When you're shopping the compressors blowers air treatment category, the first fork in the road is whether you need air stored under high pressure or air moved in large volumes at low pressure. These two very different machines - the AllMetal 40 Gal gas-powered air compressor and the Goorui-USA 2.8Hp regenerative blower - illustrate that split. This head-to-head helps you decide which one solves your actual problem.
Quick verdict
The AllMetal is a portable gas-powered compressor with a 9HP engine and a 40-gallon tank, built to run tools far from an outlet. The Goorui-USA is a quiet, oil-free blower that turns a 2.8HP three-phase motor into a steady stream of airflow. If price is your first concern, the blower's $779 price is far below the compressor's $2,699.

Where each product wins
The AllMetal compressor is the better fit when you need high-pressure air to drive impact wrenches, spray guns, sandblasters, and nailers at a remote worksite. The long-running 9HP engine and tank give you stored force on demand.
The Goorui-USA blower wins for continuous, high-volume tasks like drying, aeration, ventilation, and vacuum hold-down. It does this with low noise and no oil changes.
AllMetal 40 Gal 9HP Gas Air Compressor 175 PSI 302cc OHV Portable Industrial
This machine is the definition of a mobile air supply. The Loncin 9HP OHV engine powers an 80% duty-cycle compressor, and the ASME-certified 40-gallon tank can sustain heavy use. At 250 pounds, it's meant to be towed or lifted onto a truck, not carried up stairs. Choose it if your jobs often leave you without grid power. The trade-off: you'll be buying gasoline, and because it's a tank compressor, it moves air at a relatively low rate compared with a blower - you won't use it to inflate a drying rig or aerate a pond.
2.8Hp Industrial air blower 220V-480V/3Ph. 150CFM, 84"H2O press GHBH 002 34 1R5
The Goorui-USA GHBH 002 34 1R5 is built for steady, oil-free service. Its cast aluminum housing and IP55 enclosure handle industrial environments, and the maintenance-free bearings are designed for long shifts. It can pull a vacuum as well as it can push air, so it suits vacuum tables and drying applications. If your shop already has three-phase power and you need reliable airflow, this is a low-cost workhorse. Its limitation is the power requirement: without a 220V-480V three-phase outlet, it sits idle, and its 84-inch water-column pressure isn't enough for pneumatic tools.
Final choice
- Off-grid job site, heavy tools, need stored high-pressure air? Choose the AllMetal 40 Gal gas compressor.
- Continuous airflow, on-site three-phase power, wanting lower upfront cost? Choose the Goorui-USA regenerative blower.
