Question: Can you adjust the louvers to direct air upward or downward?
Document: The path of the air is pretty direct, which means it has a narrow air flow, but when you want the direct air, it is wonderful. It is enclosed and would have to do some assembly to clean it. Other then that, a great buy!
Since this is such a powerful fan, you get a lot of cooling just on the lowest setting. Remember, it is a high velocity blower so I guess the noise is a trade off for the amount of air you have blowing. The recessed handle in the back makes it easier to carry from room to room, and the directional louvres do help direct the flow of air. I recommend it, but the noise can be irritating at times.
My only complaint is that the fan's vertical directional switch will not allow the air to blow sufficiently downward. The air that comes out is powerful enough that, even at a distance, you do not necessarily want it hitting your face. If you are sitting directly in front of the fan, it works best if the stream of air can be tilted downward to hit mostly your body. My solution is to place something underneath to tilt the fan slightly forward.
Very happy with my purchase. Lasko 4930 35-Inch Remote Control Oscillating High Velocity Fan, Gray Very powerful fan, using it as an adjunct to a room air conditioner to direct cool air into my bedroom. Bedroom windows are too large and old for an air conditioning window or wall unit - tried a stand alone air conditioner which was passable but the hose kept falling out in the middle of the night and the unit was bulky. Remote is useful. Has 3 speeds but usually only need the lowest setting.
The Lasko 4930 is an excellent space-saving high velocity standing fan. On its high setting, it is very powerful. The remote control could be better. Poorly designed and you need to really direct it at the fan in order for it to work. All in all, a very good product. Recommended.
In other words, the full-speed airflow is AWESOME! Probably too much to use full-speed as a personal fan, but if you need to direct a large amount of airflow or are trying to provide circulation in a large room, this thing does the trick. I use it on low, unless I'm playing Superman with the kids, and itAs others have said, it's loud on high.
I occasionally would like to have it on and barely be able to hear it. Given that I read the other reviews, this wasn't exactly surprising though that it wasn't included.A minor complaint would be the placement of the remote receiver on the top of the fan. If you are sitting down, you have to hold your arm up and point the remote downward. It can be a bit annoying. I also wish that the fan beeped every time it received the signal from the remote.
I have the Lasko 4930 which is a High Velocity Blower Fan, along with a timer, 3 settings and a remote. Also offers adjustable louvers and oscillation. I love the fan, it is a bit louder than a standard fan, but that is to be expected with the amount of air it moves. The air even feels cool even on the hottest day. Definitely a winner.
Purchased two of these and love them. They are definitely high velocity fans. It moves serious air. They really aren't that loud in my opinion, at least considering the amount of air they move.The only complaint I have is that the lowest angle is too high. In other words all air blows slightly upward and you can't aim it down or even straight. It can be frustrating when your bed is low to the ground and the air blows above your head.
This is old, inexpensive technology. It really makes no sense. Oh and the oscillating motor sometimes get stuck requiring a push to make it start going again.That being said the fan itself is very good at cooling down a room or whatever is in its path. I would say it is effective, but I have yet to see the electricity bill since using it. If it turns out to send it through the roof I will adjust the review.
Answer: Yes you can. Best and most powerful fan I have ever owned or even seen or heard of. When and if this thing dies I will order another one, no question.
