VFH-PRE-FILTER HEATED LINE
The VFH is a compact, heated pre-filter offering the ultimate in measurement precision and user-friendliness. This means lasting, complete gas-tightness, careful gas flow and compact, careful construction. The filter chamber has a minimum dead volume and extremely uniform heating with a fast heating-up time, and can accept any IAG filter element. The forward-facing filter fitting seal makes it quick and easy to replace filter elements.
The heat level is controlled by means of 2 heat controllers with settings made on the front panel. The VFH can optionally be supplied with an alarm output for parameter monitoring.
