I have written blogs about laminar and turbulent flows as related to the Reynold’s number. Now, let’s demonstrate the difference between the two flows and the advantages of laminar flow from EXAIR’s engineered air nozzles; as demonstrated by our VariBlast Safety Air Gun.
In industrial settings, having a single air nozzle or other blowoff product is often not the scenario that is seen. Many applications require multiple points of blowoff, even if not in the same direction or for the same position within the machine. In the scenario where multiple nozzles are used, sound levels can get tricky to calculate and is often thought of as a mystery. If you follow our blog then you may have seen this excellent blog that shows all the math behind calculating the total decibels when multiple sources of noise will be present. The video below gives a demonstration of utilizing two of the EXAIR model 1100 – 1/4″ FNPT Super Air Nozzle.
In the video you see a model 1100 being operated and producing a sound level of 74 dBA from 3′ away from the nozzle point. When the second nozzle is turned on (also producing 74 dBA individually), the pressure is adjusted back up to the same input pressure and the sound level meter registers 78 dBA from 3′ away. Following the math laid out in the “excellent blog” link above, the sound level calculated comes out to be the same 78 dBA that is shown in the video using EXAIR’s Digital Sound Level Meter.
If you would like help determining the sound levels within your facility, check out the EXAIR Digital Sound Level Meter as well as reach out to an Application Engineer.
Below is a video showcasing the model 6850 Drum Cover. The Drum Cover is a new product from EXAIR that will help to filter pneumatically conveyed products from the air used to move them. If you would like to discuss a conveyance application or whether this product would fit your need, please contact an Application Engineer.
The video below will give a brief demonstration on the importance of point of use filtration in order to remove unwanted material such as water, scale, particulate and oil from your compressed air stream. Point of use or end-use filtration will keep your air clean and your compressed air products running smooth. If you have any comments or questions, please feel free to contact us.
