Industry News 
Zhejiang Vermillion Import and Export Co., Ltd. manufactures air hydraulic jacks and air bag jacks for professional auto repair shops, garages, tyre and service bays, and industrial lifting tasks. The range covers 3 ton air bag jacks through 8, 12, 20, 22, 30, 35 and 50 ton air hydraulic models, so a single project can be equipped from light vehicle service to heavy machinery lifting without changing supplier.
We build these tools in Jiaxing, Zhejiang, on a full-chain production system that runs from raw material machining to finished product shipment, backed by an ISO 9001 quality management system and CE certification on core hydraulic products. As an Air Jack manufacturer, we supply distributors, brand sellers and engineering clients with standard models, OEM/ODM configurations and spare parts support.
How Air Jacks Work and Where They Fit
As a Air Jack manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
An air jack uses compressed shop air to raise a load, either through a reinforced air bag or through an air-driven hydraulic cylinder. Compared with manual pumping, the lift is fast and repeatable: the operator connects the tool to an air line, opens the valve and the load rises in seconds, then lowers under the control of a release valve. That behaviour suits high-turnaround environments where a vehicle or assembly must be raised and lowered many times per shift.
Typical applications include tyre service and wheel removal, brake and suspension work, under-vehicle inspection, body shop positioning, and lifting of machinery, skids and fabricated assemblies where a low starting height matters. Air bag models are chosen when the load needs a soft, wide contact patch and a very low collapsed profile; air hydraulic models are chosen when higher tonnage, a longer stroke or a more rigid lift point is required.

Air Bag Jacks and Air Hydraulic Jacks
Air bag models
Air bag jacks collapse to a very low height and spread the load across a wide, flexible contact area, which makes them effective on soft or uneven surfaces and under low-clearance vehicles. The 3 ton family is available as a standard single-bag unit, a wheeled version for mobile service, and dual-bag or triple-bag versions where additional stability is needed during lifting.
Air hydraulic models
Air hydraulic jacks combine an air motor or air-driven pump with a hydraulic cylinder, giving higher tonnage, a controlled stroke and a rigid lift point. They are the usual choice for truck, bus, fleet and industrial work, and for any task where the load must be held at height while mechanical stands are placed.
Specifications That Drive Selection
- Rated capacity — matched to the heaviest single-point load, with margin for off-centre loading.
- Collapsed and extended height — determines whether the jack fits under the load and reaches the required lift point.
- Air supply — working pressure and flow from the shop compressor, plus hose length and fitting type.
- Lift speed and control — air-driven raise with a release valve for controlled lowering.
- Base and saddle geometry — footprint stability and contact pattern on the load.
- Body construction — heavy-duty steel body with reinforced air bag or cylinder assembly.
Configuration and OEM/ODM Options
We configure air jacks around the working point, the available air supply and the way the tool will be used in the bay. Options we routinely discuss with project and product teams include:
- Logo and packaging customization, including laser marking, colour boxes, cartons and multi-language manuals.
- Structure and parameter adjustment — pressure, dimensions, appearance and operating layout adapted to regional standards and working habits.
- Exclusive new product development, from prototype design and sample production through to mass production and testing.
- Accessory and fitting selection to suit the air line, hose reel and storage arrangement in the workshop.
Air jacks are normally used alongside other lifting and support equipment. Our wider range includes the Jack family, Jack Stand support units for holding a raised load, and Vehicle Positioning Jack units for moving vehicles laterally in the bay.
Quality Control and Acceptance
Our factory operates under an ISO 9001 quality management system, with CE certification on core hydraulic products, and we implement full inspection through production to keep defective goods out of shipments. For air jack orders, the acceptance scope is agreed before production and typically covers rated capacity verification, air circuit sealing, raise and lower function, release valve control, surface and finish inspection, and packaging checks.
Inspection records, test results and certification documents are prepared with the shipment so that incoming inspection at the destination can be completed against the agreed specification.
Installation, Operation and Maintenance
- Connect to a clean, lubricated air supply within the rated working pressure; use a filter-regulator where the line carries moisture or oil carry-over.
- Position the jack on a firm, level surface and centre the load over the saddle or bag before raising.
- Raise the load, then place mechanical stands before any work is carried out underneath.
- Lower only through the release valve; never vent the air line to drop a load.
- Inspect the air bag, seals, hose and fittings at regular intervals, and replace worn parts from our spare parts supply.

Frequently Asked Questions
What capacities do your air jacks cover?
Our air jack range runs from 3 ton air bag models through 8, 12, 20, 22, 30 and 35 ton air hydraulic service jacks up to a 50 ton industrial air hydraulic jack. The correct model depends on the heaviest single-point load and the required lift height.
Should I choose an air bag jack or an air hydraulic jack?
Air bag jacks are best for low-clearance lifting on cars and light vehicles, especially on uneven ground, and are available in single, dual and triple-bag versions. Air hydraulic jacks are used where higher tonnage, a longer stroke or a more rigid lift point is needed, such as truck, fleet and industrial work.
Can you supply air jacks with our brand and packaging?
