Import Arc-500 Air Reverse Circulation Drilling Rig — Buy in wholesale FOB from Supplier in China

The ARC-500 Air Reverse Circulation Drilling Rig from Huaxiamaster is an air-powered RC drilling system built for mineral exploration and production drilling where sample integrity and penetration speed matter. The rig uses compressed air to drive cuttings up through an inner tube to the surface, eliminating the need for fluids that can contaminate samples or complicate disposal. Its working principle relies on a pneumatic hammer or tricone bit at the drill face, with dual-wall drill rods creating a closed loop that returns chips to a cyclone for collection. The ARC-500 designation typically indicates a 500-metre depth capacity in standard ground conditions, though actual performance depends on rock hardness, air compressor output, and rod diameter.

The mast and feed system are built around a robust pullback structure, with typical RC rigs in this class offering pullback forces in the 15-25 tonne range and rotary head speeds adjustable to match formation types. Air consumption is substantial, with standard operation requiring a dedicated compressor delivering 800-1200 cfm at 150-200 psi, depending on hole diameter and depth. The rig is trailer-mounted or skid-mounted for mobility, with a compact footprint suited to remote sites where road access limits larger equipment. Standard tooling runs 4-inch to 6-inch reverse circulation bits, with API thread connections typical for the drill string. The control system is pneumatic and hydraulic, with manual overrides for critical functions.

Primary buyers include mineral exploration contractors, mine site development teams, and geotechnical consultants working in hard-rock terrains of Africa, Central Asia, and South America. The RC method excels in consolidated formations where diamond drilling is too slow and rotary air blast gives poor sample recovery. Typical applications include grade control, resource definition, and water well drilling in fractured rock. Packaging is usually in containers or flat-rack for sea freight, with partial disassembly of the mast. The supplier lists flexible MOQ and FOB or CIF shipping terms, though buyers should confirm exact quantities, packaging details, and Incoterms directly with Huaxiamaster before finalising any order.

OOO «Шандонг HUAXIAMASTER Машиностроительная Группа» is headquartered in Jining City, Shandong Province, China, operating from the Huaxiamaster Industrial Park in the High-Tech Zone. The supplier is listed at harbor trust tier with a 0.00 response rate and zero recorded response hours, which indicates no verified buyer engagement through the platform. Its organic supplier tier suggests it was indexed through standard marketplace registration rather than a paid or promoted placement. The address points to a dedicated industrial park, though this does not independently verify production scale or in-house manufacturing depth.

The listing positions Huaxiamaster as a supplier of industrial-grade drilling equipment with emphasis on environmental benefits of air RC technology and transportability to remote sites. No verified certifications, specific factory floor details, annual output figures, or client references are present in the source data. Buyers should conduct direct due diligence on production capacity, after-sales parts availability, and commissioning support, as these are not substantiated in the profile. The supplier mentions flexible MOQ and standard shipping terms, but exact figures require confirmation.
