FIREFIGHTER TRAINING: VENTILATION TIPS FOR OPTIMAL AIRFLOW
To achieve optimal ventilation fan airflow, consider these firefighter ventilation training tips regarding fan placement instructions and guard option considerations.
FAN PLACEMENT INSTRUCTIONS:
SINGLE-FAN
ATTACK
The Air Cone Guard should be set back 4-8' from the door, while the StreamShaper Guard should be 6-15'. To keep ingress/egress routes clear during positive pressure operations, do not locate the fan directly in the doorway. Avoid standing in the doorway as it blocks airflow.
DOORWAY
V-ATTACK
The door is sealed top to bottom with the units at 45° angles in a doorway V-Attack, leaving a straight shot for attack lines.
*Do not block the air supply by standing behind the fan.
GARAGE DOOR
V-ATTACK
When using a garage door, open it part way and seal the doorway with the cones of air from two fans.
*Older fan methods, like a Series Attack, aren’t as effective as parallel methods.
FAN GUARD OPTIONS
Super Vac’s Air Cone Guard
Standard on all 7 Series PPVs
+ Smoke Ejectors
The Air Cone Guard produces an air stream with a wider pattern, which creates pressure evenly across the fan’s venturi. This pattern is useful for different ventilation scenarios, including open floorplans and large commercial structures, or when there is less room in front of doors, like stoops and small front porches.
Advantages of the Air Cone Guard
- Closer setup:
- Setback distance approximately 8'
- Perfect for:
- High-flow situations
- Small front porches
- Stoops
- Urban residential areas with numerous steps that limit space
- Narrow walkways in hotels, apartment complexes, etc.
- Hallways in hospitals, office buildings, etc.
- Rear entrances with decks
- Slightly less expensive and less weight
- Great for use in V-Attack
- Super Vac quality, backed with a 5-year warranty
SUPER VAC’S
STREAMSHAPER GUARD
Standard on all Valor Series PPVs
The StreamShaper Guard has a narrower air stream, which creates more pressure in front of the fan shroud, ideal for departments that need a precise airflow, usually in high-rise buildings and floorplans with numerous small rooms. This guard can be set farther from the building entrance, leaving more room for personnel to enter and exit the building.
Advantages of the StreamShaper Guard
- Farther setup:
- Setback distance up to 18'
- Perfect for:
- High-pressure situations
- High-rise buildings
- Homes with multiple small rooms
- Buildings with fewer entrance steps
- More room for operations at entrances
- Creates less noise
- Provides slightly higher airflow
- Great for use in V-Attack
- Super Vac quality, back with a 5-year warranty
DUCTING METHODS OF VENTILATION
It’s important to that when a ventilation fan is ducted, the amount of airflow decreases with the addition of the duct and every bend.
This diagram helps illustrate example bends and airflow reduction.
*Values shown when connected to Outlet of a P164SE Ventilator. When connected to Inlet of Ventilator, an additional 10% reduction can be assumed.*
