Auxiliary accessories: E16.11 tubular silencer Φ160, E75.01-9 air distribution plenum box, HF series return air box Φ100/Φ150All accessories adopt snap-on quick connection design without glue, good air tightness, anti-aging, low air resistance, easy on-site installation.

MENRED full set fresh air system accessories form a complete ducted ventilation matching solution, specially designed for central HRV/ERV heat recovery fresh air units. The core pipeline adopts high-density HDPE double-wall corrugated structure, with advantages of high flexibility, low wind resistance, shock absorption and noise reduction, avoiding resonance noise caused by rigid metal ducts during air supply. Multiple standard diameters Φ75, Φ110, Φ160 cover small apartment to large villa engineering demands.

The supporting manifold and air distribution plenum box solve the problem of messy pipeline layout of traditional fresh air systems. DN75.8/8T 8-way branch connector can evenly divide fresh air to each independent room, balance air volume of each branch and eliminate short-circuit airflow. All pipe connecting fittings (tee, elbow, reducer, straight connector, quick flanged joint) use integrated snap locking structure, no adhesive required, greatly shortening construction time and ensuring long-term air tightness without air leakage.

Complete fixing accessories including PE suspension clips, multi-adjustable pipe hangers and silicone sealing rings provide stable pipeline suspension and interface sealing. The silicone sealing rings fit perfectly between pipe and fittings to block air leakage, improve overall fresh air system efficiency and reduce unit energy consumption.

For indoor and outdoor air terminals, the product line covers two categories: indoor ceiling vents and outdoor weatherproof outlets. T2/T3 series ceiling mounted air vents adopt beautiful round embedded design, with adjustable air volume, matching various interior decoration styles; OA3 stainless steel outdoor air outlets have built-in anti-insect net and rain shield to prevent rainwater, mosquitoes and small animals from entering the pipeline. HF series return air boxes concentrate indoor exhaust air, cooperate with HRV exhaust pipeline to realize full-space circulating ventilation. E16.11 tubular silencer effectively absorbs airflow noise inside the duct to deliver quiet fresh air environment.

All raw materials are food-grade anti-aging HDPE and thickened stainless steel, resisting high temperature and cold, not easy to deform or crack for long-term buried ceiling use. Every accessory has unified model number and standardized packing specification for convenient engineering bulk purchasing and inventory management. The whole series passes CE and RoHS environmental safety certification, no harmful volatile substances, safe for household closed indoor environment. Stable mass production capacity supports global ventilation project contractors and fresh air equipment distributors for one-stop matching procurement, and accepts customized size and packaging services for large orders.
