Super Air Wipes can Help to Protect a Camera Lens

2403SS

An oil and gas company was using a camera to watch a drilling rig.  During the operation, water and mud could be slung toward the camera lens, and create spots.  An operator would have to leave their position to clean the lens.  Since they were looking for a way to force the water and mud away from the lens, but it had to be clear.  Since air is transparent, they contacted EXAIR for our expertise. 

As an air barrier, customers have used the Super Air Knives to separate material/heat/gases from different areas in similar applications.   But, for this customer, they were interested in the Super Air Wipe; and at EXAIR, we state that there is more than one way to solve a riddle.  With the speed of the water and mud, I was not keen on the ability of how well the Super Air Wipe could work.  So, I decided to test it. 

At EXAIR, we offer customers the option for us to test our products in different applications.  This could also include testing your items with our products.  EXAIR offers an Application Assistance form to help get this started.  If we have the capabilities, we can setup a “mock” system to test and verify, and we can shoot a short video to present the information to you.  This can include conveyance testing, product comparisons, cleaning, cooling; and, for the customer above, air barrier testing. 

Their current operation was using a wiper to clean the glass.  Like with any wiper, material can get wedged under the wiper and cause streaks, and it could scratch the glass lens.  To stop replacing the wiper blade or in some instances, the glass lens; they were looking for a non-contact way to keep the water, sand, mud from the camera lens.  Since it was difficult for them to determine the velocity of the material that would be heading toward the camera, they requested that I use water for my test.  With a 1/4” (6 mm) O.D. tubing, they believed that it could represent a good velocity with a pressure of 20 PSIG (1.4 Bar) and a flow of 30 GPH (113.6 LPH).  This would create a velocity of 9.3 mph (15 kph).  Since the lens had a diameter of 2” (51mm), I recommended the model 2403SS, 3” Stainless Steel Super Air Wipe.  Here is a video of the results with the inlet air pressure at 80 PSIG (5.5 Bar).

Water Test

To expand a bit more on the Super Air Wipe, it is designed to blow compressed air in a 360-degree flow pattern.  This air pattern is directed at a 30-degree angle toward the center to blow the debris back away from the camera lens, just like a cone.  The Coanda effect maximizes the entrainment of ambient air into the compressed air.  This makes the unit very efficient and very powerful.  The model 2403SS Super Air Wipe has an I.D. of 3” (76 mm) which gives it enough clearance away from the view of the camera.  It is constructed of 303 stainless steel construction for corrosion resistance with a stainless-steel braided hose that connects the two halves together.  The design is very rugged for outdoor use. 

At EXAIR, we offer a 30-day unconditional guarantee on our stock products for US and Canadian customers to try things out.  But sometimes this may not be enough.  For the customer above, we were able to try something different to verify the effectiveness in keeping the camera lens clean.  And at EXAIR, we will take that extra step to help our customers.  If you have a pneumatic application that requires some additional service, you can fill out the Application Assistance form or contact an Application Engineer.  We will be happy to help you, and perhaps we can put some “focus” on a solution.

Video Blog: Venturi and Coanda Effects

In this video, I will be demonstrating the Bernoulli’s equation and how low pressure can be generated with either the Venturi effect or the Coanda effect. EXAIR uses this principle to make our products very efficient and very effective.

If you have any questions about how EXAIR uses Bernoulli’s phenomenon to create the most efficient products in the compressed air industry, you can contact an Application Engineer. We will be happy to help you.

Video Blog: Deep Hole Vac-U-Gun Demo for Cleaning Blind Holes

Cleaning out blind holes can be tricky and hazardous to your operators due to flying debris. There’s no better solution for cleaning blind holes than EXAIR’s Deep Hole Vac-U-Gun. The Deep Hole Vac-U-Gun allows you to remove the debris simply and easily, while keeping it contained in the included filter bag.

In the video below, I’ve simulated a blind hole using some 5/8″ tubing. As you can see, the debris is quickly blown up and out of the hole while captured into the filter bag without any mess or hassle.

The Deep Hole Vac-U-Gun is in stock and backed by EXAIR’s Unconditional 30 Day Guarantee. If you’d like to discuss getting one in for your facility give us a call. We can have one shipped out same day with a PO received by 2:00 ET for delivery anywhere in the US.

5 Important Factors When Selecting an Atomizing Spray Nozzle

The most recent EXAIR Webinar is up and ready to be viewed as an on demand video. This presentation showcases five important factors when selecting an atomizing spray nozzle. Throughout the webinar you will gain several key takeaways that are outside of the five factors as well. If you have a liquid spray application and are not sure where to start, this video has a wealth of information for you. As always, the Application Engineer department is also here and ready to assist as needed. We can walk through any application with you and help right over the phone, through email, or even live chat.
