Lowara 750 LV Vertical Expansion Tank (10 Bar)

The 750 LV litre vessel from Lowara incorporates a fixed Butyl diaphragm mounted in a mild steel shell. This method of construction eliminates any contact between the stored water and the steel shell of the vessel, and is therefore suitable for use with potable water.

The vessel is supplied pre-charged with air, but this pressure may require adjustment to suit the site conditions. This adjustment must be made with the vessel isolated from the system, and before filling with water. Air may be vented from, or pumped into, a Schraeder valve which will be found under a black plastic screw-off cover on the shell (sizes up to and including 500 litre) or on a side mounted flange (750 and larger). It will be noted that vessels of 60 litre capacity or larger are manufactured with connections at either end of the vessel shell.
