- Sand & Mud Eductors
Fox recently supplied sand & mud eductor to an environmental remediation contractor. This sand and mud venturi jet pump was dropped down through 25 ft of six inch ID pipe to suck up contaminated sludge and mud at the bottom of a well. Both the motive water line, which drives the eductor, and the eductor discharge pipe, which sends the sludge to the surface, slipped though the 6 inch pipe dropleg. Most importantly, the bottom of the eductor is equipped with downward directed jets that stir up and fluidize the sand and sludge that must be sucked into the eductor and sent to the surface for disposal. A similar installation made at the Playas Hydroelectric Plant in Antioquia Colombia operates so successfully that Fox is now discussing similar eductors for another project in Colombia.
- Fox Ejectors evacuating residual fuel vapors
During a routine maintenance of aircraft tanks, a major commercial carrier needed to vent residual jet fuel vapors from the wing tanks. Like all tanks and vessels filled with any type of fuel, the possible release of jet fuel fumes created an explosion hazard. For this reason, the airline operator contacted Fox to supply a venturi air ejector to capture these vapors before release to atmosphere. This solution, once intended only to mitigate an explosion hazard, now has a dual function – to capture greenhouse gas and decarbonize ground-based maintenance. Fox supplied a small 1-1/2” ejector supplied with air at 20 psig. This ejector was originally designed in 2004 and has been supplied often to many of the airlines’ maintenance facilities all over the world.
- Fox H2 Venturi ejectors for fuel-cell-driven aircraft
Fox Venturi ejectors have been used to recirculate hydrogen from fuel cell stacks for 20+ years, but we are very excited about having these H2 jets installed on a number of prototypes of fuel-cell powered aircraft.
- One blower drives three eductors for handling abrasives
In a vastly simplified conveying arrangement – compared to any possible option with rotary valves – one blower is used to simultaneously drive three ceramic-lined eductors. Each eductor is under a different hopper. Each eductor then conveys the abrasives to a different destination. The result – three conveying systems, only one blower with no moving parts.
- Tool-steel lined Eductor conveys aluminum chips
Aluminum chips, although a soft metal, can be extremely abrasive when conveyed at rates of 5 tons/hr. Fox is supplying conveying eductors with replaceable ceramic liners as well as replaceable tool steel liners. In addition, some portions of the eductor internals are clad with tungsten carbide.
- Synthetic Wood Manufacturer uses Fox Eductors to convey resin
This major producer of synthetic wood and decking has installed another Fox eductor in their new manufacturing line to convey resin pellets with no moving parts – so their production can continue with no maintenance shutdowns from resin conveying. This is just another of many producers of building products that use Fox venturi eductors – including producers of roofing tiles, sandpaper, chipboard, and grout.
- Larger eductor after conveying dough pellets in Thailand since 2006
A major food processor in Thailand has been using Fox 4 inch, fully sanitary, food grade eductors to reliably convey dough pellets, since 2006. Pleased with their service, they recently ordered a 6 inch sanitary eductor for a new production line. Air is supplied to the eductors from reliable, maintenance-free regenerative blowers, from Fox Valve.
- Still conveying graphite flakes after 24 years of service
One of the world’s largest manufacturers of graphite powders has been using Fox Solids Conveying Eductors to convey graphite from their grinders and screeners since 1998, with almost no wear. Their most recent order was for a 4” eductor to pneumatically transport from a large dust collector through 400 ft, to additional processing.
- Another chip manufacturer orders TFE lined eductors for acid dilution
Fox Teflon lined liquid/liquid eductors, manufactured using machined TFE internals and TFE lined, stainless fittings, are installed at more semiconductor manufacturing plants in Asia, EU and USA, in sulfuric acid dilution applications.
- 33 years later, a Fox conveying eductor handling toner needs replacement
Back in the 1990’s, over one hundred Fox Eductors were installed at one of the largest toner plants in America – pneumatically conveying ultra-fine carbon from screeners, grinders and totes, with no fugitive dust and no blowback. In January 2022, Fox received a call to replace a 3” eductor, which had (finally) worn out. Shipped and installed in under a week.
- More Venturi eductors installed on 3D printing systems
After thorough testing with Fox venturi prototypes, Fox’s customer is now installing dozens of venturi eductors to convey dense metal powders with insert gas on their additive manufacturing products. These high performance eductors include numerous design features to meet exacting customer requirements.
- Slurry pick-up eductor ships to Prudhoe Bay Alaska. To suck desiccant from a barrel and convey to air dryer vessels
Prudhoe Bay Alaska is not a good place to install equipment that needs frequent maintenance. Fox slurry eductors are used to suck desiccant powder up from barrels and convey with water to air dryers. With no moving parts, they are expected to operate reliably for many years.
- Slurry eductor conveys fish pellets 100 m …. sprays out to feed Scandinavian salmon
This aquaculture company in Scandinavia started by testing a Fox 4” PVC eductor under a bag dump station – shipped in a week. Feed pellets were manually dumped into a hopper above the eductor. Using seawater at 4 barg/60 psig – the eductor conveyed the fish pellets through 50 – 100 m of 4 inch hose – then sprayed out across the surface of netted salmon pens. The customer is now installing 4” and 2” stainless steel slurry eductors in multiple permanent installations.
