SunStream 8 Inch 420 CFM Duct Inline Fan Vent Blower for HVAC Exhaust and Intake, Grounded Power Cord (8 INCH)

Fan has been running for roughly 3 weeks and is already rattling like theres no tomorrow. Really unimpressed with this and cannot find another way to contact seller regarding this issue.

works well not a lot of noise

This fan is EXTREMELY LOUD and there is no way to regulate the speed without having to fork out for an adjustable controller capable of handing its power. I bought this to operate as an air intake for a 2m x 3m x 2.2m grow tent and have an AC Infinity Cloudline T8 set up for extraction. It’s like comparing a Rolls Royce with a Lada. Avoid
