Waveguide Air Pressure Unit Prevents arcing of radio frequency energy Dry air is essential to prevent arcing of radio frequency energy, which can damage the waveguide and radar power amplifier. The Waveguide Air Pressure Unit from Parker domnick hunter is designed to provide a continuous supply of clean, dry compressed air that prevents arcing and improves power handling duties on ground based waveguide radar systems. Air is filtered and dried to remove water vapour and potentially damaging particles down to 1 micron in size. Dual compressors provide a fail-safe security function; in the event of a primary compressor failure, a secondary compressor maintains pressure to ensure that waveguide system performance is maintained. The unit interfaces with radar Built In Test Equipment (BITE) to indicate high temperature and low pressure and also has local “normal operation” alarm neons on the facia panel.
