Nozzle Air Entrainment Round 3 - Video Series

This is the third round of videos in our Nozzle Air Entrainment Video Series. In this round of test videos we will look at interior ventilated attacks with both the fog nozzle and the smoothbore nozzle.

Nozzle Air Entrainment - Video Series

Today we have released the beginning of a 7 part video series on Nozzle Air Entrainment. These videos will walk through some of the basic concepts of nozzle air entrainment and how you can deliver some hands-on practical drills demonstrating air entrainment with various nozzle types. We will release all of these videos over the next few weeks so keep an eye out as we move along. You will see below Test 1 and 2 which will begin our video series.

TEST 1

Test 1 is an exterior attack through a window using a fog nozzle. We will begin the attack with a straight stream directed at the ceiling and then move the pattern through 30 degrees and towards full fog. You will see a drastic increase in air entrainment as we change the pattern of the nozzle. This fog nozzle was flowing 125 GPM at 100 psi nozzle pressure.

Test 2

Test 2 is the same test but we are using a 7/8" smoothbore nozzle. You will see a decrease in the air entrainment even with the increase in flow. This 7/8" tip was flowing 160 GPM at 50 psi nozzle pressure.

You will see several more of these tests coming out over the next few weeks. The next tests include interior attacks both ventilated and non ventilated.
