For extraction of this water a condense water drain has to be installed at the lowest point of the scroll. The drain will be provided with a thread for connecting it to a piping. At order please indicate the required casing position. Connecting thread / hole A ADH / RDH = female thread R 1/8" A AT = drain hole A RZR 0200/-1000 = male thread R 1/2" A RZR 1120/-1600 = male thread R 1" Dimensions For the purposes of maintenance and cleaning there is an opening, which can be securely closed by means of an access door, in the fan casing. As it can only be opened with a tool, the access door complies with safety and accident prevention regulations. Additional securing with locking bars can be supplied on request. The site and orientation of the inspection opening depends on the casing position. The position should be specified when ordering according to the following diagram: e.g. Access door, Pos. 2.

Fittings / Accessories Corrosion Protection Systems Continuously welded blades Continuously welded scroll Belt Driven Centrifugal Fans / Fittings and Accessories Nicotra Gebhardt fans are treated with high quality corrosion protection as standard. Under extreme operating conditions, however, additional corrosion protection is advisable. ADH / AT / RDH Extended corrosion protection for series ADH, AT and RDH only available on request. RZR Depending on the use to which the fan is to be put and the degree of exposure to corrosion, we offer various anti-corrosion protection measures.

The continuous welding has no influence on the material resistance or on the max. tip speed. The casing can be continuously welded in order to increase the corrosion resistance when conveying a humid or slightly aggressive medium. By continuous welding the casing is provided with additional impermeability. A GEH 01 - Casing inside continuously welded A GEH 02 - Casing inside and outside continuously welded 203
