- Plan the nozzle pattern on the tables to be converted to air tables.
- Make certain that there are no obstructions on the underside of the table such as ribs, wiring, junction boxes, legs, etc. in the area where the nozzles are to be inserted.
- Mount adequate nozzles under the moving load to provide a cushion of air upon which the load will float based on size and weight of load. Nozzles are typically placed on 6" centers.
- Nozzles should be located to provide full coverage of the moving load while allowing for adequate edge clearance.
- Since plant air represents an expense it is desirable to minimize any air loses in your air handiling system. To significantly improve the load bearing characteristics of a system and reduce air consumption at the same time, put a spotface approximately 2" to 4" diameter by 1/64" (0.020"); deep around each nozzle and mount the nozzle slightly below flush with the base of this spotface.
The net effect is that nozzle now supplies a lift pad of air 2" to 4"in diameter as compared to the lift pad of 1" diameter around the head of the nozzle itself. Since area varies as the square of the diameter, this lift will be 4 times (2" diameter spotface) to 16 (4" diameter spotface) as great as without it, and the system air pressure may now be reduced accordingly. This will significantly reduced the air consumption of the system.
Maximum of 25 nozzles per regulator. For larger tables use multiple regulators (multiple zones).
