Task Force Tips introduced several new products – a high-volume, low-level strainer, the Oasis Hydrant Assist valve and the Jumbo Water Thief valve for large-diameter hose.
The company said its new strainer provides up to 1,500 gpm at draft and has the lowest loss of any strainer in the world – 0.5 psi at 1,500 gpm. The clog-resistant, stainless steel filter has over twice as much flow area as a 6-inch hose, according to TFT.
“Its unique swiveling design holds the strainer flat to the bottom of the tank, maximizing available water flow,” said Rod Carringer, TFT’s vice president of sales and marketing. “In addition to allowing us to utilize all available water, the low-level design prevents unwanted whirlpools that can cause the loss of prime.”
The strainer can be stored in an apparatus compartment, or pre-connected on a front section. “That’s one of the things that we established early on in design,” Carringer said. “The strainer had to be the about the same size as other strainers on the market, so that it could be easily stored. But that’s where the similarities begin and end.”
The powder coated anodized aluminum body gives maximum corrosion resistance with minimal weight (20 pounds). An optional integrated jet siphon is ideal for the rapid movement of high volumes of water between supply sources, Carringer said.
“The unique coupling system allows for easy attachment to suction hose by a single firefighter even in the worst fireground conditions,” he said.
TFT said its new Oasis Hydrant Assist offers a new safety feature – the built-in ability to maintain a steady, sustainable water supply even if the secondary boosting apparatus loses power.
“The Oasis Hydrant Assist Valve is the next step in high flowing hydrant valve assistance,” Carringer said. “TFT engineers kept hearing how competitive valves in the market were horribly [flow] inefficient and heavy, so they focused their new design on high performance, light weight, and compactness.”
Weighing in at just under 35 pounds, the Oasis valve can be used for inline pumping during relay operations or as a hydrant booster. It meets National Fire Protection Association slow-close requirements, meets criteria for the NFPA 1965 standard for fire hose appliances (max operating pressure of 250 psi) and meets the 900-psi hydrostatic strength test, according to TFT.
The top-mounted parallel shaft gear (a part of the slow-close mechanism) features a position indicator that shows the operator if the valve is in straight hydrant flow or in boost operation. In addition, a separate clapper indicator shows the position and/or movement of the valve’s stainless steel clapper valve.
“We expect these valves to be a great tool for departments looking at ways of improving their fire flows.” Carringer said. “Designed specifically for 3.5-inch, 4-inch and 5-inch hose lines, this valve can easily improve water delivery in some cases by as much as 100 percent.”
TFT’s 5-inch-by-2-1/2-inch Jumbo Water Thief is the newest addition to its large diameter hose (LDH) line, a rugged valve with two valve discharge ports and a high volume waterway to help firefighters extend attack lines from the main water supply.
“Like any valve in our LDH line, the Jumbo Water Thief was designed for maximum flow at minimum loss,” Carringer said. “This valve is rated at 500 gpm per 2-1/2-inch discharge port.”
The thief is available with or without a pressure relief valve (PRV), which is adjustable from pressures of 50 to 200 psi in easy-to-see 25-psi increments. TFT said its PRV valve has become a standard with many truck manufacturers because it meets stringent NFPA standards.
“Everyone realizes that having a valve close down can do tremendous damage to a pump or hose line,” Carringer said. “When you’re dealing with a number of flows and a lot of pressure, the PRV offers an extra measure of protection.”
