Ventilation
Underground Mining Ventilation
Engineered ventilation infrastructure for safer underground operations
Maintaining critical airflow and pressure control
Effective ventilation is critical to every underground operation. It protects people, supports production and helps create safe and productive working environments.
Wilshaw designs, engineers and manufactures ventilation solutions that help mining operators control airflow, maintain ventilation integrity and optimise underground performance. Every solution is engineered to suit your mine’s ventilation network, operating conditions and long-term operational requirements.
Product features
Purpose-built solutions for underground ventilation control
Ventilation Control Systems
Engineered doors, regulators, airlocks and louvres designed to manage airflow, isolate ventilation circuits and maintain underground pressure control.
Pressure-Rated Infrastructure
Products engineered to suit varying pressure requirements while balancing safety, operational performance and practical installation.
Flexible Ventilation Networks
Pneumatic or hydraulic operated available in a range of configurations that seamlessly integrate with existing control systems.
Fit-for-Purpose Access Solutions
From vehicle airlocks to space-efficient roller shutters, all ventilation solutions are configured around access, space and airflow requirements.
PRODUCT RANGE
Ventilation infrastructure for every underground application
Manufactured to meet site-specific requirements, our range offers practical engineered solutions for airflow control, ventilation management and auxiliary ventilation infrastructure.
Drop Board Regulators
Fan Hangers
Roller Shutter
Airlocks/Man Doors
Louvres
Ventilation Doors
Pressure-rated performance for underground conditions
Wilshaw ventilation doors are available in both contra- and same-way opening, up to 5kPa.
Each system is engineered in accordance with relevant Australian Standards (AS 3990 and AS 4100), providing confidence in structural integrity, safety and long-term performance.
Flexible operation and control
Engineered for practical maintenance
Integrated airflow and pressure management
Drop Board Regulators
Adjustable airflow control for underground ventilation
Wilshaw Drop Board Regulators (DBRs) provide a reliable means of controlling airflow and resistance within underground ventilation networks.
Each regulator uses lightweight, removable steel boards that can be added or removed to adjust the opening as ventilation requirements change. Available for vehicle and non-vehicle access requirements.
Lightweight modular construction
Pressure-rated airflow control
Configured around access requirements
Fan Hangers
Engineered fan hangers for underground ventilation systems
Wilshaw Fan Hangers provide engineered support for secondary ventilation fans across underground mining operations and are designed to accommodate all commercially available underground mining fans.
Each hanger is designed and certified in accordance with Australian Standards (AS 4100), providing confidence in the safe support of critical ventilation infrastructure.
Multi-use with custom configurations available
Certified load capacity
Corrosion resistance and long-term durability
Roller Shutter
High-pressure roller shutters for underground access and isolation
Wilshaw Roller Shutters provide engineered ventilation, access and area isolation across underground mining operations.
Designed to achieve large clear openings within constrained excavation envelopes, they provide a space-efficient alternative to conventional ventilation doors where vehicle and equipment access must be maintained.
High-pressure and fire-proof performance
Space-efficient alternative
Engineered structural performance
Airlocks/Man Doors
Pressure-rated personnel access for underground ventilation
Wilshaw Airlocks and Man Doors provide safe and controlled personnel access through underground ventilation walls while maintaining airflow separation between ventilation circuits.
From standalone man doors for routine access to pressure-rated airlocks for higher-pressure scenarios, each system is engineered around ventilation pressure, access requirements and the surrounding infrastructure.

Louvres
Precise airflow management across underground ventilation circuits
Wilshaw Louvres provide adjustable airflow control across underground ventilation circuits, enabling airflow to be regulated frequently without opening or dismantling a Drop Board Regulator (DBR).
Available as standalone systems within ventilation walls or integrated into ventilation doors, louvres can be configured for variable airflow regulation, providing greater control over changing underground ventilation requirements.
