Product description

Notes
After saturation, the adsorber filter can be opened and refilled.
The spare parts HK FI AD ETS and the desiccant HK FI AD SK can be found under accessories.
Other variants with housing made of aluminum and stainless steel and for aggressive media are available on request.
Design bases are medium, air flow rate or clunk pick-up volume.
Description
The adsorber filters in the HK FI AD MV NAF series are aeration dryers with a reusable cartridge and a valve base.
They are suitable for indoor, outdoor and offshore use on hydraulic units, gearboxes, storage tanks and mobile machines.
The plastic housing is filled with HANSA-FLEX Xdry. The desiccant mixture ensures effective drying of the supply air.
A 3 µm filter additionally cleans the air drawn in.
A layer of activated carbon adsorbs the oil mist that escapes with the air.
If the adsorber filter is saturated, both the desiccant and, if necessary, all other internal components can be replaced inexpensively.
The sturdy frost-proof valve section protects the adsorber from unnecessary loading, enables use under extreme, dusty environmental conditions and ensures minimal pressure build-up even at high air flows.
Further information
In the adsorber filter, the water molecules contained in the air are bound in the pores of the adsorbent (HANSA-FLEX Xdry). Saturation (loading) and the need to replace the filter cartridge is indicated by a colour change from orange to green.
HANSA-FLEX Xdry consists of silicon oxide and zeolite and is classified as a synthetic, polar and hydrophilic drying agent. Due to its high porosity, it has a large inner surface area. This enables a very high water absorption capacity.
HANSA-FLEX Xdry with a colour indicator is used in the adsorber filters. Colour changes indicate the water content and thus the progress of the loading of the desiccant.
The mixture of silicon oxide and zeolite is not classified as a hazardous substance according to European Union legislation (Regulation EC number 1272/2008). It is not subject to labelling according to the EC Directive (67/548/EEC or 1999/45/EC). It is not classified as a substance hazardous to health or the environment.
Ordering information
For mounting on the tank, the KH FI AD FS FILL filling flange is required.
