Tempest V Leader fan/blower
I was just wondering which fan/blower you guys prefer if you have tried both types.
I know Tempest tend to go for a sealing fan and although Leader have the same they have one on the market at the moment that can create a seal for the most from 4 & 6m away from the inlet.The leader one also will tilt downwards 10' which I see as a tremendous bonus for dealing with basement and subterranean incidents.
Your comments gents are very much appreciated.
Tempest v Leader fan/blower (and VENTRY)
Hello, Jonners. My name is Joan and I do the marketing for J. Neils Enterprises, Inc. We manufacture VENTRY PPV fans. I came across this thread and appreciate the opportunity to add a few thoughts. I'm sorry it's so late!
The major fan brands utilized by fire/rescue are Ramfan (by Euramco), Supervac, Tempest, Tele-Aire, Unifire, Groupe Leader and VENTRY. Iím not sure on availability world-wide of each brand, but these are the main brands, I believe.
On tilt: All brands include models with Honda gas/petrol-powered engines. Honda GX-series engines have low-oil shut-off features that will kick in if tipped more than 20 degrees. Besides our fans, I donít know to what degree other fans are adjustable, but all are ultimately limited by the motors.
Let me offer that other important considerations when choosing PPV fans should include the quality of the air stream, size, weight, noise level and carbon monoxide levels. By far the most important feature, however, is air volume. (For coordinated attack, not just post-knock-down mop-up, this is a given, per instructors/researchers in ventilation.) Beware that fans with higher horsepower do not necessarily push more air! Air volume is usually expressed as cubic feet per minute (cfm) or meters cubed per second (m3/s), and can be measured by thrust.
Most of the important specs are available on the manufacturersí websites so customers can choose the best fan for their needs with just a little research. No matter what brand is ultimately chosen, positive pressure ventilation is an incredible, potentially life-saving tactic when used appropriately with education/training. Thank you for having this discussion and for letting me take part. (And thanks to Chief Meyer for mentioning VENTRY fans.)
Be well, ~ Joan Neils, J. Neils Enterprises, Inc.
