PFE2 Filter unit

Design The PFE2 filter unit consists of the FE2 filter unit with a regulat-ed heating sleeve, installed in a special-steel protective case. It is used to filter dust-containing gases and is a component of the modular gas sampling probe system. When used for gases with high dust content, the PFE2 can optionally be fitted with valves for automatic cleaning of the filter element in the FE2 filter unit.

Annular heating element

Use The annular heating element is used for heating the FE2 filter unit, which is a component of the modular gas sampling probe system (see page 3). Heating is necessary if condensation is likely from moist gases and there is consequently risk of the filter becoming clogged and corroded. Data Power supply

120 V AC or 230 V AC, 50 to 60 Hz Heater output

200 W, 100 W or 50 W – depending on setting (see below) The heating resistors are factory-set for heat output of 100 W

Temperature of heater (unregulated)

Approx. 120 °C to 180 ° C (measured at ambient temperature of 20 °C, still air)

Ambient temperature

0 to 55 °C (still air) Degree of protection of housing

IP50 Materials

Housing: aluminum alloy, heating surface: brass Weight

Approx. 1.7 kg Electrical connections

Terminals via M20 cable gland. The electrical supply conductor must be heat resistant ( 200 °C).

Installation Two half shells are placed round the FE2 filter unit to be heated and closed with a wing screw. Option Regulated heating with 1 x Pt 100 Heating circuit

Ceramic filter

Use For filtering dust from gases in the gas conditioning systems of analyzer systems when the gas sampling probe does not have a filter. The ceramic filter is positioned upstream the other devices in the sample gas conditioning chain. The ceramic filter can be heated with the annular heating element if condensation from the sample gas is likely. Technical data Flow rate (air)
