Over the years, I’ve grown more & more disappointed with Cosmos’ electric fans. They used to make decent fans in the 90’s, but lately most of their fans are just 3 steps above the worst fans in the market right now, even though they position themselves as a middle class brand. I personally have never bought any Cosmos electric fans nor recommend them to anyone…until now.
This here is a Cosmos 18” HV wall fan, model 18-WIF. It’s been in the market for quite some time, I just never cared enough to look for them as they don’t sell all that well anyways. When my parents said they need another powerful fan for their warehouse and they don’t want to buy another K50UA as that fan is too strong for where they need it, I thought about getting them a Miyako 18” HV wall fan, but I hate the new plastic grille badge Miyako started putting in around 2018 I believe, and when I found out that they’ve significantly reduced the thickness of the flange, fan blade and the pitch by about 15°, I said that’s it, I’m not getting a Miyako. Now I’m in a tough position as now I’m left with Maspion, Cosmos & Sekai as my mid range option. I don’t like Maspion’s offering as they move far less air than Miyako’s, same goes with Sekai, and I didn’t trust Cosmos’ reliability. The next step down would be Sanex’s 4 aluminium bladed 18” wall fan, but that thing won’t last 2 years running all day in a hot warehouse with minimal maintenance, so that’s off my list. The next step up from Maspion & Cosmos would either be the used K50UA, or Sekai’s 18” wall fan with the thin airplane propeller style blades. But those fans cost a lot of money, plus they are too powerful for the job.
It just happens that I got a chance to see 2 Cosmos HV wall fans real close recently, and got to know it a bit better via the people that work around that fan. I learn that it actually can last quite awhile in a hot dusty environment, and that it’s actually almost as powerful as airline prop bladed HV fans that size. Intrigued by Cosmos’ new & seemingly high quality product, I recommended it to my parents. Now that I’ve recieved & looked around it real good, my sceptics about this fan is almost completely erased. The blade isn’t as sturdy as my Patton’s, but no mid range modern HV fans have blades as tough as a US made 90’s fan. The pitch on these blades impressed me though, I’ve never seen a modern day HV fan with a blade pitch this deep except for my Sekai oscillating 18” HV fan, both the floor & pedestal ones. It’s got a great range of speeds, the oscillation speed is just perfect for a fan like this, and although the front grille is held on by those annoying ring things, the ring itself is made out of metal & is pretty strong. One thing that I found surprising is how low-stress the motor in this fan is. Often times cheap HV fans run their motor on or past their full capacity, and when the blades get dusty & airflow diminishes, the motors in them sweat like crazy & potentially break the fuse. Not in this fan though. I temporarily increased the pitch by about 20° & ran it all day long on full speed without a break in a 29°C room, and the motor barely gets warm.
To be honest, I’m really impressed by this fan. Even though I’m testing this fan with it surrounded by 3 walls making it hard for the fan to pull air in from behind, it still performs like crazy. I’ve seriously never been this surprised by a modern fan before, and I just have to say it, I really recommend it over Miyako’s, Maspion’s, and Sekai’s offerings.
