugal Duct Fan, Molded Housing, 4"
Feature
9 sizes with airflow capacities between 150 and 650 CFMVibration welded seam ensures leak proof housing
100% speed-controllable
Air stream temperatures up to 140 F
They are also widely used as booster fans to move air from one room or area to another.
Description
The fans feature a fully sealed plastic housing. The housing is joined via a vibration welding process. The process uses transverse, reciprocating motion at the point of contact between the housings inlet and outlet pieces. The friction produces heat that melts the thermoplastic material at the interface. The melted material quickly re-solidifies, resulting in a fused, single-piece housing. The fused seam is inherently air tight, very strong and permanent. No screws or adhesive is used to join the housing pieces. An air-tight fan ensures that efficiency is not lost and contaminants are not spilled due to leakage.2.
