Proper vacuum pump management is essential to ensure the longevity of Particles Plus® internal-pump instruments. To get the most out of your vacuum pumps, please note the following:

Life Expectancy 2.83 LPM (0.1 CFM)
• Pumps running continuously: 1 year
• 1 minute sample, 4 minute hold time: Up to 5 years
• 1 minute sample, 9 minute hold time: Up to 10 years

Life Expectancy at 1.2 LPM
• Pumps running continuously: 2.5 years
• 1 minute sample, 4 minute hold time: Up to 12.5 years
• 1 minute sample, 9 minute hold time: Up to 25 years

Factors affecting expected performance
• Elevated temperatures will reduce life expectancy. Running at room temperature or below is optimum.
• Adding a restriction to the inlet (i.e. long tubing) will make the pump work harder and reduce life expectancy.
• Working in very dirty air will load the internal filters and make the pump work harder. If this is your condition there are options for most of our instruments to have the exhaust filter mounted externally for service.

Proper care and management of your internal vacuum pumps will ensure optimum life expectancy and performance.
