The QT Pro 5 HP air compressor combines a horizontal 80-gallon receiver with a two-stage industrial pump for facilities that have the right three-phase power but limited ceiling height. The 460V 3-Phase motor draws less current than lower-voltage versions of the same 5 HP package, making this configuration well suited to buildings with higher-voltage distribution and longer electrical runs. The pump delivers 17.2 CFM at 175 PSI, while a factory-mounted magnetic starter with thermal overload and low-oil shutdown provides built-in protection.
The horizontal receiver keeps the machine to approximately 47" tall while putting the drain, oil sight glass, and belt guard within easier reach. The pump uses cast iron construction with an aluminum head, splash lubrication, and two-stage compression with a high-efficiency finned intercooler between stages. This cooling helps manage operating temperatures and supports the 175 PSI working pressure. An oversized oil reservoir helps control oil temperature during continuous operation, while the slow-speed ODP motor reduces heat and component wear. Automatic condensate draining also removes the need for routine manual tank draining.
This configuration is designed for industrial buildings with 460V three-phase service, particularly facilities where lower current is advantageous for longer cable runs. The horizontal tank makes it a practical choice for low-ceiling plant rooms, bays, and workshops where an upright 80-gallon compressor will not fit. It is also suited to production environments, fabrication shops, blasting applications, and other operations requiring continuous compressed air from multiple tools or workstations.
Two Codes, One Machine
Our records list this unit as 453DS80HCB46 in the title and specifications, and 253DS80HCB46 in the manufacturer copy.
If you are matching an installed machine or ordering parts, ask us to confirm the correct model code before purchasing.
Electrical Requirements
The 460V build uses 5 HP, 460V, 3-phase power. Breaker, conductor and starter sizing depend on the installation, run length, ambient conditions and local code. Have a qualified electrician size the circuit for your facility.
A factory-mounted magnetic starter with thermal overload is included.
Horizontal 80-Gallon Receiver
The horizontal tank keeps the overall height to approximately 47", with a footprint of about 70" × 23". This makes it a good option for low-clearance areas while providing easier access to the drain, sight glass and belt guard.

Install the compressor on a flat, solid and level surface. Site preparation is the buyer's responsibility.
Two-Stage QT-5 Pump
The belt-driven, splash-lubricated QT-5 pump uses a cast-iron design with an aluminum head and high-efficiency finned intercooler. Two-stage compression and intercooling help improve efficiency and control operating temperature at 175 PSI.
-
Output: 17.2 CFM at 175 PSI
-
Oil carryover: <5 PPM
- Two-piece connecting rods
- Oversized oil reservoir
- ODP slow-speed motor
- 100% duty cycle
Automatic Protection
The machine includes:
- Automatic condensate drain
- Low-oil shutdown
- Magnetic starter with thermal overload
- Enclosed belt guard
- Oil sight glass
Automatic draining helps manage receiver condensate, while low-oil shutdown protects the pump from lubrication problems.

Certification, Stated Plainly
The receiver is listed as a coded pressure vessel built to American standards, with relief valves fitted. The electrical components are listed with UL and CSA recognition.
These do not mean the complete assembled machine has a third-party safety listing. If your insurer, inspector, or facility standard requires one, ask us to confirm the applicable documentation before ordering.
Shipping & Receiving
Ships palletized freight throughout the lower 48 states. Shipping is calculated at checkout based on your delivery address.
Plan unloading before ordering. Have a loading dock, forklift, or pallet jack ready on firm, level ground. If unavailable, terminal pickup may be an option. Residential delivery carries an additional fee.
Inspect before signing. Photograph the pallet/crate and record any damage on the bill of lading with the driver present. Damage discovered after a clean signature may be difficult to claim.
Warranty
The machine includes a 1-Year factory warranty and may qualify for Quincy's 3-Year “No Bull” warranty, subject to manufacturer requirements. Review the warranty terms and confirm the conditions for this model before relying on the extended coverage.
