Industrial Screw Air Compressor
If you've ever worked on a tunnel site, you know the headache: the drills stop, but the compressor keeps howling at full power, wasting money. Or worse, the pressure drops just when the rock gets tough, and your crew is left standing around.
We built this Industrial screw air compressor specifically to handle those messy, high-pressure environments where "standard" gear fails.
Jining Dongtai Lite Engineering Machinery Co., Ltd. is one of the leading manufacturers and suppliers of industrial screw air compressor in China. With abundant experience, we warmly welcome you to buy customized industrial screw air compressor made in China here from our factory. Good service and quality products are available.
Why this works on a real job site
It stops burning cash when the drills stop.
Instead of running at 100% all day, the Permanent Magnet (PM) motor slows down or speeds up instantly. If your team is changing bits or taking a break, the machine sips power. It's significantly cheaper to run than a fixed-speed unit, especially in tunnels where the workload jumps around constantly.
01
Move it, plug it, start drilling.
We didn't just put a handle on it; we built it onto a reinforced trailer chassis. You can hitch it to a truck, pull it to the next tunnel section, and have air running in minutes. No need to layout kilometers of expensive piping.
02
Built for "Mining Dust," not a clean lab.
The seals and cooling system are beefed up. It's designed to suck in dusty, gritty air and keep the internal "screw" protected. It's a bit heavy because of the extra steel reinforcement, but it won't rattle apart when the ground starts shaking.
03
Keep an eye on it from your phone.
Through the i-Kaishan app, you can see the pressure and temperature without walking over to the machine. If something's getting too hot or a filter is clogged, you get a ping. It catches small issues before they turn into a 3-day shutdown.
04
Steady 8-bar pressure.
It holds a steady 8kg of pressure even when the demand spikes. Your pneumatic tools will last longer because they aren't fighting constant pressure swings.

FAQ: The stuff you actually need to know
Q: Is the variable frequency (VSD) really worth the extra cost?
A: Honestly, if you are running 24/7 at a constant load, a basic machine is fine. But in mining and tunneling, your air demand is all over the place. In those cases, the power savings usually pay for the machine's price difference within the first year.
Q: What's the catch with the Permanent Magnet motor?
A: The motor is incredibly efficient, but it hates extreme heat (above 50°C) for long periods. We've oversized the cooling fans to handle this, but you still need to make sure the ventilation isn't blocked by debris.
Q: How often do I really have to change the oil?
A: Usually every 4,000 hours. If you're in a particularly dusty tunnel, check the air filter every week. It takes five minutes, and it's the best way to make sure the Industrial screw air compressor reaches its 10-year lifespan.
Q: Does it come with the trailer?
A: We have both skid-mounted (stationary) and trailer-mounted versions. The trailer version is the favorite for road and bridge work because of the high-clearance tires, but it does take up a bit more floor space.
Q: Who is this for?
A: Tunnel Contractors: If you need to move the air source as the face advances.
Well Drillers: If you need reliable, high-volume air in remote areas.
Site Managers: Who are tired of seeing a $5,000 electricity bill every month.
The machine is solid, the tech is smart, and it won't quit when the dust kicks up. If you need the actual dimensions to see if it fits on your truck, just send us a message.
