The purpose of this amendment is to post a second set of Questions and Answers pertaining to this requirement. February 15, 2008 Second set of Questions and Answers to Solicitation number M00146-08-T-N044 Q1. With respect to providing a compact, portable vacuum that can fit well within the 30-inch width constraint outlined in your last response, can the Government accept our standard 23-gallo drawer mounted drum (drum slides out from beneath the vacuum head), rather than limiting the volume to the 16-gallon spec? In either case, the limit of 1# of aluminum dust accumulation will result in drum removal prior to its filling. Answer: No. As stated in paragraph 2.ee. of the Essential Characteristics the vacuum dust storage bin capacity shall be no less than 3 gallons and no greater than 16 gallons. Q2: We offer an optional drum level detection system that can be indicate either drum weight or drum fill level. Does the Government have any interest in an integrated drum level detection system? Answer: No. Q3: We offer our units will mutliple ports to support the simultaneous operation of multiple hoses of various lengths. Our standard flow rates are 70% greater than the minimum flow rates specified at the various vacuum levels to support this feature. And our standard filter area is 200% times the minimum 80SF specified. As a consequence, maximum hose lengths exceed those set forth in the manifold descriptors (e.g., Section 2.3 of the specification) by very wide margins (at least 200 ft.). Our question is this: Can the government accept deployment of a portable HEPA vacuum system capable of simultaneous supporting up to 6 hoses of various lengths up to 200 ft. as an alternative to the hard-tubed, segmented vacuum manifold and hose combinations described in the specification? Answer: No. The Fleet Readiness Center East at the Marine Corps Air Station, Cherry Point, NC has a requirement for explosion proof HEPA vacuums with accessories.
