Abstract
An electrically isolating duct-connecting block for connecting two ducts, the duct-connecting block including a rigid, generally rectangular duct-like structure having upper and lower walls and side walls that match a cross-sectional size of a tie duct, the structure being made of an electrically nonconductive material. The block also includes a plurality of threaded fasteners embedded within the structure. Also disclosed is an electrically isolating nozzle-mounting block for mounting a nozzle to a tie duct, the nozzle-mounting block comprising a rigid flange-like structure having peripheral mounting holes and a central circular passage for conveying air to the nozzle, the structure being made of an electrically nonconductive material. The block also includes a plurality of threaded fasteners partially embedded within the structure. The blocks may be made of ultrahigh molecular weight polyethylene or any electrically and mechanically equivalent material.
