Inline filter for dirty and harsh environments <br />Dimensions of <br />E700-FILASSY <br />180mm height x <br />120mm width <br />Airflow In <br />Installation <br />The E700-FILASSY should be installed as shown in the figure on <br />the left. Note the following considerations: <br />>0.5m straight <br />. Mount the filter vertically above the detector inlet. <br />pipe length <br />before any <br />0 Standard 25 mm or 1/4" pipe' can be connected to the filter <br />bend <br />inlet. The filter outlet, which has a standard air sampling <br />pipe diameter of 25 mm, connects to the VESDA detector. <br />■ The air sampling pipe input and output must both have a <br />minimum 0.5 metres (1.64 ft) of straight pipe before any <br />bends and detector connection. <br />■ Each sampling pipe requires an individual filter assembly. <br />■ The filter lid has four options for pipe attachment. However, <br />only one should be used and the other three must be firmly <br />blocked with the plugs provided with the filter. <br />■ The filter is supplied with two choices of sockets to <br />>0.5m straight <br />accommodate 25mm and 1/4" sampling pipes depending on <br />pipe length <br />the your requirements.

A Tee <br />junction is used to connect a water trap. The water trap <br />should be at least 0.5 metres (1.64 ft) away from the filter <br />assembly. The angle of the filter assembly allows the <br />condensate to travel back towards the water trap. <br />Both dimensions areinner diameter. <br />Page 2 of 3 <br />
