The Balston Vacuum Pump Exhaust Filter System
B
alston Vacuum Pump Exhaust Filters utilize Microfibre Filter Cartridges. The
filter cartridges capture the fine oil droplets suspended in exhaust air, and cause
the droplets to run together to form large drops within the depth of the filter
cartridge. The large drops are then forced by the air flow to the downstream surface of the
filter cartridge, from which the oil drains by gravity. This process is called "coalescing".
Since the coalesced liquid drains from the cartridges at the same rate that liquid droplets
enter the cartridges, the cartridges have an unlimited life when coalescing relatively clean
liquids, and they operate at their initial retention efficiency even when wet with liquid.
Filter Performance Characteristics
The Microfibre Filter Cartridges are specifically designed to cover vacuum pump
exhaust applications to achieve a retention efficiency of 99.9% at 0.1 micron with a low
flow resistance - less than 2 psi back pressure when wet with oil at the maximum flow
rating for the housing. The two stage filter cartridge structure minimizes the possibility of
carryover of coalesced oil, and the all-inorganic composition is completely resistant to all
lubricants and virtually any chemical found in vacuum pump exhaust. The maximum
temperature limit for a filter assembly is determined by the elastomer seals or plastic
materials in the system.
The filter cartridge is permanently sealed into the housing. The entire unit is
disposable. Pressure relief filter tube retainer is not available in these models.
NW-25 Adapter fittings for Alcatel Vacuum pumps are also available.
