Round Transvectors® use a small amount of filtered compressed air to deliver a large airflow for a wide range of conveying, ventilation, drying and cooling applications. The high-flow, bladeless blowers don’t require machine guards and are especially useful for removing metal chips and scrap, ventilating fumes or smoke, and conveying small parts, pellets, powders and dust.
As a vacuum or blowoff device, these air amplifiers are more compact and less expensive than variable-speed blowers and fans, provide instant on/off performance, and operate at low noise levels to meet OSHA requirements. Round Transvectors® are easily mounted and, with no moving parts to wear out or break, are virtually maintenance-free. Used in ducted and unducted applications, Round Transvectors® are available in several sizes, in both aluminum and stainless steel, and can deliver flow rates from 32 to 2300 SCFM.
Applications
- Convey any material that can be moved in an airflow including grain, plastic pellets, sawdust, powder, capsules, metal chips, paper and cloth trim, lint, dust, small parts, stamping scrap and lead shot.
- Ventilate and exhaust welding, soldering and machine smoke, auto exhaust, plating tank fumes and other gases.
- Cool, clean or dry molded parts, castings, food products, etc.
- Weigh sort pharmaceuticals and other light materials.

All flows are at the standard factory setting. Flows are adjustable on the stainless models via
rotation of the outlet “barrel”. Flows are adjustable on the other models via shim substitution.
Reducer adapters available for inline configuration.

Significantly smaller and less expensive than variable-speed blowers or fans
In ducted applications, Round Transvectors can be used to transport metal chips and shavings, sawdust, powders, grains, small parts, and almost any material that can be conveyed in a flow of air. Simply calculate the total flow you will require and specify a model that will meet that requirement. A pressure regulator can be used to control the flow rate of material, or shims of various thicknesses are available to also modify air flows.
Stainless steel models are ideal for applications where purity, corrosion, abrasion or heat is a concern.
Stainless steel versions are fully adjustable simply by rotating the barrel of the outlet. A shoulder on each end of the Transvector will allow for mounting and clamping hose or tubing. For inline configurations, the following reducing adapters can be ordered:

| 997 | Reducer for Model #903 (Aluminum Body) 2 3/4” x 2.00” |
As a ventilating device, Round Transvectors are highly effective in drawing off welding and machining smoke, engine exhaust and other pollutants, as well as purging tanks and confined spaces of explosive or toxic fumes.
More Compact and Less Expensive than Variable Speed Blowers or Fans
In unducted applications, Transvectors deliver amplification ratios of 60:1, creating a powerful and concentrated flow of air for cooling or drying from a relatively small account of compressed air. Unlike motor-driven fans and blowers, Transvectors have instant on/off cycling capability for equipment and applications requiring intermittent vacuum, blowoff or conveying.
We incorporate the proven Transvector® amplification principle in our nozzle and jet designs. When compressed air enters the nozzle or jet, it fills a chamber with only one exit path – a .002” (.051mm) annular orifice. As air passes through this orifice, it accelerates to 1000 feet (304.8m) per second and entrains free surrounding air as it exits. The result is airflow volume up to 25 times more than the compressed air supplied.
