Oil for hydraulic guards

A102 oil is used for our pallet vacuum pumps but is also commonly used as a fluid with hydraulic guards mounted on glove boxes with gas purifiers.

The recommended oil is a high quality mineral oil with low saturated vapour content. For specific applications, it is possible to use oils with different properties.

The oil level of a hydraulic guard should be checked regularly. Correct oil level protects an airtight speaker from extremes of pressure. The advantage of an oil bath is that it traps particles from the atmosphere of the glove box. For this reason, it is recommended to replace the oil bath as soon as there is pronounced oil colouring or at least every 3 years.
