Aether Series Rotary Vane Vacuum Pump
3.2 Gas Ballast
The controllable gas (generally dry air at room temperature) is admitted into the pump chamber. It is mixed with pumped vapor during the gas compression process. This increases the percentage of non-condensable gas such that the partial pressure of the vapor being pumped, is below its saturated vapor pressure when the exhaust valve opens. The vapor is then discharged from the pump without liquefaction. The more vapor contained within the pumped gas means the more air is required (refer FIG.2 Gas Ballast Valve).
3.3 Accessories
To ensure the stability of the pump it is recommended that genuine spare parts and accessories provided by the manufacturer be used. Should further information be required please contact serviceusa@hollandgreenscience.com

8.2 Connection to the System
- For the pump’s installation site and positioning, consider convenience of access to the connections for installation, maintenance, disassembly, and electrical connections as well as good ventilation clearance.
- Ensure the power supply is disconnected prior to commencing connections, repairs, or maintenance activities.
- Set up on a flat, stable, and firm surface
- Ensure not to obstruct the ventilation of the motor to avoid fire and burn hazards caused by abnormal temperature rise.
- The pump must be operated at an ambient temperature between 10 – 40℃
- The length of the connecting line between the pump and the vacuum system needs to be as short as possible.
- The diameter of the connecting line is required to be the same as that of the intake port
- The exhaust line should be laid so that it slopes down to prevent condensate from back streaming into the pump and contaminating the oil.
- Drain the oil from the exhaust line periodically to avoid blockage of the exhaust line.
If the exhaust line slopes up, the installation of a condensate trap is necessary. - Check for connection leakage between the pipe and the flange.
- Vacuum sealing tightness is essential to achieve ultimate vacuum.
- Check the oil level prior to start up and each operation before running.
- Do not operate the pump without oil or if the oil level is low. This will result in pump failure.
- Check there is no oil leakage from the pump to prevent potential slip hazards caused due to oil spillage.
- Running the pump in an incorrect rotation of the motor may cause pump failure.
- Ensure the gas flow at the exhaust port is not blocked or restricted in any way.
Check the exhaust line is not obstructed by deposits before start-up. - The exhaust pressure shall not be 1.15 bar higher than the absolute pressure (relative pressure 0.15 bar) but not be lower than atmospheric pressure
- Oil must be added as outlined prior to start-up of the Pump.
- The exhaust passage must be unimpeded during operation. Ensure the gas flow from the exhaust port is not blocked or restricted in any way.
- To pump condensable gases only use the pump to do so if a gas ballast is installed.
- When pumping a small amount of dust and condensable gases, the installation of corresponding filters is required. Without filters, a sharp drop in performance or pump failure may occur.
Operating Instructions
Note: High Temperature Hazard – Do NOT touch the pump surface! The surface of the pump becomes very hot during operation.
9.1 Initial Start-Up
Ensure the gas flow at the exhaust port is not blocked or restricted in any way.
Do NOT start the pump if the exhaust port is blocked.
Excessive or insufficient oil will decrease pump performance or even cause malfunction. The pump must always be stopped prior to adding oil.
The oil level must be maintained between the position of MAX and MIN of the oil sight glass
9.2 Inspection and Maintenance
All checks and maintenance must be performed by a qualified trained technician in accordance with local safety rules and regulations.
If hazardous substances are present, firstly determine the hazard and then follow all appropriate safety procedures. If the potential hazard still exists, the pump must be decontaminated prior to proceeding with any maintenance.
| Content | Operation | Interval | Remarks |
| Oil Level | Visual Inspection | Every (3) three Days | |
| Oil Color | Visual Inspection | Every (3) three Days | |
| Pump Noise | Acoustic Inspection | Every (3) three Days | |
| Pump Vibration | Visual Inspection | Every (3) three Days | Check the pump feet / feet bolts in case of abnormal vibration |
| Pump Temperature | Thermometer | Every (1) one Week | Check and clean the fan of the pump Check and clean the motor of deposits |
| Seal & O- ring | Visual Inspection | Every (1) one Month | Replace if necessary |
| Dirt Trap | Visual Inspection | Every (1) one
month |
Check and clean the foreign matter. Dry with compressed air |
9.3 Pumping Non-Condensable Gases
To close the gas ballast to pump non-condensable gases, set the gas ballast valve to position C, The ultimate pressure will rise (loss of vacuum) once the gas ballast is opened.
9.4 Pumping Condensable Gases and Vapor.
If the vacuum system contains a small amount of condensable gas, open the gas ballast valve, set the gas ballast to position I or II and keep the pump running for at least 30 minutes to pump the condensable gas effectively.
If the pump operates at low temperature, condensable gas may be dissolved within the pump oil.
The oil may be emulsified or deteriorated which will affect the pump performance and can even cause corrosion of the pump body.
The rise of the oil level during pump operation is a sign that of condensable gas is contained within the vacuum system.
Keep the pump running with the gas ballast open and the intake port closed until all gases are dissolved within the oil and removed.
9.5 Oil Level Checks
1) The oil level must always be maintained between the MAX and MIN positions.
Add oil when the oil level is lower than MIN position MIN and discharge oil by removing
the oil drain plug refer FIG.1 when the oil level is above MAX position.
2) Check the oil colour. Replace the oil if the colour is other than clear and transparent.
9.6 Checking Pump Noise
The pump noise should be continuous and stable during operation.
9.7 Oil Changes
- Change the oil only when the pump is switched ‘OFF’ and cooled down.
- Remove the oil drain plug and drain the used oil into a suitable receptacle. When the flow of oil stops, screw on the oil drain plug, checking the O ring.
Remove the oil fill plug and fill with fresh pump oil - After completing an oil change, handle and store the used oil in an assigned container in accordance with your local relevant environmental laws and regulations.
9.8 Intake Filter and Anti-Suck Back Valve Checks
Regularly clean the filter by using compressed air.
Check the seal position of the anti-suck back valve for cleanness, damage, hardening and height.
9.9 Fan Cover and Motor Fan Checks
Regularly clean the fan cover.
