Air-Operated Vacuum Generator Technology “We Will Build You A Vacuum Source...” Flexibility of Design, Perfect for OEM Applications With high tech design, precision manufacturing, and quality testing, we can easily and economically change configuration, material, connections and performance to meet your exact specifications. Air-Vac offers four basic pump designs (AV, TD, MF, UV), with each providing a unique advantage. 50 Years Specializing in Air-Operated Vacuum Generator Technology. Air-Vac has designed and manufactured a broad range of vacuum pumps because there are advantages to each design and one design is not suitable for every application. Vacuum applications fall into the following categories: Vacuum Force Generators AV, AVR, RAV, MF & UV Models: Used for applications where the primary concern is the development of a high vacuum level and is measured in inches of mercury (“Hg). Used with vacuum cups in pick-and-place applications. For removing air or gases from process vessels, chambers, tanks or other closed systems. Vacuum handling and positioning of parts, leak testing of various systems, vacuum forming of sheet metal or plastic parts, and labeling, packaging and paper feeding machinery. The UV “Ultra-Vac” design provides near perfect vacuum of 29.7”Hg. Used to evacuate chambers, degas liquids and in other processes requiring vacuum levels of 1/4”Hg absolute (8 Torr). Used as a first stage pump in applications requiring high vacuum reducing operating time of expensive high vacuum pumping systems. Corrosion Resistant Stainless Steel Generators Vacuum Flow Generators TD & TDRH Models: Used where the primary concern is the induced flow of atmospheric air and relatively low vacuum levels. Pumps are designed for dynamic performance and are measured in cubic feet per minute (scfm). In addition, the straight through vacuum passage allows material to pass directly through the generator with no reduction of vacuum flow. Ideal for transporting or conveying solid materials in-line, vacuum removal of machined chips and loose scrap in fabricating dies, venturi wipes for wire drying, thread removal in textile machinery, air sampling in gas analyzing systems, and mixing of liquids and gases. The exhaust flow is a combination of compressed air and vacuum flow and can be used in various applications including: drying and air cooling systems, fluttering and handling of paper, opening bags and cartons, and air blowing systems for removal of parts, scrap or foreign matter. HAVRSS, HAVSS & TDSS Models: Used in a variety of industries and applications including: transport of abrassive materials, used in food processing because they withstand the aggressive chemicals used in sanitary wash downs. Having no electrical connections, they can be easily installed in hazardous explosion-proof areas, and used in high temperature applications.

The AV Single Stage Design is two piece construction, manufactured from aluminum and brass. It produces vacuum levels up to 27.5”Hg. Specifications Vac Vac Air level flow used Hg “H” versions produce HIGH vacuum levels. Vacuum Flow Rates to 12.5 scfm. AVR038H • AVR Series are small and easy to install with a vacuum flow to 1.7 scfm • AV Series are intermediate in size with a vacuum flow to 6.8 scfm • RAV Series are larger in size with a higher vacuum flow up to 18.2 scfm Compressed air flows through a small circular opening to generate a high velocity. This air expands, resulting in...

The TD Single Stage Design was primarily designed to provide a straight through vacuum passage to allow the transport of solid material with no reduction of vacuum flow. Specifications Vac Vac Air level flow used Hg “H” versions produce HIGH vacuum levels. Vacuum Flow Rates to 10.9 scfm. TD110H Compressed air flows through a small annular opening to generate a high velocity. This air expands into an unobstructed vacuum passage, allowing solid material to flow through the pump with no decrease in vacuum flow. “M” versions produce MEDIUM vacuum levels. Vacuum Flow Rates to 33.0 scfm, but with...

The MF Multi Stage Design provides high initial vacuum flow for fast evacuation. Multiple vacuum chambers insure minimum air consumption, providing low operating costs. Specifications Vac Air flow used scfm Energy from a single flow of high velocity air is used to maximum efficiency. Flow is forced through three venturi sections. Vacuum is created in three separate chambers. A common vacuum manifold connects to the three vacuum chambers. The result is high vacuum flow with low air consumption and fast evacuation. MFP Series - “H” version produces HIGH vacuum levels (27.2”Hg) and vacuum flow...
