Since 1963, Fox Venturi Eductors have been installed to pneumatically convey bulk solids with no moving parts. Approval by the USDA in 1987 enabled Fox sanitary eductors to become extensively used throughout the food and dairy industries.

Fox Sanitary Eductors perform identically to standard (industrial) Fox eductors but are designed specifically for use in CIP (Clean-In-Place) systems in the food industry. To facilitate easy cleaning and inspection of internals, for avoiding both bacterial contamination and product cross-contamination, Fox food-grade, USDA-approved eductors include these key features:

• Highly polished internals, with polished and ground welds.
• No cracks, threads, corners, or 'dead spaces.'
• Tri-Clamp ( or other sanitary) end connections.
• No tools required for disassembly.

An Alternative to Sanitary Airlocks:

Airlocks are frequently selected for use in food processing systems even though they may not be the most appropriate choice. Consider these advantages of eductors:

• Cost - Food-grade airlocks typically cost 3 - 5 times the price of sanitary eductors.
• Housekeeping - Airlocks feeding positive systems inevitably produce blowback which creates dust, pest, and housekeeping problems. Blowback doesn't exist with eductors.
• Maintenance - Fox eductors require no maintenance. There are no seals to replace, no bearings to fail, no spares to stock.
• Metal Contamination/Safety - This is not a concern with eductors. There is no scraping or metal-to-metal contact. There is no safety hazard.
