Buying a regenerative blower for an industrial compressors, blowers, and air treatment application rarely comes down to a single number. In most shops, you are balancing airflow, static pressure, and the electrical service that is already in the building. The two Goorui-USA models here-the GHBH 002 12 1R6 and the GHBH 002 34 1R5-make that trade-off concrete: one model pushes more cubic feet per minute, while the other builds more pressure and vacuum.
Quick Verdict
If your operation is volume-bound, the 2.3 Hp unit is the straightforward pick. If your operation is pressure-bound or vacuum-bound, the 2.8 Hp unit is the better match, and it carries the lower of the two listed prices.

Where Each Product Wins
The 2.3 Hp model wins when you need higher volume and a blower that is easy to pair with a single-phase line. The 2.8 Hp model wins when pressure and vacuum capability are the limiting factors in your process.
Product Notes
2.3 Hp Industrial Blower, 220V 1-Phase (GHBH 002 12 1R6)
The main reason to choose this one is the single-phase 220V input. It saves you the trouble of adding a phase converter or rewiring a space that only has single-phase service, and it still delivers strong airflow for general air treatment duties. The regenerative design is oil-free and maintenance-free, and a six-month warranty is included. It is the volume-oriented member of the pair, which makes it a good fit for continuous air movement and drying. Its clear limitation is pressure: the 2.8 Hp model carries a higher pressure rating, so if your process needs to push against a strong static load, this unit will reach its ceiling sooner.
2.8 Hp Industrial Air Blower, 220V-480V/3-Phase (GHBH 002 34 1R5)
This is the pressure and vacuum specialist. With a 2.8 Hp motor feeding a three-phase design, it reaches a higher pressure rating and a deeper vacuum rating than the single-phase model, which makes it a better candidate for filtration, aeration, and other air treatment work where pressure has to stay steady. It also has a one-year warranty, giving it a longer protection period than the six-month coverage on the 2.3 Hp model. The limitation is on the electrical side: it needs a three-phase supply, so it is not an option for shops that only have single-phase power. If your process depends on sustained pressure rather than maximum air volume, this is the model to plan around.
Final Choice by Use Case
Choose the 2.3 Hp GHBH 002 12 1R6 when your main concern is moving the most air. Choose the 2.8 Hp GHBH 002 34 1R5 when you need higher pressure and vacuum, and your facility can support a three-phase motor.
