The maximum vacuum level-at the no-flow, or shut-off condition-is often not important. Many applications need to simply vent or exhaust vapors. What’s the deepest vacuum I can pull with an air ejector? However, as a general rule it is always best to maintain a constant motive gas flow rate and adjust the suction gas flow with a dedicated valve on the suction line.
In certain applications, and only when discharging to low pressure, this can work over a limited range. Can we control the suction gas flow rate by adjusting the Motive flow rate? Completely custom ejectors, for deep vacuum or higher discharge pressures may require 4 – 8 weeks – which can often be expedited with a rush premium. If your application has a low discharge pressure, the chances are good that components of stock ejectors can be quickly modified to become an optimized venturi jet for your specific application – and can ship in a week or less. How fast can we get one?įox has a large inventory of stock gas ejectors that are stored both assembled and unassembled, in line sizes from 1/2” to 6” in carbon steel, stainless, and PVC. This 39-foot-long air ejector has 42” flanges and was used to evacuate a high altitude test chamber.
