Fox maintains an up-to-date datbase of all installations made with Fox venturi eductors: Larry has been deeply involved in the design and engineering of Fox products for over 25 years:.

Liquid-driven mini-eductors are used in a huge variety of industrial applications — especially for replacing and eliminating expensive small pumps in corrosive, explosive, high purity, or toxic applications — including:. These off-the-shelf corrosion-resistant eductors are installed in hundreds of applications ranging from venting toxic hydrazine from fuel lines on the Space Shuttle after landing to circulating refrigerants in chiller systems at start-up.

Liquids Pumping Gas — Liquid driven mini-eductors are capable of entraining small amounts of gasses, but only if the discharge pressure is below about 2 psig.

Larry Fox has been managing Fox since This enables trials with varying motive flow rates, eventually yielding an optimized final design.

If the product conveyed is educyor or abrasive, blowback can cause extreme wear problems. Motive, Suction, and Discharge. These venturi eductor systems can be used to convey product at up to 15 tons per hour over distances up to feet.

Fox Liquid Eductors

And, of course, safety is simply not a concern with Fox eductors. We are a privately owned small business founded in Motive liquid flow rates range from 0. Retrofitting existing systems with Fox eductors can result in very significant improvements. Motive gas flow rates range from 0.

As with any conveying system, the three basic questions are: Discharge piping cannot be reduced after the eductor — and spray nozzles to create a high velocity jet cannot be installed downstream of a mini-eductor. Mini-Eductors are used in the same way as a pump in a process or system. Fox mini-eductors can be used to convey very small amounts of fine powders, over short distances, in carefully engineered systems — usually pilot or bench-top research applications.


Not only can internal geometry be changed to suit eductof conditions, but additional features can be added such as two to four suction ports, mounting holes, special end connections, electropolishing, UL-approval, passivation, oxygen cleaning, etc. Discharge pressure, discharge pipe size, and discharge pipe geometry are therefore critical to performance.

Our legacy as an aerospace company means we have the very highest standards for the equipment we build and ship. Feedback from customers often reveals five, ten, or even fifteen years of maintenance-free operation. Please visit our Case Study Centuri Page to request detailed application information about Venturi conveying systems in your industry. This often occurs with very fine, abrasive, fragile, or edjctor solids. Industry uses many different names for the products we supply as Fox Mini-Eductors.

Our proprietary computer models can enable us to design internal geometry per your fluids, flow rates and pressures, and then quickly modify existing stock components to assemble an optimized mini-eductor or prototype. However, Fox can quickly deliver optimized mini-eductors, with internal dimensions modified to meet your operating conditions in just 1 — 2 weeks.

Fox Venturi Eductor

This highly customized ss mini-eductor began as a quick-proof-of-concept prototype, with NPT ends, that Fox supplied in 2 days using modified stock components. Lou is extremely experienced in vacuum cooling and other applications in the food industry, and Fox is extremely lucky to have him available for start-up, trouble-shooting, and consulting visits with Fox customers. Fox Venturi Eductors are used to introduce bulk solids such as powders, pellets, flakes, and particulates into positive pressure conveying systems.

Fox Valve integrates forty years of venturi design experience with outstanding manufacturing capability. Click to Download Bulletin Use our CNC computer numerically controlled lathes to make production quantities in batches of 50 to pieces. Eductor systems often use one blower to drive many eductors, making for surprisingly simple systems when handling material from multiple outlets, as is common with dust tox or cyclones, as illustrated below.


How do they work? Fox Venturi Products Fox Valve has been the leading global supplier of venturi eductors and venturi transport systems for dilute phase pneumatic conveying of powders, pellets, and bulk solids since Please note that the eductor accomplishes work by compressing or pressurizing fluid from the suction port up to a higher pressure at the discharge.

We welcome applications that require critical engineering analysis, custom engineering, and in-house rox. The quotation will include all relevant operating data. However, instead of using electricity to drive a rotating impeller or compressor, the mini-eductor uses fluid mechanics to create suction with the energy stored in your flx fluid.

These are available both as: Successful testing then lead to supply of this electropolished mini-eductor with VCR and tube stub ends, for use in high-purity semi-conductor gas applications.

Even with free-flowing products, blowback can be a problem, causing bridging and housekeeping problems, or even an explosion hazard.

Fox Eductors, also referred to as jet pumps, enable the use of low ventuti air below 14 psig or 1 bar to be used to move powders, pellets, and bulk solids with no moving parts. These products are used to convey everything from apple bits to zircon sand in industries as diverse as educgor, cement, chemicals, power plants, and mines. A Fox Eductor is driven by a positive displacement blower package. For decades, many of the largest global integrators of analyzer and instrumentation systems have included Fox gas sampling mini-eductors in their analyzer solutions.

Designing with eductors from the beginning ensures the most reliable product feeding available. This is reflected in the brass liquid eductors we build for use in air conditioners, the skid-mounted steam ejector vacuum systems we build for refineries and food applications, the sanitary conveying systems we build for transporting milk powders, and all the other venturi products Fox supplies to dozens of industries including foundries, dairies, refineries, bakeries, plastic compounders, cement plants, mines, and NASA labs.
