- Nozzle
- Valve gauges
- Lights
The Air-Kwik System has a capacity of _______.
80 gallon
How much hose does the Air-Kwik System hold?
Holds 100’ of 1” hose (There is a tray located on both sides of the apparatus)
The red light on the Air-Kwik system turns on when the tank has approximately _____ gallons of water remaining.
25 gallons of water remaining
The Air Cylinder Pressure Gauge on the Air-Kwik system ranges from _____-_____ psi.
0-5,000 psi
The Regulator Control Knob on the Air-Kwik System is typically set for _____-_____ psi (_____psi max)
150-175 psi (200 psi max)
The tank pressure gauge shows the discharge pressure when flowing water and static pressure when the discharge valve is closed (___-____ psi)
0-300 psi
What size is the fill cap on the Air-Kwik System?
1-1/2”
Before filling or removing the fill cap on the Air-Kwik System, what should you do?
Always bleed all residual air pressure from tank before attempting to fill or remove fill cap
What is used to supply air pressure to the Air-Kwik System?
SCBA cylinder
Air-Kwik has an ASME certified water tank rated at ____ psi working pressure with a capacity of ____ gallons.
200 psi working pressure with a capacity of 80 gallons
The Air-Kwik tank is constructed with _____ stainless steel for maximum corrosion resistance. The exterior is powder coated to give a durable gloss red finish.
304 stainless steel
TRUE OR FALSE: Never put chlorine or any salt solution in the tank as it could damage the stainless steel
TRUE
Air-Kwik is powered by a high pressure (______-_______ psi) air cylinder to provide the water tank with the necessary pressure to discharge the solution
2216-4500 psi
The cylinders are connected to the air delivery system by a ________ lined double braided stainless steel hose.
Teflon
How many cylinders need to be opened for normal operation of the Air-Kwik? For maximum pressure for the entire 80 gallons _______ air cylinders should be turned on.
One cylinder; both
The water tank of the Air-Kwik remains pressurized even after all the water has been expelled and the air cylinder valve has been turned off. How must the air be released?
The air must be released either by opening the air bleed valve or releasing the air through the hose line
What should you do prior to removing the fill cap of the Air-Kwik?
Always check that gauge reads zero (all pressure removed) prior to removing fill cap
On the Air-Kwik system, there are ____ safety relief valves.
Two safety relief valves. One is on the air pressure regulator and one is on the tank
On the Air-Kwik system, the low water tank warning horn will also sound, but only for the first ___ to ___ seconds.
3 to 5 seconds
What are the Daily Checks of the Air-Kwik system?
1) Water tank full
2) Fill cap - keep hand tight
3) Bleed air valve - (keep closed)
4) Air cylinders - fully charged
5) Regulator - set to desired pressure
6) Fire hose and nozzle
7) Air test - open each air cylinder one at a time for a few seconds a listen for any air leaks. Shut off air cylinder and bleed off air pressure
TRUE OR FALSE: The Air-Kwik is powerful enough to supply both 1” lines simultaneously with a minimum loss of pressure.
TRUE. However, the water will only last half as long
TRUE OR FALSE: The Air-Kwik system is certified as a pressure vessel. Unlike extinguishers and DOT pressure vessels, periodic hydrostatic testing of the Air-Kwik system is not required.
TRUE
It is recommended that a visual inspection of the Air-Kwik system be conducted every ________.
Every 5 years
It is essential that the ________ located at the base of the air cylinder connection fitting is in place and in good condition.
“O” ring
The Alarm Shutoff Switch is ON when the bottom portion of the switch (white dot) is depressed. The switch should always be kept on except during what two circumstances?
1) To silence the horn when refilling
2) When the vehicle is being driven with tank partially full (sloshing water will activate the low water warning horn)
Is the Air-Kwik system certified as a pressure vessel?
Yes, but unlike extinguishers and DOT pressure vessels, periodic hydrostatic testing is not required.
The adjustable regulator on the Air-Kwik system should perform flawlessly for _________.
Perform flawlessly for years with minimum maintenance
The Air-Kwik system shall be pressurized how often?
Monthly
Keep a spare _______ with the Air-Kwik unit.
Spare “O” ring. Replace worn “O” rings immediately
Check the hose fittings and braided hose jacket of the Air-Kwik system for signs of wear how often?
Monthly
