Positive Pressure Ventilation and firefighting. This photo was taken near Camdenton, Missouri and originally shared on our Facebook page by alert Missouri dealer Trapper Meadors. He wrote, “Hi Joan, thought you would like this picture. Had a little house fire last week, ambient outside temperature 102 with 98 percent humidity. I’m at the end of the line through the front door with one of our VENTRY Fans right behind me doing its thing.” ~ Trapper Meadors, Precision Fire Apparatus

Transport and setup. There are a variety of ways to move a VENTRY Fan.

Side handles on all VENTRY Fans allow for one person to carry the fan against his/her chest, as James does in the photo above right. Two people can also each grab a handle, as Ken and James are doing at right. Fans with Wheels are simply rolled with one hand, as a firefighter with Spokane Valley is doing in the upper photo.

All-Terrain Versatility. How often do fire fighters encounter perfect situations? How often are there no porches or stairs, no snow, standing water, gravel, hills, landscaping, hose or other obstacles? Not often. That's why we design VENTRY Fans to work in any situation, without cribbing! You should not need a doghouse to prop up and aim your PPV fan! Legs allow VENTRY Fans to set solidly on uneven, sloped, and debris-strewn ground. Place them in the rose garden, off to the side, out of the way, and let the fire fighters use the sidewalk. Don't blow air under the porch, aim the airstream over the stairs and into the door from about 12 feet away. VENTRY Fans should be positioned 8 to 15 feet back from the target. When in doubt, place them FARTHER AWAY than you think they should be, not too close - and ALWAYS extend the legs on the fan when in use, even if only 6 inches.

Cleaning, ventilation and general control of air. We clean our shop, including the office area, production rooms, and large main bay using one of our fans and an air compressor.

We isolate one room at a time, placing a fan at the entrance. We open all windows to the outside (the larger the exit the better), and we close any doors leading to other rooms. You can not see it in the photos, but we open the huge garage doors behind the fan so that there is plenty of fresh air being pulled in from outside.

In September 2010, we used a 20GX120 model and only at about 1/3 throttle at most. That was plenty air movement for blowing the dust out the windows. While the fan is ventilating the room, we go around with the air compressor, holding down papers and blowing off everything. This makes the dust go airborn, letting the airflow from the fan carry it out the windows (taking the path of least resistance). When we are all done stirring up the air with the air compressor, the room is filled with fresh air by the fan in a matter of seconds. No residual dust.

Above photo: The fan is set quite a ways back from the entrance of one room at a time. In the three photos at right, Ken and Joan work with air compressors while the fan blows the airborne dust out the window in the background. Directly below, James blows dust with the air compressor and Joan holds things down as he goes. And that is how we do our most thorough cleaning!
