PLASTIC RECTANGULAR AND ROUND SYSTEM
A versatile plastic ventilation system that is ideal for installing air exchange systems in small and medium-sized residential or commercial premises. Thanks to a wide range of connection parts, it allows you to easily create various configurations of ducts in both horizontal and vertical planes, installing them in walls, under suspended ceilings or in an open manner.
Circular Duct
Rigid plastic circular duct for versatile ventilation installations. Made from durable, lightweight plastic that resists moisture and corrosion. Smooth interior walls minimize air resistance and noise. Easy to cut to custom lengths if needed. Connects seamlessly with other system components. Smooth white finish integrates cleanly with interior spaces. Available in three diameters (Ø100mm, Ø125mm, Ø150mm) and three lengths (0.5m, 1.0m, 1.5m) for flexible system design.
Circular Duct Joint
High-quality plastic circular duct joint designed for secure connection of round ventilation ducts. Features a simple snap-fit assembly system that requires no glue or sealants. Lightweight yet durable construction ensures easy installation and long-lasting performance. Also available with integrated flow control valve for precise airflow regulation. Available in three diameters (Ø100mm, Ø125mm, Ø150mm) as standard joint or with integrated valve for variable airflow control.
Circular Flange
Essential circular flange for secure wall and ceiling mounting of round ducts. Provides a clean, professional finish at duct termination points. Features pre-drilled mounting holes for quick installation. Creates a stable connection point for grilles, diffusers, and other terminal equipment. Multi-functional variant available combining mounting capability, duct connection, and airflow control in one component. Available in three sizes (Ø100mm, Ø125mm, Ø150mm) as standard flange or with integrated joint and valve.
Circular Duct Accessories
Comprehensive range of circular duct accessories for complete ventilation system installation. Includes professional-grade clamp sets (2 pieces) for securing connections, specialized couplers for joining fittings, flexible 0.5m connectors for vibration isolation and misalignment accommodation, and adjustable telescopic ducts (300-500mm) for precise length adjustment. All accessories feature tool-free installation and maintain optimal airflow efficiency. Available in three standard sizes (Ø100mm, Ø125mm, Ø150mm) with four accessory types: clamps, couplers, flexible connectors, and telescopic ducts.
Circular Elbow
Circular elbow fittings for directional changes in round duct systems. The 45-degree option provides gentle turns with minimal airflow resistance, perfect for noise-sensitive applications. The 90-degree elbow features optimized interior radius for right-angle turns while minimizing pressure loss. Essential for navigating walls, floors, ceiling joists, and obstacles. Durable plastic construction with smooth white finish. Available in three diameters (Ø100mm, Ø125mm, Ø150mm) and two angles (45° and 90°).
Circular T-Joint
T-shaped junction for branching circular duct systems into multiple pathways. All three ports are the same diameter for balanced airflow distribution. Smooth interior geometry minimizes turbulence and pressure loss. Essential for multi-room ventilation systems. Durable plastic construction ensures reliable long-term performance. Available in three configurations: Ø100-100mm, Ø125-125mm, and Ø150-150mm.
Round Duct Adapter
Reducer adapters for transitioning between different circular duct sizes. Gradual taper design minimizes turbulence and pressure loss during diameter changes. Essential for connecting different duct sizes in complex systems. Allows for system optimization by matching duct size to airflow requirements. Enables proper sizing of branch lines from main trunks. Smooth plastic construction ensures efficient airflow transition. Available in three size transitions: Ø150-100mm, Ø150-125mm, and Ø125-100mm.
Flat Rectangular Duct
Rigid flat rectangular duct perfect for low-profile installations and space-constrained areas. Ideal for under-ceiling runs and suspended ceiling installations. Smooth interior walls ensure efficient airflow. Lightweight construction simplifies overhead mounting. Rigid construction maintains shape without sagging. Clean white finish provides professional appearance. Can be trimmed to exact length if needed. Available in three rectangular dimensions (110x55mm, 220x55mm, 220x90mm) and three lengths (0.5m, 1.0m, 1.5m).
Rectangular Duct Connector
Standard connector for joining rectangular duct sections. Provides secure, airtight connection without reducing cross-sectional area. Smooth interior maintains efficient airflow. Essential component for extending duct runs. Also available as size transition connectors for connecting large trunk lines to smaller branch ducts with gradual transition design that minimizes airflow turbulence. Available as straight connectors in three sizes (110x55mm, 220x55mm, 220x90mm) or as transition connectors (220×90→220x55mm and 220×55→110x55mm).
Rectangular Elbow
Elbow fittings for right-angle turns and elevation changes in rectangular duct systems. Horizontal 90° elbows optimized for under-ceiling installations. Vertical 90° elbows designed for up-and-down transitions between floors or ceiling to wall. Unique adjustable horizontal elbow (110x55mm only) provides angle flexibility from 15° to 60° for custom routing. All maintain consistent cross-sectional area and minimize pressure loss. Available in three rectangular sizes (110x55mm, 220x55mm, 220x90mm) as horizontal 90°, vertical 90°, or adjustable 15-60°.
Rectangular to Round Transition
Versatile transition fittings for converting rectangular ducts to circular format. Available as elbow transitions (combining 90° turn with shape change), straight transitions in short or long versions for different space requirements, and flange-mounted transitions for wall/ceiling terminations. Smooth interior geometry maintains airflow efficiency. Ideal for connecting flat duct runs to round terminals, fans, or other circular components. Available in multiple configurations: elbow transitions (6 sizes), short straight transitions (3 sizes), long straight transition (1 size), and flange transition (1 size).
Rectangular Flange
Comprehensive range of rectangular flanges for wall/ceiling mounting and duct terminations. Basic flanges provide clean mounting base. Flanges with joint combine mounting and duct connection. Flanges with integrated valve add flow control capability. Flat connection flanges offer specialized mounting interface. All feature pre-drilled mounting holes for quick installation and create professional finished appearance. Available in rectangular sizes (110x55mm, 220x55mm, 220x90mm) with four flange types: basic, with joint, with valve, and connection flange.
Rectangular Duct Accessories
Complete range of rectangular duct accessories for professional installations. Includes robust clamp sets (2 pieces) for securing connections, specialized couplers for joining fittings without duct sections, flexible 0.5m connectors for vibration isolation, T-joints for branching systems, and standalone flow control valves for precise airflow regulation. All accessories feature tool-free or simple installation and maintain system efficiency. Available in three rectangular sizes (110x55mm, 220x55mm, 220x90mm) with five accessory types: clamps, couplers, flexible connectors, T-joints, and valves.
