Every compressed-air project eventually comes to the same fork: do you spend on the machine that makes the air, or the tank that holds it? For anyone planning an air-treatment setup, the choice often comes down to a rotary screw compressor and an ASME receiver tank. They are not substitutes; they are the supply side and the storage side of the same system. Getting the order wrong means either buying air capacity you cannot store, or buying storage volume you cannot fill.
Quick verdict
If you need the module that actually creates compressed air, start with the rotary screw compressor. If you already have a screw compressor on the larger end and need reserve volume, start with the ASME receiver tank. The listed prices sit $1,100 apart: the compressor is $3,099 and the tank is $1,999.

Where each product wins
The compressor wins when compressed air has to be generated. It is the only product here with a stated airflow rating, and it is built as an industrial-grade heavy-duty unit. That makes it the right side of the comparison for shops that add tools or machines faster than their existing air source can keep up.
The receiver tank wins when your problem is storage. It delivers bulk reserve volume and carries a higher maximum pressure rating than the compressor. If your air is being made but the system short-cycles from pressure swings, this is the side to favor.
Product notes
3 Phase 10HP Rotary Screw Air Compressor 34 CFM 125 PSI 230V Industrial Grade
This is the air generator in the pair. It is a fixed-speed 10HP rotary screw unit running on 230V 3-phase 60Hz power, with star-delta starting, 34 CFM of displacement, and 125 PSI maximum pressure. It includes a user-friendly controller and an oil-air separator, which makes it a more complete compressor package for a shop that needs industrial airflow. This is the right pick when your bottleneck is producing air on demand rather than storing it. The main trade-off is the fixed-speed design: output doesn't adjust to variable demand, so it suits steady 3-phase operations rather than start-and-stop schedules.
Industrial Air Compressor Receiver Tank Vertical Horizontal ASME 270 Gallon
This is the storage side of the system. It is a receiver built from carbon steel, rated to 160 PSI, and designed in line with ASME Section Code for compressed air storage. It offers 1-inch, 2-inch, and 3-inch NPT connections, so there are multiple hookup options for an existing compressed-air layout. The intended companion is a screw compressor rated 22kW or more, meaning it is meant to sit downstream of a substantial air source. If your compressor already produces enough air but the system needs pressure buffering, this tank is the one to pair with it. The limitation is that it does not create air; it only stores air made upstream.
Final choice by use case
- Choose the rotary screw compressor when the gap in your system is generation: you need an industrial-grade air source that can keep pace with the tools you already run.
- Choose the ASME receiver tank when the gap is storage: you already have a screw compressor rated 22kW or more, and you need reserve volume plus multiple NPT hookup options to smooth out pressure swings.
- Building from scratch? The compressor is the logical first major purchase, because nothing downstream works without air being made.
