VFD - Prefilter with Pressure Controller

The VFD is a compact pre-filter including integrated pressure regulator but without built-in heat control. The VFD can be operated using any common heat controller, or it can be integrated in an IAG measuring unit.

The VFD is a compact filter pressure regulator, offering an alternative to an LFD line filter with pressure regulator. Lacking a heat control of its own, it is particularly suitable for integration in existing systems, with parameterization and monitoring being performed via the control system.

The backflushable NO pressure regulator reduces inlet pressures of up to 6 bar to an outlet pressure of max. 250 mbar. Naturally any IAG filter cartridge can be fitted to the VFD. All IAG devices can be supplied with pin assignment, gas connectors and temperature sensor type according to customer requirements.
