Material Conveying Generator (DF Series)
The DF Series of high flow material conveying vacuum generators provide a simple, reliable and cost effective method of in-line transfer of bulk materials, complex shapes, individual objects, selvedge.
The DF generator's unique capability to create instantaneous vacuum flow and high air velocity, combined with its straight-through, smooth bore design allows material to pass directly through the generator at high speeds without interference or clogging.
Simply regulate the input pressure to adjust and control the transfer speed. For maximum efficiency, the compact design allows close placement to the work area. DF Series material conveying generators are made of anodized aluminum and available in 17 standard models with inside diameters from 1/8" [6mm] to 4" [100mm].
Sizing the correct DF material transfer generator should take into account the material density, particle size, transfer rate required (kg/min), elevation and length of transfer line. For application assistance, please contact Vaccon Technical Support, or download the DF Series Application Installation Examples for application examples and typical configurations. Customers can send product samples to Vaccon to test at our in-house test facility where we will size the correct DF generator and send a video of the results.
Modified versions of the DF Series Material Conveying generators for specific applications are available. The DF 25-12-110-RI Aggregate Conveying generator is ideal for spraying dry and abrasive materials such as mineral fragments, stone dust, metal filings and ceramics.The DF 5-6-FD-ST8B Liquid Conveying generator can be used for field and mobile cleanup of liquids.

The -3 versions of the DF Series generators from DF 3-3 through DF 20-3 are no longer a stocked item. Consult the factory for availability.
To achieve equivalent performance of a -3 generator, simply regulate the air supply pressure down to approximately 40 PSI with the equivalent -6 model. For example, to achieve the performance of a DF 7-3, use a DF 7-6 with an air supply pressure of 40 PSI.

Notes:
- Custom threaded ends are available. For more details, download the DF Series Custom Threaded End Information PDF.
Please note, DF units with threaded ends are custom, and therefore not returnable. - Male and female threads can be ordered on opposite ends of the same generator, i.e. DF 5-6-TV50/MTE50.
- Tubing sizes specified in inner diameter (I.D.), based on polyethylene / polyurethane tubing with 1/16” [1.5 mm] wall thickness.
- Vaccon discourages the use of quick disconnect fittings on all connections.
Important Safety Note: When conveyng materials through plastic transfer lines, you must ground the transfer lines to dissipate the static charge that develops from the friction of the air and material flowing over the transfer line surface.
