DECEMBER 30 2013 REVISIONS -- THE Compressor business has expanded greatly. CNG Compressors and AIR compressors options have been added to meet market interest. These include old standards -- KIDDE, BRISTOL, BAUER, MAKO, and INGERSOL-RAND 15T4. Available models include , 4.2 CFM KIDDE 4500PSI, 5.5 CFM and 8.5 CFM BAUER 5000PSI units, 5.2 CFM BRISTOL 4S7 5000PSI units, MAKO REBUILT SYSTEMS, 5.2 CFM BRISTOL 6000PSI compressors (over 100 available) and parts for breathing air, paintball and high pressure air guns. Recently I purchased 15 Kidde 4.2 CFM units, many new in the box (unused) of the current manufactured series with all stainless intercoolers. CNG COMPRESSORS -- Work has been completed with a certified engineer in Nebraska (Grassroots Energy) to install and certify a MAKO unit for CNG Service. We received Nebrask State Fire Marshal approval of this installation. COPY OF THE CERTIFICATION IS AVAILABLE UPON REQUEST. The 5 CFM BRISTOL now have the same capability. We have just completed the installation of a IR 15T4 (10.5 DGE/HR) CNG unit and have more available. Since 1968, Shelden Sporting Goods Inc. has been building and servicing compressors for Fire Departments, SCUBA shops, Airgun and Paintball applications. We specialize in repair and service for Military high pressure compressors. In addition to owning a dive shop, I was an American Bristol dealer for over 25 years. I understand the business and individual diver's needs. We design AIR and CNG systems to meet volume and cost objectives. We assist individuals who modify military surplus compressors to achieve a safe and dependable system. Unit/prices are available and current.

a grassroots.txt - MAKO CNG conversion. My engineering associate (Grassroots Energy) Kevin Kenny, and I collaborated on the conversion of a MAKO 8 CFM commercial compressor for a Nebraska COOP and received the approval of the Nebraska State Fire Marshall and the system meets NFPA72 requirements
We installed explosion proof components (motors, switches, etc.) and moved all the relief valves to the tower above the compressor. Drain valves are located to the side of the unit (6 ft away). We have since found ported relief valves (approved) and will use them on subsequent conversions. Modifications can be installed on other commercial compressors as well. EXAMPLE ONLY - NOT FOR SALE
