LEADER Since 1985, LEADER designs and manufactures higher performing equipment used in firefighting, fire training and Search & Rescue applications and proposes them to Fire & Rescue Services, Civil Defense, Hazardous Industries, NGOs, Maritime Services, etc. on the 5 continents. A major axis : INNOVATION To meet the evolving challenges of fire hazards and search & rescue missions, equipment must continually evolve and adapt to be more effective while ensuring maximum safety for workers. To meet these challenges, LEADER is committed to constant innovation and new technologies and has its...

VENTILATION EQUIPMENT FOR FIRE RESPONSE AND INDUSTRIAL APPLICATIONS EASY POW’AIR TECHNOLOGY: A LEADER CONCEPT VENTILATION TECHNIQUES FOR FIRE RESPONSE VENTILATING LARGE VOLUMES VENTILATION IN EXPLOSIVE ATMOSPHERES VENTILATION IN CONFINED SPACES PETROL-DRIVEN FANS ELECTRIC FANS WATER-DRIVEN FANS LARGE-FLOW VENTILATORS VENTILATION ACCESSORIES

LEADER HAS DEVELOPED EASY POW’AIR TECHNOLOGY: A POWERFUL, CONCENTRATED JET OF AIR: A LEADER INNOVATION The speed and concentrated shape of the Easy Pow'Air jet entrains surrounding air, thereby increasing the fan's flow rate. CREATES SPACE FOR RESPONSE TEAMS WORKING AROUND DOORS The force and stability of the jet gives constant and optimal efficiency from 2 to 6 m between fan and opening. This creates valuable space for interventions teams working in /around the entrance. The fans can also be positioned as close as 0.90 m. The increased distance reduces noise levels for responders. SIMPLE...

THE NEW NEO CONCEPT FOR EVEN MORE EFFICIENT LEADER FANS! Drawing on Easy Pow'Air technology, LEADER's engineers have developed the NEO concept: an optimal combination of GRILLE, PROPELLER and SHROUD The synergy between their technology and their aeraulic design significantly boosts the performance of the 420 mm diameter petrol-driven, electric, and water-driven fans of the LEADER range. PATENT PENDING Up to 20% greater flow rate, for unrivalled power in their category! An operational advantage for the firefighter: Set up compact, lightweight fans with outputs that were previously...

CONTROL THE AIR AND YOU CONTROL THE FIRE! ASSOCIATED VENTILATION TECHNIQUES: POSITIVE PRESSURE VENTILATION (PPV) Blowing a large quantity of fresh air into a fire-affected space raises the internal pressure, allowing the smoke to be controlled. The effects are rapidly obvious: Increased visibility, lowered temperature, reduced toxicity, control of smoke movement, and reduced calorific potential. These effects are beneficial to responders and trapped persons alike. Firefighters must decide which fan or fans will be best in a given situation, depending on the layout of the premises to be...

COMBINED VENTILATION TACTICS Also known as operational ventilation, this combined tactic involves using both the preceding tactics on high-rise tower blocks: 1/ Defensive ventilation is first deployed using a high-power "master" fan positioned at the foot of the building facing its entrance. 2/ With the stair well pressurized and thus made safe, the intervention team climbs up to the affected floor to set up a portable relay fan at the entrance of the burning volume. 3/ Once the exit is created, the offensive phase can begin: The air flow from the master fan is relayed by the secondary fan,...

LFV: LARGE-FLOW VENTILATORS MOBILE SOLUTION FOR VENTILATING LARGE VOLUMES Large buildings continue to proliferate and are becoming ever larger. To meet these challenges, LEADER has designed large-flow ventilators to effectively fight fires in very large places such as: Warehouses, Tunnels, Airports, Industrial Complexes, High-Rise Tower Blocks, etc. ASSURED RESULTS Being totally independent of fixed fire-protection systems, these large-flow ventilator units are mobile and capable of mass ventilating enormous volumes. EASILY MANEUVERED BY ONE PERSON LEADER trailer-mounted LFVs are easily...

CHOOSING THE RIGHT APPARATUS TO VENTILATE LARGE STRUCTURES To meet the diverse needs of fire intervention or industrial applications, LEADER has developed large-flow ventilators: One fan is an effective means of ventilating more modest large volumes such as industrial units, medium height/tall buildings, underground parking lots etc. Application Multiple fans offer flexibility of action since they can be used simultaneously to optimize blowing power. They can also be positioned at strategic points around a city or town. For ventilating very large volumes tunnels, industrial buildings, very...

ATEX MOBILE VENTILATION FOR RISK-FREE USE IN EXPLOSIVE ATMOSPHERES. To meet the need for mobile ventilation in at-risk industries, LEADER has designed special fans incorporating the most frequently requested features for use in explosive atmospheres to meet the requirements laid down in the ATEX Directive 94/9/EC and standard EN 14986-2007 specifically about fans. There are no exceptions to the latter and a certificate must accompany every machine sold. The directive covers electrical and mechanical equipment designed to be used in potentially explosive atmospheres within the European Union...

RISKS IN CONFINED SPACES Aside from general risks, confined space work exposes responders to three kinds of risk: uu asphyxiation uu poisoning uu fire and explosion There are several processes that can reduce the oxygen concentration in a confined space: The oxygen is consumed, a blanket gas is introduced, or a gas of natural origin is released. V-Box extractor/blower conversion kit CLEANING THE AIR BY VENTILATION It is possible to mitigate the causes of oxygen deficiency with ventilation techniques: uu by capture if the pollution source is localized - extracting bad air directly from close...
