3 Connecting and Operating the Equipment
It is recommended that the compressed air is treated prior to entry into the distribution system and also at critical usage points / applications.
Installation of compressed air dryers to a previously wet system could result in additional dirt loading for point of use filters for a period whilst the
distribution system dries out. Filter elements may need to be changed more frequently during this period.
For installations where oil-free compressors are used, water aerosol and particulate are still present, general purpose and high efficiency grades
should still be used.
A general purpose filter must always be installed to protect the high efficiency filter from bulk liquid aerosols and solid particulate.
Install purification equipment at the lowest temperature above freezing point, preferably downstream of after coolers and air receivers.
Point of use purification equipment should be installed as close to the application as possible.
Purification equipment should not be installed downstream of quick opening valves and should be protected from possible reverse flow or other
shock conditions.
Purge all piping leading to the purification equipment before installation and all piping after the purification equipment is installed and before
connection to the final application.
If by-pass lines are fitted around purification equipment, ensure adequate filtration is fitted to the by-pass line to prevent contamination of the
system downstream.
Fit drain lines from the coalescing filters directly to a condensate separator. If it is not possible to connect the drain lines directly to a separator,
the lines should be vented in to a condensate manifold (vented at one end) and then in to a single inlet of a condensate separator.
Provide a facility to drain away collected liquids from the purification equipment. Collected liquids should be treated and disposed of in a
responsible manner.
The lifetime of oil vapour removal filter elements is affected by the inlet oil concentration, relative humidity and temperature of the compressed
air system. Oil vapour removal elements will require changing more frequently than the equivalent coalescing element.
Models BAF010 - BAF015 are fitted with a bulk oil indicator. Both filter elements and indicator should be changed if the indicator is blue in
colour.
Note: This is a bulk oil indicator, it does not indicate filter element life.
