The PF series, designed for direct interception, filters pollutants up to 1 micron.
The scope of the PF grade filters is very large (Air Power (Air puissance), protection of actuators, tools, pneumatic machines…). They are also used as prefilters to avoid the premature saturation of the highly efficient HF series filters.
The range consists of 18 models covering flows of up to 17.500 cubic meters per hour und a pressure of 7 bars.
All filters come complete and with their filter element(s), a differential saturation indicator and, depending on models, an automatic drain system for condensates.

The Deltech NG PF series prefilters can be used as general usage humid air prefilters of as a protection for high-efficiency downstream deoiling filters.
They can also be used as dessicant particle filter downstream of adsorption compressed air dryers.
The efficiency of these prefilters is guaranteed for a concentration of liquid pollutants (oil/water) of 2.000 ppm at the filter inlet.
All filter bodies are made of aluminium protected against corrosion by a chrome based internal coating.
The new pleated filtration media gives 96% of void volume, thus reducing the pressure loss of 50% compared to traditional filtration media.

Correction factor depending on operating pressure
The dew point is the temperature at which the water vapor begins to condense. The dew point corresponds to a relative humidity of 100%. (This is the saturated water vapor content). The air can not contain more moisture in vapor form, water appears in liquid form (dew) A dew point can be negative (frost point) it is white jelly. The saturated vapor content is not linear with temperature but follows an exponential curve. The warmer the air, the higher its saturating content (e.g. 5 g / m3 at 0 ° C, 82 g / m3 at 50 ° C, 588 g / m3 at 100 ° C) The saturating content is independent of the pressure.
