The Buying Choice: Which Goorui Blower Matches Your CFM Need?
When you need a regenerative blower for pressure or vacuum duty, the first question is usually not brand or enclosure-it's how much air you actually need to move. Goorui-USA offers two three-phase industrial blowers that look similar on the outside but split on exactly that question. Both share the same port size and voltage/phase rating. From there, airflow, power, and listed price separate them.
Which one should go into your setup? The answer comes down to your required CFM and whether the extra capacity of the larger model is worth the jump in list price.
Quick Verdict
If your pressure or vacuum application runs comfortably at the lower-flow model's output, the Goorui GHBH 1D7 34 1R5 is the straightforward pick. If you need more air volume and extra pressure headroom, the Goorui GHBH 002 34 1R7 is the one to buy.
Side-by-Side Comparison
| Spec | Goorui GHBH 1D7 34 1R5 | Goorui GHBH 002 34 1R7 |
|---|---|---|
| Listed price with price bar | USD 699.00 · | USD 989.00 · |
| Rated power | 2 Hp | 2.8 Hp |
| Maximum flow rate | 150 CFM | 221 CFM |
| Pressure | 56" H2O | 60" H2O |
| Voltage / phase | 220-480V / 3Ph | 220-480V / 3Ph |
| Inlet / outlet diameter | 2 in / 2 in | 2 in / 2 in |
| MPN | GHBH 1D7 34 1R5 | GHBH 002 34 1R7 |
Both blowers share a 2-inch inlet and outlet diameter, so the connection sizing is consistent between them.
Where Each Product Wins
- The Goorui GHBH 1D7 34 1R5 wins when your pressure or vacuum loop needs only the lower end of the flow range. It pairs the lower listed price with the same port setup and the same three-phase motor requirement.
- The Goorui GHBH 002 34 1R7 wins on air volume and pressure. It delivers a higher flow at a slightly higher pressure, giving it more headroom for demanding applications.
Product Notes
Goorui GHBH 1D7 34 1R5 Industrial Blower

At 150 CFM and 56" H2O pressure, this 2 HP blower is sized for moderate pressure or vacuum work. It uses a 2-inch inlet and outlet and is listed as a New unit. The upside is the lower list price: when 150 CFM is enough, you do not have to pay for the bigger unit's extra air volume. The limitation is capacity. If demand grows beyond this flow, you will need to step up to the larger model. That is not a quality concern; it is simply a flow ceiling. Pick it for jobs already defined around this airflow.
Goorui GHBH 002 34 1R7 Industrial Blower

The higher-rated GHBH 002 34 1R7 is the capacity pick: 221 CFM at 60" H2O pressure. The 2.8 HP rating gives it the stronger flow profile for larger pressure or vacuum loops. If your process moves more air or needs a bit more pressure than the lower-flow unit can deliver, this model gives you that margin. The limitation is that extra flow and higher power come with a higher list price. You pay for the added capacity, which is only worth it if you can actually use it. Choose it when airflow is the bottleneck, not when a lower-flow model would already do the job.
Final Choice by Use Case
Choose the Goorui GHBH 1D7 34 1R5 when your pressure or vacuum application is comfortably within the lower-flow model's rating and you want the $699 list price. Choose the Goorui GHBH 002 34 1R7 when you need the higher-flow model's capacity and extra pressure; its listed price is $989. If airflow is still an open question, the higher-flow blower gives you more room to grow, but it is the higher-cost choice.
