Technical notes
1.

Direction of flow is outside to inside through the element.

2.

Filter elements should be replaced at least every 6 months.

3.

Differential pressure gauges (65DPG250B) are fitted to all models as standard. Volt free contact options are available - see price guide.

4.

Manual drain valves (MDVE25) are fitted to all models. Sterilisable glass drain flasks are supplied as standard, 100ml for models A3052MV
to A3101MV and 250ml for models A3102MV to A3303MV.
Threaded connections are Rp (BSPP parallel) to ISO 7-1 or NPT to ANSI/ASME B1.20.1 if supplied within North America. Rc (BSP Taper)
to ISO 7-1 also available.
For NPT connections, add the suffix ‘N’ e.g. A3052NMV. For Rc threads add the suffix ‘C’ e.g. A3052CMV.
