Filter candles in filter machines are subjected to temperature of 80 deg to 90 deg C. These temperatures

tend to weaken the inter winding bonds of the filter element. The condition is worsen if core of the filter

element is of plastic/polypropelene (PP), as these filter elements also lead to deformation fter 75 deg C

temperature. However, PP yarn or nylon yarn do not absorb moisture and are better recommended for

wet applications. Hence a blend of SS core with PP yarn/Nylon yarn ensues good results in filtration.

It is of utmost important that Vacuum pump oil parameters like vapour pressure, viscosity are

maintained at varying operating temperatures of vacuum pump. These parameters are crucial for

deciding vacuum pump performance. Genuine vacuum pump oil recommended by pump OEM, are able

to deliver better performance of vacuum pump under running condition. Oils manufactured by pump

OEM, say LEYBNOL, manufactured by Oerlikon Leybold, have good blending of chemicals to preserve

the oil properties under different working conditions. Such chemically blended oils demonstrate good

performance in chemical environments.

Vacuum pump oil is often contaminated in wet applications, like drying. It becomes therefore vital to

maintain oil quality in order to expect continuous vacuum pump performance. Continuous monitoring of

oil quality and quantity can save over cost of replacing the vacuum pump. It is highly recommended to

use genuine oil in the vacuum pump as recommended by the OEM.
