Quincy Air Compressor 30 HP 132 Gallon Rotary Screw 3 Phase

The Quincy QGS 30 HP rotary screw compressor is built for continuous-duty shops where maintenance intervals and operating costs matter as much as airflow. Part number 4152026533 uses an oil-injected twin-screw airend with a 100% duty cycle and premium synthetic fluid rated for up to 8,000 hours, helping reduce the frequency of fluid changes while limiting oil carryover into the air system. The package includes a 132-gallon horizontal receiver, aftercooler, full sound enclosure, and Infologic2 control on one skid. Note: it measures 74" × 30.7" × 72.2", weighs 1,237 lbs, and requires 208–230/460V three-phase power.

The 8,000-hour fluid interval is especially relevant for a compressor that runs throughout the workday. Constant fluid monitoring, a spin-on fluid filter, oil sight glass, and low-oil shutdown on both the engine and pump help protect the airend and simplify routine maintenance. The oil-injected twin-screw design provides steady compressed-air delivery without the pulsation of a reciprocating pump, while the 100% duty rating allows the machine to operate continuously. A full sound enclosure helps reduce operating noise, and the TEFC motor provides IP55 wash-down protection. The Infologic2 Basic controller also supports programmable auto-restart, remote start/stop, and networking with up to six compatible compressors.

This compressor is suited to busy automotive shops, fabrication facilities, production environments, and other operations with sustained air demand. Its compact, long-and-narrow package works well along a wall, provided there is enough clearance to open the service panels and maintain airflow. The 1" receiver outlet provides the connection point for properly sized shop piping. An electronic drain valve is not included, and electrical feed, disconnect, plumbing, and commissioning are the customer's responsibility. Have a certified electrician verify the required electrical installation before delivery.

Will It Fit? Siting and Power

Footprint. 74" long, 30.7" wide, and 72.2" tall, with a shipping weight of 1,237 lbs. The horizontal receiver gives the package a long, narrow footprint that generally suits a wall run better than a floor island. Leave enough clearance to open the hinged doors and remove the detachable panels — the serviceability this machine is designed for depends on having access around the enclosure.

Electrical. The motor is listed as 208–230/460V, 3-Phase. Quincy does not publish an amp draw or recommended breaker size for this configuration and states that a qualified electrician should be consulted. We are not going to substitute an estimated number for a manufacturer specification. Your electrician should size the feeder and overcurrent protection from the nameplate on the delivered machine. Arrange that evaluation before delivery, not after the compressor is sitting on the floor.

Plumbing and drainage. The receiver outlet is 1". An electronic drain valve is listed as not included, so condensate from the 132-gallon receiver must be managed manually unless a suitable drain system is added. Assign this task to someone and put it on a regular schedule; condensate management is part of owning a compressed-air system, not an occasional cleanup job.

Confirming that the room, floor, electrical supply, ventilation, and drainage are suitable for a compressor designed for continuous operation is the customer's responsibility. It is also considerably easier to resolve those requirements before the crate arrives.

Why an 8,000-Hour Fluid Interval Changes the Numbers

Rotary screw compressors are purchased based on capacity but owned through their maintenance and operating costs. The fluid service interval sets the pace for a significant portion of that maintenance.

A synthetic fluid rated for up to 8,000 hours can substantially extend the interval between fluid changes compared with shorter-interval systems, particularly in applications with long operating hours. The actual service schedule should still follow the manufacturer's maintenance requirements and operating conditions.

Low oil carryover matters for more than fluid consumption. Oil that passes downstream can contaminate compressed-air piping, filters, tools, and finished work. Keeping separation and filtration performing properly therefore protects both the compressor and the equipment using its air.

The specified fluid filter, oil sight glass, and low-oil shutdown protection provide additional monitoring and protection, reducing reliance on operators simply remembering to check the system.

Oil-Injected Twin Screw: What the Enclosure Adds

An oil-injected twin-screw airend compresses air continuously between two meshing rotors rather than through the repeated piston strokes of a reciprocating compressor. In practical terms, that means smoother operation, lower vibration, and a more consistent compressed-air supply without the pulsation associated with piston compression.

The 100% duty-cycle rating is particularly important for applications with sustained demand. Rather than requiring regular rest periods, the compressor is designed for continuous operation when properly installed and maintained.

The full sound enclosure complements that design by helping contain operating noise. The TEFC electric motor is rated IP55, providing protection against dust and water jets, which is useful in demanding shop environments. A Wye-Delta reduced-voltage starter also helps reduce electrical inrush during startup.

The Infologic2 Basic microprocessor controller provides programmable auto-restart and remote start/stop functions and can network up to six compressors. The display provides operating indications including auto-run, general alarm, and power-on status, along with pressure and temperature information.

Perfect For

• Shops watching operating costs. The 8,000-hour fluid rating can help extend maintenance intervals and simplify long-term planning.
• Single-delivery installations. The compressor and 132-gallon receiver are packaged together on one skid.
• Demanding shop environments. The IP55 TEFC motor provides added protection against dust and water exposure.
• All-shift air demand. The 100% duty-cycle design is suited to applications where compressed air is required continuously rather than intermittently.

What's in the Box

Quincy lists the package as the QGS rotary screw compressor with Infologic2 Basic controller and display panel, TEFC electric motor with IP55 protection, and 132-gallon horizontal receiver.

The listed equipment also includes an aftercooler, oil sight glass, pressure gauge, air filter, and low-oil shutdown protection for the engine and pump. An electronic drain valve is listed as not included.

Specifications

Certification, Stated Honestly

The specification sheet records an ASME certification for this unit, which applies to the 132-gallon receiver — a pressure vessel that is subject to specific construction and testing requirements.

What our product data does not document is an independent electrical or equipment safety listing covering the packaged compressor as a whole, and we are not going to imply that one exists.

If your jurisdiction, insurer, or internal engineering standards require a specific third-party listing for permanently installed equipment, confirm that requirement before purchasing and before installation. Ask us and we can obtain the available manufacturer documentation in advance so you can verify the unit against your requirements.

Shipping and Delivery

Freight only to the lower 48 states, with shipping quoted live at checkout based on the delivery address you enter.

At 1,237 lbs on a long skid, the shipment requires an appropriate unloading method. Plan for a loading dock or forklift at the delivery location, or arrange pickup from the carrier's terminal if that better suits your facility.

Residential delivery may carry an additional residential fee, which will be shown at checkout when applicable.

Inspect the shipment before signing for delivery. If you find visible damage, document it with photographs and have the damage noted on the bill of lading before signing. Once the shipment has been accepted without notation, resolving a freight-damage claim can become significantly more difficult.

Warranty

Published standard warranty coverage is 1 year for consumer use and 1 year for commercial use. An extended 3-year factory warranty is available, and the True Blue 5-year warranty applies when the compressor is commissioned through a Quincy-authorized start-up, subject to the applicable warranty terms and conditions.

That authorized start-up requirement matters. If the 5-year coverage is important to you, arrange the required commissioning before the compressor is put into service, rather than assuming the coverage can be added later.

For any potential warranty issue, contact us before disassembling the compressor, airend, or motor. Unauthorized disassembly can complicate the warranty assessment and make it more difficult to establish the cause of a failure.
