CITY OF WINOOSKI | DEPARTMENT OF PUBLIC WORKS
1. INVITATION TO BID
The City of Winooski Department of Public Works is requesting sealed bids for the purchase and delivery of one
(1) new industrial-duty, two-stage reciprocating air compressor for use at the City's Public Works maintenance
facility.
Reference unit: Atlas Copco CR Industrial Series, Model CR10-TS-120GV-IS, Part Number 2020040045, 10 HP,
230V, 3 Phase, 120-gallon vertical receiver.
The City will consider the reference unit or an approved equivalent from an established industrial compressor
manufacturer, provided the proposed unit meets or exceeds the minimum specifications in this RFB. The
reference manufacturer and model establish the general level of quality, configuration, capacity, and performance
required and are not intended to unnecessarily restrict competition.
2. INTENDED USE
The compressor will serve as the primary shop air compressor for the City of Winooski Department of Public
Works maintenance facility. Typical applications include:
* Maintenance and repair of municipal trucks and heavy equipment
* Pneumatic impact tools and other air-operated shop tools
* Tire service and inflation
* Equipment cleaning and blow-off
* General fleet and equipment maintenance
* Other normal municipal Public Works garage operations
The equipment supplied shall be designed and rated for industrial/commercial shop service.
3. MINIMUM TECHNICAL SPECIFICATIONS
Type Industrial-duty, two-stage reciprocating/piston
compressor
Motor 10 HP minimum
Electrical 230 VAC, 3-phase, 60 Hz. A dual-voltage 208/230V
three-phase motor is acceptable if fully compatible
with the City's 230V three-phase service.
Air Delivery Minimum 35 ACFM/CFM at 175 PSI. Published
manufacturer documentation identifying air delivery at
175 PSI shall be included. Ratings stated only at
lower pressures will not establish equivalency unless
the manufacturer also documents at least 35 CFM at
175 PSI.
Maximum Working Pressure 175 PSI minimum
Compressor Stages Two-stage
Pump Industrial-duty, oil-lubricated, cast-iron or equivalent
heavy-duty construction designed for
commercial/industrial service.
4. AIR RECEIVER
* 120-gallon minimum receiver
* Vertical receiver configuration
* ASME-rated/certified receiver tank
City of Winooski - RFB: 10 HP Two-Stage Industrial Air Compressor | Page 3 of 10

CITY OF WINOOSKI | DEPARTMENT OF PUBLIC WORKS
* Safety relief valve
* Tank pressure gauge
* Automatic/electric drain system
* Minimum 1-inch compressor air outlet preferred
The City prefers a vertical configuration because of available shop floor space. Any proposed receiver larger than
120 gallons must fit the City's available installation area and shall be clearly identified in the bid.
5. REQUIRED EQUIPMENT AND FEATURES
* Magnetic motor starter
* Automatic/electric tank condensate drain
* Air-cooled aftercooler
* Low-oil-level shutdown/protection system
* Head unloaders or equivalent reduced-load starting system
* Fully enclosed OSHA-compliant belt/flywheel guard

* Intake filter/silencer
* Oil-level sight glass or other readily accessible oil-level indication
* Appropriate motor overload protection
* All factory-required controls necessary for normal operation
All required accessories shall be factory installed whenever available. The compressor shall be supplied as a
complete operational package and shall not require the City to purchase additional components necessary for
normal operation, other than site-specific electrical connection, air piping, mounting hardware, or installation
materials specifically identified in the bid.
6. CONSTRUCTION AND DUTY
The compressor shall be designed for heavy commercial or industrial shop use. The City may consider the
following characteristics when evaluating responsibility, serviceability, and total cost of ownership:
* Low compressor pump operating speed
* Heavy-duty cast-iron pump construction
* Replaceable/rebuildable compressor components
* Readily available replacement parts
* Strong regional parts and service support
* Proven commercial/industrial service history
Consumer-grade or light-duty compressors will not be considered acceptable.
7. REFERENCE UNIT

230V, 3-phase; two-stage reciprocating compressor; 120-gallon vertical receiver; approximately 35-35.9 ACFM;
175 PSI class; 1-inch air outlet; and industrial package configuration. Equivalent equipment is encouraged.

documentation for the City to determine equivalency. Products from established industrial compressor
manufacturers, including Atlas Copco, Ingersoll Rand, Quincy, Castair, Champion, EMAX, or other established
manufacturers, will be considered.
Brand name alone does not establish equivalency. Any exception or deviation shall be clearly identified with the
bid. Failure to identify an exception may be interpreted as confirmation that the proposed equipment fully
complies with the specifications.
