In response to reference 1 and as outlined in reference 2 the Navy Experimental Diving Unit NEDU tested the MAKO 5407 diesel powered high pressure, breathing air compressor from 1 June 90 to 15 June 90. The purpose of this test was to determine if the equipment was suitable for use by the United States Navy USN diving community and if so, added to the Approved for Navy Use ANU Procurement List. The MAKO 5407 met manufacturers specifications for quantity of air produced with a quality which met or exceeded purity standards in reference 3. The design and engineering was determined to be adequate. With the inclusion of the recommendations in section V the MAKO 5407 compressor is considered suitable for USN requirements for compressors of this size and type.
