What is a TFT nozzle?
The TFT Working Fire nozzle delivers revolutionary performance when you need maximum flows for a “working fire.” For everyday use, it is a 150 GPM @ 75 psi or 160 GPM @ 50 PSI fixed GPM nozzle, but when you need even more GPM, the nozzle’s exclusive pressure relief system dramatically limits nozzle reaction.
What are the different types of fire nozzles?
There are five basic nozzle types:
- Smooth or solid bore.
- Fixed orifice or single gallonage (sometimes called variable pressure/variable flow)
- Selectable or adjustable gallonage.
- Automatic or constant pressure.
- Multi-purpose nozzle (combination smooth bore and fog)
What does Task Force Tips do?
Task Force Tips (TFT) is a leading manufacturer of life saving equipment for fire and rescue departments around the globe. We’re looking for individuals to join our mission in saving lives and protecting property.
What nozzle does FDNY use?
Response: The predominate nozzle used by FDNY engine companies is a smooth- bore controlling nozzle with stacked outer stream tips ranging in size from 1 1/8- If you are a current subscriber, login here to access this content.
What is TFT full?
A display screen made with TFT (thin-film transistor) technology is a liquid crystal display (LCD), common in notebook and laptop computers, that has a transistor for each pixel (that is, for each of the tiny elements that control the illumination of your display).
What is TFT branch?
TFT Branches: The barrier between the firefighter and the fire, combining high level performance, simplicity and safety of use. The partenership between TFT and Terberg DTS delivers best in class products coupled with world reknowned 24 hour service and support.
What are fire fighting nozzles?
Fire nozzles can provide a constant flow or allow firefighters to select the most appropriate flow rate and operating pressure for fire fighting. A fire nozzle connects to a fire hose to deliver water or fire fighting foam to extinguish a fire.
What is a Playpipe nozzle?
The underwriter’s playpipe is a straight-stream nozzle that discharges water streams over long distances. Playpipes feature a remarkably smooth, long pipe—often 30 inches or so—that straightens a stream of water while reducing turbulence. Firefighters originally used playpipes as outdoor hose nozzles.
What is a smooth bore nozzle?
Smooth Bore Fire Nozzles
Smooth bore nozzles also use the lowest engine pump pressures, allowing for maximum reach. Smooth bore nozzles are often referred to as solid bore nozzles because they produce a solid stream to provide maximum reach and penetration to the seat of the fire.
What do you pump a fog nozzle at?
Conventional fog nozzles have a fixed or selectable gpm setting. These settings correspond to a particular discharge orifice, or tip size. In order for a conventional nozzle with a fixed opening to operate at the correct nozzle pressure of 100 psi, the proper gpm flow must be supplied.
Is TFT and TN same?
TFT is basically another way of saying “LCD panel”. TFT does not refer to any specifiec panel technology. TN panels generally are good enough for most people especially if they do not want to spend a lot of money.
What is TFT made of?
TFTs have been widely used in the applications of displays. Traditional TFTs are use silicon based (silicon, amorphous silicon, microcrystalline silicon, or polysilicon), cadmium selenide, or metal oxides as semiconductors.
What TFT means?
thin-film transistor
A display screen made with TFT (thin-film transistor) technology is a liquid crystal display (LCD), common in notebook and laptop computers, that has a transistor for each pixel (that is, for each of the tiny elements that control the illumination of your display).
What is a fire hose nozzle called?
A fog nozzle is a firefighting hose spray nozzle that breaks its stream into small droplets.
What is difference between a smooth bore nozzle and fog nozzle?
Smooth bore nozzles outperform fog nozzles in that they have more operational benefits, which include: greater reach and better penetration. less nozzle reaction except for the 50-psi fog nozzle. less likelihood of being clogged by debris.
How many GPM is a master stream?
A master stream is basically defined as a heavy-caliber stream delivered through a master stream water delivery appliance. A master stream is used when flows surpass 350 gallons per minutes (gpm), becoming too difficult to be delivered from a handline operation because of nozzle reaction.
What psi Do you flow a master stream at?
Master Stream Devices: Nozzle Pressure + 10 PSI for the device. Older devices with multiple intakes and stream straightener Nozzle Pressure + 20 PSI.
Which is better TFT or LED?
Performance wise LEDs are far better than TFT and LCD displays. LEDs provide high contrast than LCDs/TFTs. In a LED display, you will see perfect black and perfect white which is not able to see in TFT or LCD. LED has a better viewing angle.
What is better TFT or IPS?
IPS (in-plane-switching) technology is almost like an improvement on the traditional TFT display module in the sense that it has the same basic structure, but with slightly more enhanced features and more widespread usability. IPS LCD monitors consist of the following high-end features.
How does a TFT work?
TFT (Thin Film Transistor) is a thin film field effect transistor. The so-called thin film transistor means that each liquid crystal pixel on the liquid crystal display is driven by a thin film transistor integrated behind it. This can display screen information at high speed, high brightness, and high contrast.
What is a firefighter nozzle?
What do you pump a smooth bore nozzle at?
Smooth bore nozzles generate effective streams at nozzle pressures as low 30 PSI, but the stream will degrade at pressures over 60 PSI.
What is a smooth bore nozzle used for?
What psi do you pump a standpipe?
In buildings constructed after 1993, NFPA 14 requires standpipe outlets to flow a minimum of 250 gpm at, as mentioned previously, a minimum pressure of 100 PSI.
What PSI Do you flow a master stream at?
