Description

To ensure long, trouble-free service, Expo’s purge systems require good quality instrument quality compressed air. Our specifications are as follows (In line with: BS ISO 8573-1: 2010):

Particles per m³:     0.5 micron: < 20,00;  0.5 – 1.0 micron: <400;  1.0 – 5.0 micron: < 10

Oil per m³:              <0.1mg

Humidity:                Dew point at least 10°C below ambient. Never greater than 3°C

In cases where the air supply cannot be guaranteed to continuously meet this specification, Expo recommends the use of an additional in-line filter unit to pre-clean the purge air.

The system comprises a stainless-steel enclosure with two parallel filter lines. Each filter line can be isolated and blown down for maintenance or change-out, while maintaining flow through the other line to ensure 100% purge system and motor uptime.
