TFT Inline Foam Eductor Manual

Warning: Read instruction manual before use. Operation of this device without understanding the manual and receiving proper training is a misuse of this equipment. Users who have not read and understood all operating and safety instructions are not qualified to operate this eductor. This manual should be kept available to all operating and maintenance personnel. This instruction manual is intended to familiarize firefighters and maintenance personnel with the operation, servicing, and safety procedures associated with the eductor.

2.0 Safety

The eductor is designed for Class A and Class B foam concentrates. If you intend to use the eductor for liquids other than Class A and Class B concentrates and water, we urge you to contact the Task Force Tips Engineering Department. The use of other liquids may void the warranty and subject the user to hazards not addressed in this manual. The user assumes all risks for non-intended uses. • Make sure there is enough foam concentrate prepared before fighting fire. TFT’s eductors are calibrated 15% more than the nominal rate, or half percent point, which ever is less. Per FOAM EQUIPMENT AND LIQUID CONCENTRATES – UL 162, the liquid concentrate induction rate of a proportioner, expressed as a percentage of the flow rate of the mixed water plus concentrate solution, shall be minus zero (0) percent, plus thirty (30) percent of the manufacturer’s specified induction rate or one percent point, whichever is less.

Make sure the meter head set to OFF position and the correct nozzle and hose lay are securely attached to the eductor before the hose line is charged.
Make sure the nozzle gallonage matches eductor’s gallonage.
Make sure the hose lay does not exceed the maximum listed in the operating instruction.
Make sure that the meter head is set to the correct concentration for the type of foam being used.

Danger: Foam concentrates can be ineffective if not used at the correct percentage. Lack of foam can place operator at risk of injury or death. Establish foam flow before advancing into hazardous situations. Make sure you do not run out of foam concentrate before the task is complete. Check concentrate level periodically and keep an adequate supply on hand.

Warning: Do not use Class A foam on Class B fires or Class B foam on Class A fires. Note: Some foam concentrates are universal and can be used on Class B fires and spills and as a wetting agent on Class A fires. (Refer to foam concentrate manufacturer’s recommendations for proper foam choice.)

Warning: Improper use of foam can result in injury or damage to the environment. Follow the foam concentrate manufacturer's instructions and fire service training to avoid the following:

Using the wrong type of foam on a fire, i.e. Class A foam on Class B flammable liquid fire
Mishandling of concentrates
Plunging foam into pools of liquid fuels
Directing foam onto yourself or other personnel

Warning: There is a wide variety of foam concentrates. Each user is responsible for verifying that any foam concentrate chosen to be used with this unit has been tested to assure that the foam obtained is suitable for the purpose intended.

3.0 General Information

Eductor Types:
UE-060-IF Inline Eductor 60 GPM 1.5" NPSH
UE-095-IF Inline Eductor 95 GPM 1.5"NPSH
UE-125-IF Inline Eductor 125 GPM 1.5"NPSH

The eductor proportioning rate ranges from 0 .25%,0 .5%, 1%, 3%, to 6%.

TFT’s eductors can be used with 0.25% or 0.5% class A foam concentrates for wildland, rural and urban fire suppression on Class A fuels (wood, paper, combustible materials). On Class A materials the eductors are intended to be used for direct extinguishment, overhaul, and wetting of fuels. Some foam concentrates are corrosive, we recommend using only Class A concentrates that have received USDA and USFS approval.

On class B materials, the eductors are primarily intended for vapor suppression or extinguishment. They can be used with high viscosity 1%, 3%, 6%, 3x3% and 3x6% Alcohol Resistant Class B concentrates on flammable liquids containing polar solvents.

The eductor can also be used with plain AFFF concentrates rated at 1%, 3%, or 6%, with various freeze protected foams, and with FFFP foam types. These foams generally have a lower viscosity than the calibration viscosity of the TFT eductor and will be inducted faster than expected resulting in stronger concentrations. While this does not degrade foam quality, it does reduce the operating time for a given foam supply.

Standard inlet operating pressure is 200 psi on all eductors (1400 kPa/14 bar).

3.1 Part Identification

The eductor can be split into two parts by grasping the locking ring and retracting it fully to separate the metering head from the eductor body. All the foam passageways can easily be inspected. The foam passageway into the eductor contains a free-floating check disk with three fins. The check disk is pressure activated to keep water from coming out of the fire hose and back into the foam pail. The metering head contains a red back flush button that can be depressed to open the check disk. The metering head also has a large proportioning knob that can be rotated to align a ball valve to six different detent positions: Off Ľ% ˝% 1% 3% 6%. Each foam setting has a precision sized metering orifice in the valve ball. The eductor cannot be operated between settings, as the metering orifices will not line up properly. The setting on the proportioning knob lines up with the white indicator ball.

3.2 General Operating Instructions

1) Choose the right foam concentrate (see section 4)
2) Lay the right hose (see section 5)
3) Connect the right nozzle (see section 6)
4) Charge the hose and open the nozzle fully to establish the water flow.
5) Adjust the pump pressure so the eductor inlet is set at 200 PSI.
6) Put the wand in the bucket and rotate the percentage knob to the desired concentration.

3.3 Cleaning Eductor

After use take the wand out of the bucket and turn down the pump pressure below 75 PSI. Shut off the nozzle. Restrain the wand and expect a rapid discharge of water especially at 6% setting. Push the red flush button and run fresh water through the wand and metering head on each setting until there is no visible foam in the flush water. Retract the lock ring to remove the metering head. Turn off the water supply and remove the eductor from the hose so that any remaining foam residue can be washed from the wand, metering head, and eductor.

Caution: Do not back flush above 75 PSI. Rapid back flush discharge from the wand could cause injury. The back flush push button is pressure activated and must not be forced at pressures over 75 PSI (5 bar).

4.0 Foam Selection

Actual foam concentrations vary with changes in water flow, foam concentrate temperature and viscosity. The user must verify that the concentrate’s performance is suitable for use in their application. In all cases, the manufacturer’s recommendations must be followed.

Caution: Class A foam concentrates are generally less viscous than Class B foam concentrates. Using 1% Class B foam percentage setting to educt Class A foam, may cause the actual Class A foam percentage to be more than 1%.

4.1 Class A Foam

4.2 Class B. Foam

4.3 Foam Compatibility

Caution: Do not mix different types of foam concentrates or foams of the same type from different
manufacturers. Mixing of foam concentrates can cause the contents of the foam tank to gel and
produce unpredictable results. Clean tank and foam passages thoroughly when changing foam
types.

Medium Expansion Nozzle — produces the greatest expansion ratios. It should be used on Class B fuels for vapor suppression and Class A fuels when a longer lasting insulating layer of drier foam is desired.
Low Expansion Nozzle — can be used with either Class A or B foam solutions. Reach is slightly less than the smooth bore. It should be used on Class B fires for extinguishment and Class A fuels to soak the fuel with a wet foam solution.
Straight Stream Nozzle — is for Class A foam solutions. Foam expansion will be negligible. It should be used where maximum reach or penetration is desired.

The class A foam used for calibration is the “Knock Down” from National Foam. The calibration viscosity is 20 Centipoise.
The class B foam used for calibration is the “Universal Plus 3% /6% Alcohol Resistant Aqueous Film Forming Foam” (AR-AFFF) from National Foam. The calibration viscosity is 2892 centipoise tested with Brookfield #3 Spindle @ 30 rpm.
TFT’S eductors were calibrated with 1ľ" Conquest Hose.
UE-060-NF calibration hose length is 300 ft.
UE-095-NF calibration hose length is 250 ft.
UE-125-NF calibration hose length is 150 ft.

Per UL-162, TFT’s eductors are calibrated 15% more than the nominal rate, or half percent point, which ever is less. Therefore actual time to empty 5 gallons is less than the values in table.

5.0 Maximum Hose Lay

The maximum hose lay is based on the back pressure. Pushing the foam solution thru the hose and nozzle causes back pressure on the eductor exit. If the back pressure is over 130 PSI the eductor will not work. However, when proportioning rate is no more than 1%, 140psi back pressure is acceptable.

Elevation loss adds to the back pressure when the nozzle is higher than the eductor. For each foot in vertical height there is 0.4 PSI elevation loss.

Warning: Do not exceed 130 PSI back pressure. Excess back pressure causes loss of foam flow resulting in risk of injury or death from an ineffective stream. Verify that adequate foam flow is established and maintained.

The following table shows the reference friction loss based on water flow, hose length and size. To calculate the back pressure, add the
nozzle pressure, hose friction loss, and elevation pressure loss together, and make sure the sum does not exceed 130 psi.

Friction loss varies with different brand hoses. Please specify the friction loss of your own hose.

The nominal flow of the eductor is the sum of water plus foam concentrate when set at 6%. The eductor should always have 200 psi at the inlet. The water flow does not change with different percentage settings, however, the inducted foam concentrate will change when the percentage setting is changed. Therefore, the total flow exiting the eductor is lower at .25% than at 6%. Lower flow rate helps reducing nozzle pressure and hose friction loss. Longer hose can be used when proportioning rate is less because less work is needed to move less concentrate.

6.0 Nozzle Selection

Eductors work with any nozzle whose gallonage is equal or larger than eductors’. However, if a larger gallonage nozzle is used, the reach of nozzle and the proportioning rate of the eductor will be compromised.

Fog-type nozzles have the greatest reach in the straight stream position. The finished foam is produced as the stream projects forward, and the greatest expansion is at the end of the stream. While straight stream gives maximum reach, it can also splash flammable liquids if not carefully applied. The stream impact can be softened by deflecting the stream off nearby objects. The stream can also be trimmed to a 10-15 degree pattern which gives good reach and creates a softer “snow-flaking” effect at the end of the stream.

The expansion ratio is the amount of finished foam produced compared to the volume of foam concentrate/water solution used to generate the foam. For Example: A 10:1 expansion ratio will produce 950 GPM of finished foam from a 95 GPM nozzle. Non-aspirated automatic nozzles can produce expansion ratios of 6-8:1 when measured at the end of the stream. By maintaining a constant nozzle pressure, automatic nozzles keep the velocity of the stream high. Large amounts of air are pulled into the stream and mix with the foam concentrate/water solution as the stream leaves the nozzle.

Air-aspirating devices, such as the TFT FOAMJET, allow a wider selection of foam concentrates to be used, and can produce a better quality of finished foam. Air-aspirating attachments will, (1) improve the 1/4 drain time, (2) produce a more uniform bubble structure, (3) improve the burn back resistance of the finished foam, and (4) the foam blanket is visibly thicker. This thicker foam blanket has better
vapor suppression and is longer lasting than foam from non-aspirated nozzles. The final expansion ratio and, therefore, the amount of finished foam, depends on the type of foam concentrate being used.

Warning: The nozzle must be operated fully open to prevent excessive back pressure which will prevent foam pickup. Lack of foam can result in injury or death.

The following tables list the compatibility between eductors and nozzles. NOTE: A 75 psi nozzle will result in lower nozzle pressure and shorter stream reach.

Parts 11, 29 and 32 are flow calibrated as indicated by the number of grooves.

Caution: Do not intermix metering heads with eductor bodies of different flow rates. Intermixing can cause weaker or stronger foam than expected resulting in risk of injury as the ability to control the fire is compromised.

10.0 Foam Bucket Arrangement

The foam suction hose is matched to the eductor and must not be lengthened or foam flow will be reduced resulting in weak foam. (as shown in location D). The other three locations (A, B, & C) show the recommended foam bucket arrangement.

10.1 Foam Supply Logistics

When using class B foams for extinguishing burning pools of liquids a continuous foam supply is essential. Foam flow may be interrupted by not changing foam buckets quickly or by switching the metering head to OFF. Foam buckets can be difficult to move or open quickly, therefore training and planning for a continuous foam supply is recommended.

Danger: Lack of foam can place operator at risk of injury or death. Establish foam flow before advancing into hazardous situations. Make sure you do not run out of foam concentrate before the task is complete. Check concentrate level periodically and keep an adequate supply on hand.

11.0 Maintenance

Eductor does not need regular maintenance. However, make sure the eductor is fully cleaned after each usage. Otherwise, the foam concentrate may dry inside and around the percentage ball resulting in plugged metering orifices. Look down inside metering head and check valve to insure clean passageways.
