Task Force Tips FJ-MX-FT MX-FoamJet ThunderFog Foam Attachment

The Task Force Tips FJ-MX-FT is the MX-FoamJet multi-expansion air-aspirating attachment for 1.5 in and 2.5 in (38 mm and 65 mm) ThunderFog nozzles. Clipped onto the nozzle bumper, it draws air into the stream and turns the foam solution from an eductor or proportioner into finished foam, with the expansion ratio adjusted by simply moving the nozzle between fog and straight stream.

The flow range of 30 to 250 gpm (110 to 1100 L/min) matches that of the corresponding ThunderFog nozzle, which is required for operation. The attachment is built from UV-stabilized polyethylene and aluminum, measures 8.6 in (21.8 cm) in diameter and weighs 5.4 lb on the product page.

Technical specification

Foam concentrates and proportioning

The manual says the FoamJet series can be used with most concentrate types including protein, fluoroprotein, AFFF and alcohol-resistant AFFF. The foam must be proportioned into the water ahead of the nozzle by batch mixing, an eductor or direct injection, since the attachment only adds air. It also warns that some foams perform better than others with these devices and that finished foam expansion and drain time depend largely on the foam chemistry. For Class A foams the manual recommends products that meet USDA Forest Service 5100-307A or NFPA 1150.

Selection and ordering guide

The MX-FoamJet range includes FJ-MX-F for 1.5 in Twister nozzles, FJ-MX-DQ for 1 in QuadraFog, FJ-UMX for Ultimatic, FJ-MX-FQ for 1.5 in QuadraFog, FJ-MX-HM for Mid-Matic and Metro 1, FJ-MX-G for 1.5 in G-Force, FJ-HMX for handline nozzles and FJ-MX-MD for the Max-Force, Max-Matic and Max-Flow master-stream nozzles. FJ-MX-FT is specifically the ThunderFog version. Low-expansion FoamJet-LX units are different part numbers and are used with the nozzle in straight stream only, otherwise foam blows back through the air intakes.

Installation and operation notes

Check the nozzle bumper first: it must be free of nicks and abrasions so that it latches and seals to the attachment. Slide the bumper into the attachment with the levers unlocked and push the levers down. In use, rotating the bumper toward wide fog raises the expansion ratio and shortens the reach, and going back to straight stream does the opposite. Like all TFT nozzles, annual service testing per NFPA 1930 is required, and units that fail must be removed from service. The manual notes that foam agents and water additives can break down the factory silicone lubricant, so check nozzle movement regularly.

Applications in GCC industry

A multi-expansion attachment turns an ordinary ThunderFog line into a foam-making branch for vapor suppression on small hydrocarbon spills and Class A coverage in warehouses, with the foam supply provided by an eductor such as the UE-250-NJ or UE-125-NF on this site. Check local authority rules on the foam concentrate and discharge.

Installation and selection notes

The attachment works only with the matching ThunderFog nozzle and a foam solution supplied by an eductor or proportioner. Clip it on, set the nozzle between fog and straight stream to adjust the expansion and test the foam quality during the training before an actual use. Rinse it after use.
