PURCHASE DESCRIPTION

Blast Booth 44 Screening System - BLDG 350

1. GENERAL REQUIREMENTS

1.1. SCOPE: This specification shall apply to adding media screening equipment to the media recycle system for blast booth #44 in building 350. The purpose for this screening system is to allow the media changeover from garnet to stainless steel grit.

The screening system will aid in recycling all the usable stainless steel grit since it is a more expensive blast media. The screen system will sieve all used media and send back into the blast booth any media that is larger than a 30 screen size and smaller than a 100 screen size particle. The blast booth will be located at building 350 at Letterkenny Army Depot (LEAD), Chambersburg, PA. The specification calls for a turnkey operation and the successful contractor shall install the new system, any ductwork required and associated components herein in their entirety, including all necessary electrical, plumbing for compressed air, ventilation, fire alarm system tie in, and ductwork modifications required for system operation. The contractor shall furnish all materials, equipment, and labor needed to meet all requirements described in this solicitation and shall provide a complete and usable system. The contractor shall also perform testing to indicate full operational compliance with this contract and shall also provide system training for necessary personnel at 350.

1.2. GENERAL INFORMATION
