Water separator
To avoid unstable readings it is essential that the air supply to the mixing chamber is clean and dry. Jenway
recommends that a water separator be used with all flame photometers as when air is compressed,
condensation occurs. The amount of condensation will depend on the humidity in the air, so in high humidity
areas, water separators are essential. The water separator fits on the air-line between the compressor and
the flame photometer. This is where condensation forms. Any water collecting in the tube will cause
unstable readings and if it enters the instrument, will lead to the eventual corrosion of internal components
in the air-line.

Compressor
The compressor is a reliable, quiet air compressor of oil-less design requiring minimal maintenance. The
compressor is constructed from a lightweight but rigid aluminium extrusion and is housed in a protective
case to ensure maximum user safety and convenience. Load bearings are permanently lubricated and sealed
for the life of the compressor. A PTFE composition cup offers excellent sealing and wear properties. The
integral motor has its own cooling fan and is thermally protected against overload.
5.2.1 Specification
The compressor gives a supply of dry, clean and pulse free air at a pressure between 15 and 30 psi
(approximately 1-2 kg/cm
2
) at 6 litres/minute. There are two models available depending on the required
voltage.
