SPECIFICATIONS TYPE Self contained, fully enclosed, diesel engine driven, heavy duty portable air compressor mounted on a four wheel trailer with a minimum rated capacity of 1070 cfm, free air delivery, at operating pressure of 350 psi and in accordance with ISO 1217. The rated pressure shall be measured after oil separation. GENERAL The equipment shall be a standard product of the manufacturer. The compressor airend shall be completely manufactured and assembled by the manufacturer of the compressor unit. The compressor unit shall meet the EPA noise level regulations of 76 dba at 7 metres. The manufacturer shall have local parts and service facilities capable of complete machine overhaul, ensuring minimum down time. Additionally, the compressor manufacturer shall have a flexible airend repair program; i.e., parts and training may be obtained to make repairs, or the airend may be exchanged for a new or remanufactured unit. The equipment shall adhere to the specifications contained herein. ENGINE The diesel engine shall be a turbocharged and aftercooled, industrial, water cooled six cylinder, with a rating of no less than 465 SAE brake horsepower, at 1800 rpm. The engine shall have a 24 Volt electrical system and each battery shall have a minimum rating of 1400 cold cranking amps in accordance with SAE J537 specifications for 30-second test. A dedicated heavy duty, two stages, dry type air cleaner, with replaceable element and an automatic filter maintenance indicator, shall be used to filter intake air. The fuel system shall have a capacity of at least 680 litres and a replaceable fuel filter. The compressor airend shall be two-stage oil flooded rotary screw type with asymmetrical rotor profiles incorporating tapered roller thrust bearings. The airend shall be driven through a flexible coupling to isolate engine and compressor vibrations. The regulation system shall permit low load engine starting and warm up. It will also provide stepless engine speed control. A dedicated heavy duty, two-stage, dry type air cleaner, with replaceable element and automatic filter maintenance indicator, shall be used to filter intake air. COOLING SYSTEM The engine and compressor oil heat exchangers shall be arranged in a side-by-side configuration for easy cleaning. The cooling air fan shall draw air into the unit, across the airend and engine and then expel it through the coolers. This routing shall be used to maintain internal package temperatures of no more than 20 F above that of the ambient. There shall be a low coolant indicator on the control panel. OIL SYSTEM The compressor oil system shall incorporate a vertical separator tank, a temperature bypass valve, oil cooler, and a 25-micron spin-on oil filter. The separator tank shall meet ASME Section VIII Code requirements, have a minimum capacity of 350 litres, and include an oil level sight gauge and over-fill protection.
TRAILER The trailer shall be a four-wheel wagon type design using heavy-duty leaf spring running gear with 15- inch bias ply tyres. The trailer shall be of welded steel construction and include a replaceable, bolt-on drawbar and rear bumper. The engine and airend shall be rubber mounted directly to the trailer to minimise vibration. An internal, single point, lifting bail capable of lifting the complete unit shall also be included. The lifting bail shall be accessible from the inside so as to eliminate the need to climb on the roof of the compressor. A step shall be supplied to allow safe and easy access to the radiator fill cap. ENCLOSURE Sheet metal housing shall fully enclose the compressor unit providing protection as well as noise attenuation. Access for routine maintenance shall be provided through the large doors located on all sides of the compressor. These doors shall be lockable and equipped with no-rust aluminium hinges. INSTRUMENTS & CONTROLS The instruments and controls shall be clearly labelled and located on the front of the unit, accessible without opening the main side doors, and protected with a separate lockable door. The instrument panel shall be hinged for easy access and it shall include the following gauges: hourmeter, tachometer, discharge air pressure, discharge air temperature, engine water temperature, voltmeter, fuel level and engine oil pressure. The instrument panel shall also include indicator lights for low engine coolant, alternator malfunction, air cleaner service indicators and all safety shutdowns. SAFETY FEATURES The compressor unit shall incorporate the following features to ensure operator safety and to protect the equipment: fan guards meeting OSHA recommendations, operating and maintenance manuals, operating and safety decals in accordance with ANSI Z535.4-1996, automatic and manual blowdown valves, an ASME approved pressure relief valve on the oil separator tank, safety shutdown devices in case of high compressor discharge temperature, low engine oil pressure, high engine coolant temperature and low fuel level. The engine starting motor shall be protected from excessive wear by the presence of a starter protection system. This system will not allow the engine to be cranked while there is more than 20 psi in the separator tank. WARRANTY The air compressor package shall be warranted to be free of defects in material and workmanship for a period of one year or 2000 operating hours, whichever occurs first. The airend itself shall be warranted for two years or 4000 hours, whichever occurs first. Their respective manufacturers shall warrant the battery, tyres and engine.
