CLOUDLINE A4, QUIET INLINE FAN WITH SPEED CONTROLLER, 4-INCH

This inline fan system packs the CLOUDLINE’s core innovations and premium build quality together to bring you a value package. Designed to quietly cool grow tents, rooms, and closets, and provide ventilation in various air circulation and exhaust projects. Containing an inline mixed-flow design, the duct fan can maintain airflow even in high static pressure applications. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one inline fan unit, one speed controller, UIS to 4-pin Molex dongle, installation manual, and all necessary mounting hardware. This product is a part of the UIS™ platform of grow devices and smart controllers, designed to integrate with each other to achieve your ideal environment.


FEATURES

  • Designed to quietly ventilate grow tents, exhaust odors, transfer heating/cooling to rooms, and cool AV closets.

  • Features the same build quality and innovations as the CLOUDLINE Series delivered in a value package.

  • Includes a wired 10-speed fan controller; also compatible with all CLOUDLINE Series smart controllers.

  • Mixed flow design combined with an EC-powered motor for a truly quiet and energy efficient performance.

  • Duct Size: 4” | Dimensions: 6.9 x 11.9 x 7.4 in. | Airflow: 165 CFM | Noise: 29 dBA | Bearings: Dual Ball

 

PRECISE SPEED CONTROLLER

The speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. This inline fan is equipped with the CLOUDLINE Series’ same EC-motor that is precisely controlled using PWM (Pulse Width Modulation), which enables it to run smoothly at extremely low RPM speeds without generating motor noise. Ten speed options are available with power switch and backup memory. This model can be connected to the following smart controllers to share the same programming and power source as other EC-motor CLOUDLINE fans:

  • B-Series Temperature Controller

  • T-Series Temperature and Humidity Controller

  • CONTROLLER 69

  • CONTROLLER 67


QUIET AND ENERGY-EFFICIENT DESIGN

The inline fan features a mixed flow design using a stator blade and dual hydrodynamic wind circles. This gives it a high static pressure rating, enabling it to deliver airflow even in applications where air movement is being restricted. The motor houses dual ball bearings rated at 67,000 hours which allows the duct fan unit to be mounted in any direction. In addition, the inline fan is crafted with a plastic mounting base to diminish noise as a result of fan vibration. The unit is IP44 rated to be highly resistant to dust and liquids and performs well even in harsh environments.


APPLICATIONS

This quiet inline fan system is most found in hydroponic grow tents and rooms to provide cooling and ventilation for plants. Its low noise and advanced control features make it fit for bathroom and attic settings, as well as cooling AV equipment rooms, closets, racks, and cabinets.

good toys but better for gentle / non aggressive teethers
Color: Blue
cute but not very durable. better for dogs who are not aggressive chewers even though they are young pups. when they are broken apart by teeth, the pieces are at least clean cuts. no big concerns of ingestion

Cute set for my 2-1/2 pound chihuahua puppy, and this set would also make a great gift
Color: Pink, Color: Pink
First off, I like how each piece is individually wrapped and then placed all together in a plastic bag. While it's not in a gift box, I feel like this would still make a really cute gift (that shows up in good shape, too.) For the current price of under ten bucks, this feels like a really great value for five cute toys. My chihuahua puppy is only 2-1/2 pounds, so some of these are a bit larger for her, but that's to be expected at her tiny size, and it doesn't stop her from enjoying them. These feel really sturdy to me for smaller dogs to chew on. I personally love the added "ribbons" because I think they're adorable and because my dog loves things like that. They really get her to engage with toys even more. while also giving me another way to interact with them more as I play with her. I could see how those fabric pieces may wear down over time for a larger dog, but I think it depends on how much a dog focuses on chewing on those pieces. Fortunately, the plastic toys will still be cute without those fabric pieces if anything happens to them. Unfortunately, the plastic pieces have a very slight odor. I'm super sensitive to smells, so you may not notice it at all. It's certainly not as bad as so many other plastic items, and it came right off when I washed it in dish soap (which I would do before giving these to my pup anyways.) I hope your small dog enjoys these as much as we do, and I hope you find this review helpful!

My dog wasn’t interested in these
Color: Pink
I have a 10 pound adult Maltese/Yorkie mix and she was not interested in these toys at all. They are solid construction and very firm. They have lots of bumps, humps and ridges that would likely feel good to a teething puppy. They look great but I’m not sure why they put ribbons on some of them. The ribbons would be quickly shredded with a game of tug-o-war with my dog. I deducted one point for usefulness.

doggy toy chicken leg
Color: Yellow - Fried Chicken Leg
I bought this chicken leg toy for my dog and it quickly became one of his favorites. The yellow top part has two different sections — the very top makes a crinkly sound like paper when he bites it, and the middle squeaks when he chews or presses on it, which really keeps him interested. The white bottom part is super soft and easy for me to hold, so it’s great for playing tug or just interacting with him. The size is perfect for small dogs, but it might feel a bit small for larger breeds — that said, the material quality is really nice. Overall, it feels well made, fun, and keeps my dog entertained without getting bored. Definitely a good buy.
