Our Ventilation Expertise

Explore our specialist product range designed to meet the highest standards in safety, performance, and compliance. Whether you’re planning a new installation or upgrading existing systems, we offer reliable solutions tailored to your building’s unique needs.

Fusible Link-Only Smoke Ventilators

These louvre-blade ventilators are mounted on vertical or sloped roofs. Activated by a fusible link that melts at a set temperature, the blades open by gravity to release smoke and heat during a fire. They help maintain structural safety and provide clear escape routes. When closed, they’re watertight and customisable to different roof types and sizes. Their low-profile design ensures discreet yet effective performance.

Electromechanical Smoke Ventilators

Featuring louvre blades powered by actuators, these units open automatically when smoke is detected. A fusible link ensures operation if the actuator fails. They also support daily airflow, improving indoor air quality. With a sleek design and dual functionality, these ventilators are ideal for modern spaces needing both ventilation and fire safety.

Smoke Extraction Fan Systems

We offer ducted, vertical, and roof-mounted fans for effective smoke control. Ducted systems move smoke through fire-rated ducts, while vertical and roof fans provide simpler setups. Roof fans use wind-activated dampers to release smoke efficiently. These systems enhance evacuation safety and are ideal for commercial, industrial, and high-rise buildings.

Fire Dampers

Fire dampers block smoke and flames from moving through ventilation ducts. They close automatically via a fusible link or actuator during a fire. Easy to maintain and fully compliant with safety regulations, our dampers are available in multiple sizes to suit different ventilation systems.

Window Automation Actuators

Our actuators enable automatic window opening for fresh air or emergency smoke release. Options include chain, piston, spindle, and scissor drives, all compatible with various window types. Ideal for natural ventilation and fire response, they improve air quality while integrating seamlessly into building systems.

Natural Static Ventilators

These passive ventilators allow airflow without mechanical parts. Their curved design removes hot air and draws in cooler air naturally. Shipped disassembled to avoid damage, they’re quick to install and low-maintenance — ideal for buildings that need quiet, energy-free ventilation with architectural appeal.

Multi-Purpose Smoke Ventilators

Used for both natural ventilation and emergency smoke release, these ventilators open automatically when triggered by a fusible link. Suitable for ridge or sloped roofs, they blend clean aesthetics with reliable safety features. Their clip-on design speeds up installation and lowers costs.

Whirly Birds / Turbines

These wind-powered roof ventilators spin to expel warm air and draw in cooler air below. They require no electricity, need minimal maintenance, and suit most industrial and commercial roofs. With a 5-year warranty, they offer an eco-friendly solution for continuous airflow.

Fixed & Continuous Louvres

Our louvres allow steady airflow for intake or exhaust and fit neatly with cladding, brick, or glass. They improve air quality and support smoke ventilation without needing power. Their durable build and clean finish make them ideal for a variety of structures.

Smoke Curtains

Smoke curtains control the spread of smoke during a fire, protecting escape routes and limiting damage. Automatically deployed upon detection, they’re made from fire-resistant material. Static versions are also available for permanent use. A discreet and effective fire protection solution for open spaces.
