Do Portable Air Conditioners Create Negative Pressure

I was able to create a negative with this the first try :)

Easy handling with safe air pressure

I often record in my apartment or at the studio where I work - there is a ton of background noise like traffic, air conditioners, and creaky floors. The high pass filter for perfect for filtering those consistent background hums. Of course, a little fancy editing too. Arrived right in the delivery window, customer service from B&H is great as always.

[This review was collected as part of a promotion.] This has been a lifesaver especially during the summer when everyone is blasting their fans and air conditioners and risking outages. I’ve had my power go out multiple times in a span of a week and I had enough time to save everything I needed to. The size also helps as my small apartment is already pretty cramped.

I also have a Giotto Rocket Air Blaster, which I love. I decided to buy the VisibleDust blower based on the theory it will reduce the risk of blowing dust on my sensor. I don't know how real that risk actually is... The air is pushed through a filter to minimize the risk of blowing dust onto your sensor. Because of this, the air pressure you can generate is lower than for the Giotto, but I suppose you don't want too much pressure against your sensor anyway. It's sufficient for blowing dust off your lens, too. Quality is solid.

I have been using Furman power conditioners for many years, mainly to provide a portable power strip with reasonably clean power. Providing adjustable light to rack components in often dim stage conditions is more than welcome too. I use the Furman with short ANSI power cables (12") to minimize the clutter in the backside of the rack. At 12" in depth, the backside of the Furman is short enough to clear the rear cover, yet long enough to reach without skinning my knuckles. Kudos! Furman. How about a 1-space Furman UPS?

using this product on my Tamron lense very clear and made well. Do not know of a negative feature yet

I don't care how strong you are, if the filter seizes on the camera, you won't get it off with your fingers since you will create uneven pressure and increase the bind. These wrenches spread the pressure evenly around the filter and make it easy to remove.

This is just large enough to give you enough air pressure to get troublesome dust off of your gear, but not too large. Adjustable nozzle is great especially when I am holding multiple items in my hands - trying to keep everything facing down (lens and body) when swapping lenses.

Quality tripods, anyone looking for a level tripod but at a cheap price, this is the tripod, it holds up well in the winds, and it also has air pressure as soon as the screws are released so that your flash will not drop your lighting signal quickly but slowly
