7.4.6 Outlet mist-filter (clean applications)
The outlet mist-filter (see Figure 8 , item 3) collects the oil contained in the oil-mist forming part of the discharge
gases. You can monitor the level of oil trapped in the filter, through a sight-glass. This mist-filter must only be used
for clean applications. You can return the trapped oil to your pump using the oil return kit. The mist-filter is supplied
with two ISO40 ‘C’ clamps, ISO40 elbow, two 40 mm co-seals, bolts, washers, mounting bracket and studs.
7.4.7 External oil filter
The external oil filter (see Figure 8 , item 2) is a free-standing filter. You can choose between two types of oil-filter.
The ‘A’ series uses an activated earth cartridge which provides chemical cleaning of the oil by removing acidic and
other aggressive contaminants. The ‘M’ series uses a pleated paper cartridge which does not provide chemical
filtering but removes abrasive particles down to 0.5 microns. You must check that the external oil filter you choose
is suitable for your application.
7.4.8 Solenoid-operated gas-ballast control valve
The solenoid-operated gas-ballast control valve (see Figure 8 , item 5) gives you automatic or remote control of gas-
ballast. You can connect the valve to shut off gas-ballast when the pump is switched off and so prevent air from
returning to the system.
7.4.9 Thermostatic control valve
The thermostatic control valve (see Figure 8 , item 6) promotes rapid pump warm-up and ensures optimum running
temperature by controlling cooling-water flow rate. This reduces water usage and running costs and significantly
improves vapour pumping performance.
