Our commitment to quality and customer satisfaction has established us as a trusted supplier of vacuum ejectors, with a robust client base that includes some of the world’s leading companies in the chemical, pharmaceutical and food processing industries.
A high-pressure motive fluid expands through a precision nozzle, converting pressure into a high-velocity jet. This jet entrains the process gas in the suction chamber, drops the local pressure and carries the combined stream into the diffuser, where velocity is recompressed back to discharge pressure.
With no moving parts, the entire process is mechanical and continuous, delivering deep, stable vacuum with minimal maintenance even on corrosive or abrasive duties.
Result: reliable suction pressures from atmospheric down to 0.01 mbar across single and multi-stage configurations.
A complete family of ejector technologies, engineered and built in-house for diverse process duties.
The motive fluid is a non-compressible liquid, generally water. Without heat energy and driven by a single-stage centrifugal pump, nozzle-tip velocity stays relatively low, which suits steady non-condensable loads where steam is not preferred.
High-pressure motive steam expands through a precision nozzle to generate reliable vacuum with no moving parts, making it the workhorse of deep-vacuum duty. Combination systems connect a liquid jet ejector suction to the last steam-stage discharge to reach very low absolute pressures.
Usable for either critical or non-critical flow, though it is typically optimised for one set of design conditions. Its compact size is the key advantage, and it is generally chosen where very large compression ratios are required.
Shail Vac’s multiple-nozzle design places one nozzle at the centre with the remainder spaced evenly around it. For the same conditions, this raises efficiency and shortens length compared with an equally rated single-nozzle unit.
Ejectors can be operated with different motive fluids: steam, air, organic vapour, other gases and their mixtures.
No moving parts: simple, reliable, rugged and trouble-free with minimal maintenance
