The Mesh End (ME) is a duct accessory designed to protect HVAC and ventilation systems from debris, insects, and small animals while allowing airflow to pass freely. Manufactured from durable galvanised steel, it offers corrosion resistance and long-lasting performance. The mesh design ensures efficient ventilation and prevents blockages, making it...
The Blast Gate (BG) Damper is a duct control device designed to regulate or shut off airflow within ventilation and extraction systems. Manufactured from durable galvanised steel, it provides corrosion resistance and long-lasting performance. The sliding gate mechanism allows quick manual adjustment of airflow through individual duct branches, making it...
Circular attenuators are HVAC components designed to reduce noise transmission along ductwork while maintaining efficient airflow. Constructed from heavy‑gauge galvanised steel with internal acoustic lining (typically mineral wool or foam), they absorb and dissipate sound generated by fans and air movement. Ideal for commercial, industrial, and residential ventilation systems, circular...
The Circular Sound Attenuator (600 mm length) is designed to reduce noise in HVAC duct systems while maintaining efficient airflow. Constructed from durable galvanised steel with internal acoustic lining, it absorbs and dissipates fan and duct noise, creating a quieter environment. Ideal for residential, commercial, and industrial ventilation, it’s easy to...
The Back-Draught Shutter (BDS) is a mechanical device installed in ductwork to prevent reverse airflow when a fan or ventilation system is not operating. It automatically closes when air pressure drops, stopping unwanted drafts, heat loss, or ingress of dust and contaminants. Back-draught shutters are commonly used in HVAC supply,...
Multi-leaf Volume Control Dampers (VCD) are used in HVAC systems to regulate and balance airflow in duct networks. By adjusting multiple parallel blades, they allow precise control of air volume, helping achieve uniform distribution across different zones. VCDs are widely used in commercial, industrial, and large residential ventilation systems to...
The NCA Series 400 Fire Damper is a critical safety device for HVAC duct systems, designed to prevent the spread of fire and smoke through ductwork. It automatically closes when exposed to high temperatures, maintaining compartmentation and protecting building occupants and property. Commonly used in commercial, industrial, and residential buildings,...
he S900BA – NCA Series Volume Control Damper is designed for precise regulation of airflow in HVAC duct systems. With its robust multi-blade construction, it allows accurate balancing of supply or extract air, ensuring optimal environmental comfort and energy efficiency. Suitable for commercial, industrial, and large residential applications, this damper...
The Belimo Damper Actuator is a high-quality, reliable device designed to control the movement of HVAC dampers, including volume control and fire/smoke dampers. It converts electrical control signals into precise damper positioning, enabling accurate regulation of airflow for energy-efficient and comfortable ventilation. Belimo actuators are widely used in commercial, industrial,...
An Iris Damper is a type of adjustable airflow control device used in HVAC duct systems to regulate the volume of air passing through circular ducts. Its unique design allows precise throttling of airflow by rotating multiple radial blades, similar to a camera iris, making it ideal for balancing air...
The S100BGP – NCA Series 100 Plate Frame Fire Damper is a safety device designed to prevent the spread of fire and smoke through HVAC ductwork. It automatically closes when exposed to high temperatures, maintaining compartmentation and protecting building occupants and property. Ideal for commercial, industrial, and residential applications, this...
Master Flash Roof Flashings are versatile roofing accessories designed to provide a watertight seal around pipe penetrations, vents, and ductwork on pitched and flat roofs. They prevent water ingress while allowing for expansion and contraction of roof penetrations. Ideal for HVAC, plumbing, and industrial applications, Master Flash Roof Flashings ensure...
