Start with the decision you need to make. These guides explain how to compare vacuum equipment, check the figures in a datasheet and give Girovac the information needed for a useful quotation.
Compare flow and pressure
Understand pumping speed, end vacuum and operating conditions before comparing models.
Choose a backing pump
Check gas load, permitted backing pressure and roughing duty for a high-vacuum system.
Dry claw or rotary vane?
Compare MIL’S SIRELLA and EVISA using model-specific pressure and maintenance requirements.
Identify the right vacuum oil
Record the current grade and check chemistry, viscosity conditions and equipment approval.
Plan a central vacuum system
Define simultaneous demand, receiver and control requirements, then choose suitable measurement.
Choose a gauge and calibration scope
Compare pressure references and technologies, check interfaces and specify useful calibration points.
Have a model in mind?
Use the vacuum equipment catalogue to browse by brand or technology. Select “Compare” on up to three products to view their listed specifications together. Read the gas, frequency, pressure and test conditions alongside each value.
Replacing an existing pump?
Start with the full model reference and nameplate. Include the electrical supply, connections, controls, process gas and duty cycle. A similar pumping-speed figure does not establish that a replacement will work in your installation.
What to send for selection help
- Target working pressure and whether the duty is continuous or intermittent.
- Required gas flow, or vessel volume and required evacuation time.
- Process gases, vapours, particles and contamination requirements.
- Existing equipment, power supply, inlet and exhaust connections, cooling and available space.

Check the source behind the specification
The linked guides include manufacturer references where model-specific figures are used. Check the current documentation for the exact equipment and version being ordered. A manufacturer’s example or test result is not a guarantee of performance at your chamber.
Find equipment for your application
Explore composite processing, laboratory vacuum, vacuum holding and CNC, or central vacuum systems. Each guide connects the process requirements with pumps, measurement and accessories.
