Dirt Tolerant Venturi Vacuum Pumps

The VDF & FDF Series are unique Vaccon innovations that place the vacuum port and exhaust path inline making a straight-through venturi vacuum pump. These compact pumps offer high flow rates up to 120 SCFM [3400 LPM] and high vacuum levels up to 25"Hg [847mbar]. Developed for extremely dirty and dusty environments such as foundries, refractory and bagging operations, VDF & FDF pumps don’t clog, lose suction or require a vacuum filter.
VDF Series Vacuum Pumps Are Ideal For Use In Applications In Environments Containing Heavy, Loose Particulate. The VDF Series Is Variable, Making It The Ideal Vacuum Pump In Applications That Do Not Have A Regulated Air Supply Or Undefined Vacuum Requirements. VDF Series - Variable Thru-Bore Vacuum Pumps

VDF pumps are field-adjustable allowing you to regulate the vacuum flow and vacuum level to meet your application requirements. This maximizes energy efficiency by consuming only the compressed air necessary to do the job. A pressure regulator is not required as the pump can be tuned to operate at any pressure above 50 PSI [3.5 BAR].
FDF Series Vacuum Pumps Operate With A Fixed Vacuum Level And Are Ideal For Use In Applications In Environments Containing Heavy, Loose Particulate. FDF Series - Fixed Thru-Bore Vacuum Pumps

The FDF Series offers the same inline, dirt tolerant design as the VDF Series without the adjustability. The FDF Series have a “fixed” performance level. The FDF Series pumps are set to generate the maximum vacuum level [25"Hg/847mbar] and maximum vacuum flow of the comparable VDF Series pump.
