AC Industries

What AC Industries does

AC Industries is a family-owned Australian original equipment manufacturer specialising in seam-welded ventilation ducting systems and airflow control products for underground mining and tunnelling operations. Founded in 1991 in Tasmania as Allcover Products by Gordon Wigg and rebranded to AC Industries in 2013, the company consolidated its manufacturing footprint into a single three-line facility in Prestons, NSW, capable of producing up to 9 km of seam-welded ducting per day from polyethylene-based polymers. The product portfolio spans four core ducting brands (Mega-Dukt™, Turbo-Dukt™, Rhino-Fittings™, Twin-Dukt™), ventilation control devices (Parachute Stoppings, Retractable Blinds, Wall Kits, Tilt Doors), and the ROKFAST™ accessories range, with patented innovations including the Inline Smart-Choke™ and Lifter-Dukt™ system.

The business model is direct enterprise sales to mining operators combined with regional supply hubs in key mining geographies. AC Industries serves over 100 underground mines across 20 countries, providing technical services alongside hardware: airflow modelling, site visits, ventilation planning, system optimisation, and custom duct design. Pricing is quote-based, with an SOS (Ship Out of Stock) 1-5 day delivery promise on core stock items. The company's value proposition is anchored on low-leakage welded seams that reduce ventilation fan power consumption — reported to be up to 50% of total mine power — and on durable materials that extend service life (e.g., Rhino-Fittings rated 5-8x standard flexible ducting). The customer base is concentrated in a single vertical (underground hard-rock mining and tunnelling), exposing the firm to mining capex cycles, though the wide customer count and geographic diversification mitigate single-customer concentration.

Operationally, AC Industries holds ISO 9001 (quality), ISO 14001 (environmental) and ISO 45001 (occupational health and safety) certifications, and has run a 100% manufacturing-waste recycling programme since 2019. Distribution is a hybrid of direct-to-mine shipping from Sydney and regional supply hubs supporting local economies. The company remains privately held under the Wigg family with no disclosed external institutional investment or M&A activity across its 30+ year operating history.

Core offering

AC Industries designs, manufactures, and supplies seam-welded underground ventilation ducting systems, airflow control devices, and mining accessories for the global mining and tunnelling industry. Its core ducting brands (Mega-Dukt™, Turbo-Dukt™, Rhino-Fittings™, Twin-Dukt™) are complemented by patented ventilation control innovations (Inline Smart-Choke™, Lifter-Dukt™) and a RokFast™ accessories range. Products are made in-house at the Prestons, NSW facility and sold direct to enterprise mining customers across 20+ countries.

Product overview

AC Industries is a specialist manufacturer of underground ventilation ducting systems and flow control solutions for mining and tunnelling projects. The product portfolio is organized around four core ducting system brands: Mega-Dukt™ (medium grade), Turbo-Dukt™ (high performance with K-Factor coating), Rhino-Fittings™ (ultra heavy-duty flexible), and Twin-Dukt™ (low profile/high clearance). These core systems are complemented by ventilation control products including Inline Smart-Choke™ and Lifter-Dukt™ System for airflow management, plus Parachute Stoppings, Retractable Ventilation Control Blinds, Ventilation Wall Kits, and Ventilation Tilt Doors for physical air control. The ROKFAST™ accessories sub-brand offers cable management and duct joining solutions, while ROKSOK™ Blast Hole Liners, TUFSAK™ Tool Bags, and DUKT-GUARD™ Protection Sheeting round out the mining services offering. All products are manufactured in-house at the Sydney facility with three production lines capable of producing 9km of seam welded ducting daily.

Products and services

• Mega-Dukt™ Quality medium grade ventilation ducting system with low leakage seam welded construction using polyethylene-based polymers, available in diameters from 300mm to 2800mm. Proven in over 75 underground mining operations globally over 20+ years.
• Turbo-Dukt™ High-performance ventilation ducting system engineered with low resistance (K-Factor) coating and low leakage seam welded construction using ultra-high wear material polymers that maintain lightweight properties, available in diameters from 300mm to 2800mm.
• Rhino-Fittings™ Ultra heavy-duty flexible duct fittings system that can withstand very high operating pressures and greater wear and tear, reported to last 5-8 times longer than standard flexible ducting. Available in diameters from 300mm to 2400mm as an alternative to high cost rigid or semi-rigid ducting.
• Twin-Dukt™ Low resistance welded low profile (oval) ducting system providing up to 25% extra clearance while maintaining good airflows, designed to reduce tunnelling costs by minimising tunnel depth profiles. Available in sizes from 610mm to 1600mm round equivalent.
• Inline Smart-Choke™ Integrated ventilation control device for fast and effective control of ventilation air, part of the Turbo-Dukt™ system. Can be activated by an operator on the ground in seconds to open and close ducting and direct air to active headings, providing 100% effective seal with significantly less wasted leakage.
• Lifter-Dukt™ System Secondary ventilation system designed to keep deflated ducting 'lifted' to its inflated depth, allowing mines to turn fans off and reduce power cost when mining areas are inactive. Addresses ducting sagging by an extra 60% when deflated.
• Parachute Stoppings Temporary vent control devices available in coned and flat configurations. Coned parachutes provide up to 95% effective seal for sealing off old stopes and creating temporary vent circuits; flat parachutes seal existing vent controls to reduce leakages.
• Retractable Ventilation Control Blinds Robust ventilation control option for areas requiring vehicle access. Seals against formed bulkhead under pressure and rolls up/down via manual winch, rated for pressures up to 1.5kPa, available in standard sizes from 4m x 4m to 5.2m x 5.5m.
• Ventilation Wall Kits Fast and simple formwork for fabricating underground vent walls using a tek screw together design that removes the need for Jumbos or Air legger Drills. Typically erected within 2-3 hours by operators; available in standard sizes from 4m x 4m to 5.5-6m.
• Ventilation Tilt Doors Engineered quick cycle door designed for frequent opening and closing, available with automated pneumatic or hydraulic activation for underground mine ventilation circuits.
• RokFast™ Accessories Quality range of mining services accessories including cable hanging straps, cable hanging hooks, vent securing ratchet straps, vent duct joining clips, duct repair items (marline twine and repair needles), TUFSAK™ tool bags, ROKSOK™ blast hole liners, and DUKT-GUARD™ protection sheeting, designed for underground miners.
• ROKSOK™ Blast Hole Liner High-strength woven blast hole liner for underground mining. Anti-static treated, water-resistant, and lightweight for ease of application. Minimizes explosives leaching, promotes consistent blast performance, and creates a moisture barrier; available in diameters from 45mm to 300mm.
• TUFSAK™ Tool Bags Premium tool bags built for underground mining conditions, trusted by miners for over 15 years. Includes MTB01 General Purpose Tool Bag (250mm x 480mm x 200mm), MTB01M Tool & Crib Bag (250mm x 370mm x 120mm), and FTB01 Premium Fitters & Electricians Tool Bag (275mm x 540mm x 280mm), with reinforced structural bases and high-visibility stripes.
