## Description

AC Infinity CLOUDLINE S6, Quiet 150mm Inline Duct Fan with Speed Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics, 6-Inch : desertcart.co.uk: DIY & Tools

Review: Quality product. - Quality product. Does the job it's meant to very nicely
Review: Quite and the remote control is really excellent. - I replaced a built in fan in my kitchen extractor unit (failed motor) by mounting this unit in-line in the extract duct. The remote lead was long enough for me to mount the remote in my old unit and yet have the fan mounted well away. I mounted the fan on wires thus reducing any transmitted running noise (I would not expect much anyway as such a smooth running motor). The level of extraction is variable and perfect for the application. Excellent product 10/10. Fully recommend.

## Questions & Answers

**Q: when inside the tent at 1-2 settings, can this be heard on the outside atall?**
A: Hello,

Quiet and powerful used on a 4x4 tent.Settings with two different size fans. At night it exhausts just enough air to keep the humidity right without cooling down the tent hardly at all using outside air intake and it is very quiet.

Best Regards

**Q: How does this work please? Does it heat the grow? Im confused as i want to set the temp for my grow but to cold.**
A: No, it extracts warm air out trough a vent, cooling the area down and removing humid air.

The fan has a controller to allow the fan to move up and down the settings 1 - 10 to keep the area at the desired temperature and RH.

To heat the area up to you need a heater with a thermostat

**Q: Got my ac infinity cloudline s6 today  -it only has a 2 pin  plug ,i thought it came with a adaptor to uk plug?**
A: strange - mine came with a UK plug when i ordered it last year!

**Q: Bought in uk but has us 3 pin plug! is this uk rated, what plug is required?**
A: Hello,

Products with electrical plugs are designed for use in the US. Outlets and voltage differ internationally and this product may require an adapter or converter for use in your destination. Please check compatibility before purchasing.

*by C***R on 7 February 2021*

For me the ac infinity fans were a game changer, got my environment dialled in just how I need it and with ease to, I purchased an s6 and a t4 reasonably priced I might add, they work perfectly together! These fans are great quality and I was even more pleased when they already came with a connector attached to a U.K. plug! Overall 10 out of 10 for these fans, hats off to AC infinity, they’re so quiet and just a quality product, I will never use another make again, if you’re thinking about buying one just do it, you will not be disappointed
