Checking The Pump Inlet Filter

The Universal Pump Probe contains a filtering system to protect the
pump from particles and water in the sample air. If the filter becomes
clogged, the sample flow may be blocked, or and extra load may be
placed on the pump; therefore, check the filter regularly.
The frequency of checks should depend on amount of pump usage and
concentration of particles allowed to enter the pump. In dirty
applications, replace the dust filter every 200 hours.

Replacing the Filters

When replacing external dust and water filters, prevent any
dust or dirt around the filter housing from entering the pump
housing. Dust or dirt in the pump unit may impede pump
operation.

Probe Filter

The MSA sampling probe contains a filter to:
block dust and dirt
block the passage of water.
If the probe tip is accidentally submerged in water,the filter prevents the
water from reaching the internal pump. The filter is not designed to stop
other liquids, such as gasoline or alcohols.
