Dryer protects moisture-sensitive
pneumatics
A novel high performance compressed air/gas dryer system allows easy desiccant change, long life and low pressure drop in point of use and OEM applications.
Parker Filtration has introduced a novel high performance compressed air/gas dryer system - the Finite FDD Series - designed for easy desiccant change, long life and low pressure drop in point of use and OEM applications The FDD Series dryer system provides clean, dry air for all types of moisture-sensitive pneumatic application needs, eg protection of instrumentation, protecting air tools against gumming and oxidation, preventing fisheye defects in automotive body paint systems, valve actuation and instrument air

Trubind 700 absorbent cartridges
Parker Filtration has introduced Trubind 700 - which removes free, emulsified and dissolved oils in many process fluids
Available in a eleven models with 0.25 to 1in BSPP ports, the FDD Series dryers remove water vapour and aerosols at point of use applications with intermittent flows up to 100m3/h.
The dryer provides pressure dewpoints to -40C and does not require steady flow for constant dewpoint suppression.
As wet compressed air flows through the inlet port of the FDD dryer and down through the desiccant bed, the desiccant beads adsorb the water vapour and aerosols.
The highly effective silica gel beads reduce the pressure dewpoint to -40C.
Condensation cannot occur in the downstream air lines unless the compressed air is exposed to a lower temperature than the dewpoint.
After the moisture has been removed, the dry air passes through a sintered bronze element, up the centre tube and out through the outlet port.
A built-in sightglass allows easy monitoring of the blue silica gel desiccant as it becomes saturated and turns pink indicating the need for replacement or regeneration.
The desiccant can be regenerated by heating in a drying oven or in a microwave oven.
Additional features of the silica gel desiccant include high adsorption capacity, long service life resulting from low abrasion as a result of the high mechanical strength of the beads, ideal packing density in bowl due to bead shape, uniform colour change and excellent regeneration characteristics.
