Moisture Capture and Pressure Drop

The MRC Air-Foil has been designed and optimized for exceptional moisture capture and very low pressure drop. All impingement type separators improve in efficiency as the velocity of the air passing through increases. As velocity rises, the ability of the product to separate smaller particles also improves. However, there is a limit to the maximum velocity allowed due to the laws of physics. Velocity at the inlet face must not exceed 2000 Ft/Min. [10 M/Sec.] due to the fact that gravity is utilized to drain the entrapped particles. After extensive testing and computer modeling, Zazz Engineering has determined air velocities exceeding 1750 Ft/Min. [8.9 M/Sec.] yields degraded effectiveness of any impingement separator. This is due to the fact that as the force exerted by the pressure of the air passing through the impingement separator approaches or exceeds the force of gravity required to drain the captured moisture droplets and particles. When this critical point is reached, any moisture captured simply remains suspended unable to drain and will quickly flood and pass through the impingement separator. Moisture capture performance for the ZAZZ MRC Air-Foil has been modeled and tested with 15 micron and 30 micron droplet sizes and the results are outstanding.

Pressure drop through the MRC Air-Foil has been carefully designed to be lower than many, if not most of the current products on the market. Upwards of 15% lower pressure drop than wider profiles (approx. 7" [179 mm]) and a phenomenal 45% lower than narrower profiles (approx. 4.25" [108 mm]) used by others, yet the Zazz MRC Air-Foil complete with the mounting enclosure is only 6" [152 mm] in depth. This means smaller air openings and increased efficiency for downstream fans and engines used in todays high air volume applications. Add to that the integrated secure weather closure that can be remotely actuated and you have a patented product that is only available from ZAZZ Engineering.

How Big Is A Micron?


A micron (short for micrometer) is a unit of measurement equal to one millionth of a meter (0.000039 of an inch). The eye of a needle is usually around 749 microns wide. A human hair is 40 to 120 microns in diameter. A postage stamp is more than 25,000 microns long.
