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.
5.1.1 Features
1. Available in two sizes: large (normally recommended) (part code 500 177) or small (for
areas of low humidity) (part code 500 176).
2. Complete with all parts to connect to the flame photometer.
3. Provides optimum performance in minimum space.
4. Provides effective liquid and solid separation.
5. No maintenance required.
6. Finger operated plungers for easy draining.

Compressor

The 8515/8516 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 Teflon
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 8515/8516 compressor gives a supply of dry, clean and pulse free air at a pressure
between 14 and 30 psi (approximately 1-2 kg/cm
Model 8515
Part Code 535 001
Voltage: 230V, 50/60Hz
5.2.2 Installation
The compressor should be positioned on a stable surface within 2 metres of the PFP7.
Connection to the PFP7 should be carried out as follows:
1. Ensure the power supply to the PFP7 is switched off.
2. Connect the air tubing (supplied with PFP7) to the 8515/8516 outlet nozzle and secure
with a hose clip.
