Required Salient Characteristics

The contractor shall meet and provide all salient physical, functional, and performance requirements in this solicitation as brand name “or equal.”

1) (1 QTY) EagleAir BlackhawkCFS Breathing Air Compressor System (or equal)

2) (1 QTY) Integral 50-ft. 6000 psig hose reel (or equal)

Breathing Air Compressor System- 14.0 cfm, 6000 psig, 10-hp three-phase electric motor drive, complete with two SCBA certified containment fill station and standard accessories as per the attached specifications, drawings and technical data. Integral 50-

ft. 6000 psig hose reel, mounted on compressor. The air compressor system shall be a turnkey, packaged appliance designed to deliver high pressure breathing air in compliance with the most current NFPA and CGA air quality standards for the refilling of SCBA and SCUBA cylinders. The system shall include the high pressure air compressor, electric motor, air purifier, fill station and all operating and cylinder fill controls as specified below. The system must also be designed to incorporate an integral air storage system as specified below. All components shall be completely assembled and tested by the manufacturer as a system and incorporated within a single appliance requiring only electrical power supply to operate. The system shall be designed with all cylinder refilling, operator controls and performance indicators located on panels at the front of the appliance allowing "at sight" operator monitoring. The appliance shall comply with the currently applicable OSHA specifications as well as state and local electrical codes. All high pressure air plumbing shall be rated for 6000 psig working pressure and utilize seamless stainless steel tubing. All high pressure air tube connections shall use compression type design fittings.

Electrical Control System (or equal)

The electrical control system shall include motor control components with UL, NEMA or IEC approval and 12vdc control circuit housed within a UL® listed, NEMA enclosure.

The breathing air system manufacturer shall be a NRTL (Nationally Recognized Testing Laboratory) Licensed Panel Shop as per UL® 508A standard.

General Arrangement The air compressor system shall be a turnkey, packaged appliance designed to deliver high pressure breathing air in compliance with the most current NFPA and CGA air quality standards for the refilling of SCBA and SCUBA cylinders. The system shall include the high pressure air compressor, electric motor, air purifier, fill station and all operating and cylinder fill controls as specified below. The system must also be designed to incorporate an integral air storage system as specified below. All components shall be completely assembled and tested by the manufacturer as a system and incorporated within a single appliance requiring only electrical power supply to operate. The system shall be designed with all cylinder refilling, operator controls and performance indicators located on panels at the front of the appliance allowing “at sight” operator monitoring. The appliance shall comply with the currently applicable OSHA specifications as well as state and local electrical codes.

Compressor (or equal)

The ambient air intake and compression shall be through an air-cooled, reciprocating, four-stage compressor designed for continuous duty at 6000 psig working pressure. The compressor shall have a minimum charging rate of 14.0 cfm. The air compressor design shall include a heavy-duty crankcase supporting the crankshaft with ball bearings on each end. Lubrication shall be accomplished by controlled splash of oil from the crankcase sump aided by pressure induced migration from the totally sealed crankcase.

The crankcase shall be piped back to the inlet cylinder to maintain proper crankcase pressure and eliminate any discharge of oil contaminated air to the atmosphere. The cylinder arrangement shall be a balanced “V” configuration featuring double-acting, ringed pistons assuring maximum balance and air volume delivery efficiency while operating at a maximum compressor speed of 1700 RPM.

Electric Motor (or equal)

The compressor shall be v-belt driven by a NEMA design, 10-hp, open drip proof electric motor wired for the electrical conditions as shown below: 60 Hertz Current

3 Phase, 208/230 volts 3 Phase, 460 volts

Electrical Control System (or equal)

The breathing air compressor shall include all the necessary controls to assure safe, efficient operation and monitor performance. The control system shall be of an anti-flutter circuit design and include a latched fault protection circuit to prevent automatic restarting after an abnormal fault has occurred.

Instrumentation (or equal)

The control system must include all monitoring devices as indicated below.

These shall be mounted on a control panel located at the front of the compressor with all indicators and gauges grouped logically and each group positioned within a graphic flow control schematic and identified with integral text. The panel background color shall be matte black shade with a textured finish to eliminate glare. Panel component and indicator groups shall be offset by colored lines to enhance operational visibility and safety.

Air Purification System (or equal)

The high pressure air purification system shall be a multi-chamber arrangement that utilizes disposable cartridges manufactured to provide breathing air that meets or exceeds NFPA and CGA Grade “E” specifications and all other equivalent and recognized standards in use worldwide.

High Pressure Air Storage (or equal)

The breathing air storage system shall be integral to the appliance and include all the cylinders, plumbing and hardware installed in accordance with all current ASME codes, as specified below:

Four (4) ASME 6000 PSI cylinders each with a capacity of 491 cubic feet of air at 6000 psig. The piping of air storage shall be arranged for cascade filling

All high pressure regulators must be designed so that they cannot be accidentally reset in accordance with NFPA 1901 standards. The regulator knob shall be of the “push-to-reset” design that spins freely if accidentally moved.

All air flow components and indicators shall be mounted on a control panel located at the front of the unit grouped logically with each group positioned within a graphic flow control schematic and identified with integral text. The panel background color shall be matte black shade with a textured finish to eliminate glare. Panel component and indicator groups shall be offset by colored lines to enhance operational visibility and safety
