3 Things To Consider When Choosing the Right Vacuum Technology
In today’s modern manufacturing World, vacuum technology plays a critical role in just about every industry. From food packaging and plastic extrusion to chemical distillation and woodworking router tables … all of these applications, and many more, simply wouldn’t be possible without vacuum. This means that choosing the right type of vacuum pump to fit an application is extremely important for not only the efficiency of the process, but the quality of the end product. Unfortunately, it’s common to assume that generating reliable and efficient vacuum merely consists of plugging in the vacuum pump and letting it drop to the required level – so the type of vacuum technology isn’t important, right? Wrong!
Important Things To Remember When Choosing the Right Vacuum Technology for Your process
There are three key factors to remember when researching and choosing the proper vacuum pump for your process: how the vacuum pump will impact the application and vice-versa; what the application’s vacuum requirements are; and the complete cost of ownership.
1. Impact of Process on Pump & Pump on Process.
It stands to reason that the type of pump you choose will impact your application, just as your application will impact the pump! For example, if you are selecting a pump for an oil-free application, such as pharmaceuticals or food packaging, then choosing an oil-sealed pump wouldn’t be the right decision.
| Pump Impact on Application | Application Impact on Pump |
| Pump vibration | Dust/debris from process |
| Oil emission (if an oil-sealed pump) | Mechanical movements & vibrations |
| Noise, heat, and particle emissions | Gases/other mixtures in process |
| Energy consumption |
2. Vacuum Level Requirements.
Different applications require different levels of vacuum, and different vacuum pumps pull different pressure levels. With this in mind, knowing which vacuum level is required is vital to selecting the right pump technology. For instance, selecting a liquid ring pump that operates only to 28-29" of vacuum would not be suitable for a process that requires good gas flow at less than 1 torr. You should also consider whether or not your vacuum pump requires a consistent pressure level to be held, or whether it’s focused more on the pump-down process.
3. Cost of Ownership.
This includes both the initial capital costs of purchasing the vacuum pump, as well as the costs of servicing and maintaining the vacuum pump over its lifetime of use. For example, certain pumps, such as a vane pump, might require more maintenance because of consistent vane replacements – while the maintenance costs on oil-sealed rotary screw pumps could be much lower. Saving energy, reducing the frequency of oil changes, and having maximum pump availability due to non-wearing points are all elements to consider when looking at pump costs.

Vacuum, the invisible force, is indispensable in industrial production facilities around the world. When an industrial application requires a
clean environment or pressure below atmospheric levels, a steady supply of vacuum is needed. Our vacuum products are the starting point to
providing a total vacuum solution for dedicated point-of-use machines and central vacuum systems.
Claw Pumps
The Ash Air range of rotary claw vacuum pumps is the best alternative to rotary vane pumps. A vacuum claw pump is virtually zero maintenance and compared to rotary vane pumps can work at vacuum levels of 400 to 1000 mbar without overheating. Rotary claw vacuum pumps are the best choice for CNC guided wood routers.
The Atlas Copco DZS series are mono claw, dry vacuum pumps that offer simplicity, robustness, efficiency and contaminant handling capability.
Atlas Copco vacuum pumps have always offered lower lifecycle costs, higher performance, less energy consumption and easy maintenance. Now, with the DZS VSD⁺ intelligent vacuum pump, you get that and much more. Think about intelligence, optimization, a plug & play pump, digitalization and a mobile app.
Liquid Ring Pumps
The Ash Air range of humble liquid ring pumps is still the most reliable form of large volume vacuum generation available today. These liquid ring pumps are simple to use and very reliable, and the best option when sucked air contains a large amount of saturated gas.
Pompetravaini liquid ring pumps have a low noise level and water flow, a stainless-steel impeller, reliable suction valves, and a compact installation. We offer Atlas Copco LRP VSD+ intelligent liquid ring vacuum offers superior vacuum performance and connectivity. It provides optimum energy efficiency along with low operational and maintenance costs. Its ease of use, integration into existing processes and centralization capabilities make this a truly unique liquid ring vacuum pump.
Contact us today to find out more about our range of liquid ring pumps.
Rotary Vane Pumps
Dry and oil-sealed vane vacuum pumps are robust, affordable and easy in maintenance. You can use DVP vane pumps for wide range of application, for skin packaging, holding, lifting, thermoforming.
We offer the Atlas Copco GVD series of 2-stage oil sealed rotary vane vacuum pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapor handling capabilities with quiet operation.
Also, the Atlas Copco GVS 16-630 A series operates according to the proven oil-sealed rotary vane principle that has been successfully used for many years in all general vacuum applications of industry packed with innovative features that ensure the highest possible performance at the lowest possible lifecycle cost.
At Ash Air we pride ourselves on supplying quality, reliable rotary vane vacuum pumps to our customers, with industry-leading servicing and spare parts for all brands. We offer 24/7 nationwide support with experienced engineers on hand to help when and where you need it.
