High Volume Air Amplifiers for Many Applications


High Volume Air Amplifiers for Many Applications


Round Transvectors are ideal for conveying any material that can be moved in an airflow and for removing fumes and scrap.  Since air amplifiers move large volumes of air using only a small amount of compressed air, they are economical to operate.


Air Amplifiers Applications:


Round Transvectors are used in both ducted and unducted applications. In ducted applications, they are used at flow rates up to 2400 SCFM (67920 SLPM).  Transvector Air Amplifiers are excellent for ventilating, air conveying, drying and cooling.

Transvector's wide range of applications include:

  • Conveying any material that can be moved in an airflow, including grain, plastic pallets, sawdust, powder, capsules, metal chips, paper and cloth trim, lint, dust, small parts, stamping scrap and lead shot.

  • Ventilating and exhausting welding, soldering and machine smoke, auto exhaust, plating tank fumes and other gases.

  • Cooling molded parts, castings, etc.

Transvectors General Information

The Air Supply


Compressed air consumption through the Transvector is proportional to the absolute inlet pressure. Therefore, the compressed air consumed at 50 PSIG (3.4 Bar) or 65 PSIG (4.5 Bar) is half of that consumed at 115 PSIG (7.9 Bar) or 130 PSIG (9.0 Bar). By controlling the inlet pressure, it is possible to vary output flow over a wide range-duplicating the functions of complex variable-pitch and variable-speed fan systems. Transvectors have no moving parts and do not require complex controls. In automated systems, the pressure regulator can be pilot operated and controlled from a remote location. Since airflow requirements of an application are usually not known, we recommend the use of a pressure regulator. This will ensure that the Transvector is set to only consume the required amount of compressed air.


For Transvectors to operate properly, they must be kept clean. Condensation in compressed air lines creates rust and dirt. Use a 5-micron filter separator to remove foreign material from the lines. Failure to use a filter will cause clogging in a matter of minutes. Transvectors have no moving parts. If the air is properly filtered and the filter elements are regularly changed, no maintenance should be required. Change the filter elements and inspect the inside of the Transvector about every six months for dirt, wear and contamination. Remove the four screws that secure the suction inlet to the body and carefully lift out the aluminum shim and inspect it and the nozzle area for accumulated dirt. If dirt is observed, increase filter changing frequency.

Ducting Restrictions

Any restriction placed in the outlet or at the suction inlet of a Transvector will reduce its performance. Transvectors will work against small dusting back pressures at either end. They are designed to anticipate some back pressure-up to 2" (5.1 mm) of water column. In many applications, the outlet of a Transvector will be connected to ducting to carry smoke or fumes away. Design ducting for total flow resistances of less than 2" (5.1 mm) water column. This will prevent major reductions in flow performance.


When venting a large tank or other closed space where workers are involved, consider the nature of the fumes to be removed. Whether they are heavier or lighter than air will determine how the Transvector should be used. The following suggestions are for a large tank with a hatch at the top. For heavier than air fumes use the suction feature of the Transvector. Place it low in the tank in a remote corner. Attach a flexible exhaust tube to the Transvector outlet and run it out of the hatch. As fumes are vented, fresh air will flow in the hatch. For lighter than air fumes, place the Transvector outside the tank near the hatch. Attach flexible tubing to the Transvector outlet and run it down into a remote corner. As the Transvector pumps fresh air into the tank, the lighter fumes will be forced out the hatch.


Transvectors are ideal for conveying light parts with air. Most materials such as sawdust, grain, plastic parts and resins, soap flakes and so on work well in Transvector conveying systems. The material should be dry, light and finely divided.

Material flowing in a tube will slow because of loss of velocity in the tube. This is especially true in blow conveying where the material is sucked into the Transvector and blown out into a tube connected to its outlet. As the conveyed material slows down, it can bunch together causing pressure drops and blockage. Use blow conveying on short runs.

Vacuum conveying is preferred on long runs. In vacuum conveying, the material is drawn into the remote end of the tube and moves toward the Transvector. Air in the tube moves faster as it approaches the Transvector, preventing blocking and bunching.

Another important consideration is static electricity. Conveying applications can build large static charges causing sparks and a possible fire. Use grounded metal piping to eliminate charge build-up when flammable materials are nearby.

Since large volumes of air are used in Transvector air conveying, the material arrives at the end of the run in a rush of air. Care must be taken to separate the material from the air. If the stream is injected tangentially into a cylindrical receptacle, it can be settled out in a quiet zone at the bottom of the container. The container must be vented.


A common use for Transvector Airflow Amplifiers is smoke and fume removal from welding operations and solvent tanks. Because of the unusually quiet operation of the Transvector; it can be placed near workers. Its output can be ducted through flexible tubing to a window or an existing exhaust duct over 50' (15m) away.

Always use a filter and pressure regulator. Start with a very low pressure, about 5 PSIG (0.34 Bar), and run the process. Increase pressure slowly until all of the smoke or fumes are removed. Lock the regulator knob at this point.


Transvectors can be used to cool hot parts when they are located in a relatively cool area. The Transvector's capacity to cool the parts is directly related to the total airflow directed at the part and the difference between the room and part temperatures. Transvectors do not contaminate parts with coolant.
