HDPE Fresh Air Corrugated Pipe

HDPE Fresh Air Corrugated Pipe — Flexible Double-Wall Ducting for Residential Ventilation Systems

The HDPE fresh air corrugated pipe is the backbone piping of modern residential fresh air (MVHR) systems. It uses a double-wall corrugated structure: a smooth inner wall keeps air resistance low, while the corrugated outer wall gives the pipe flexibility and crush resistance. One coil of pipe replaces dozens of rigid fittings, which means fewer joints, less air leakage and much faster installation.

As a professional HVAC ventilation products supplier, GUANDE keeps this pipe in regular stock in Ø75 / 110 / 160 / 200 / 250 mm, ready for wholesale orders and project supply. OEM and ODM service is available.

Key Features

• Double-wall corrugated structure — smooth bore for low air resistance, ribbed exterior for strength
• Highly flexible — bends by hand without elbows, follows beams and corners easily
• Antibacterial and odor-free — food-grade HDPE material, moisture-proof, no secondary pollution to indoor air
• Quick-connect compatible — works with our push-fit tees, couplings and reducers for tool-free assembly
• Long coils — supplied in coils to minimize joints and leakage points

Technical Specifications

Typical Applications

• Top-feeding (ceiling) fresh air distribution in apartments and villas
• Branch piping from the heat recovery unit to air distribution boxes
• Connection between plenum boxes and ceiling air diffusers
• Retrofit projects where rigid ducting is hard to route

Matching Fittings

This pipe pairs with our full quick-connect fitting family: oblique tee fittings, straight couplings, reducers, ABS air distribution boxes and ceiling air diffusers. All sizes share the same push-fit interface, so a complete system can be assembled without glue or tools.

FAQ

Q: Can the pipe be embedded in concrete or screed?
A: HDPE corrugated pipe is mainly used for open routing in ceilings, voids and service gaps. For screed-embedded (underfloor) runs we recommend our insulated flat duct series designed for that purpose.

Q: Does the smooth inner wall reduce airflow?
A: No. The inner wall is smooth specifically to keep pressure loss low; the corrugation is on the outside only.

Q: What is the MOQ and delivery time?
A: We hold regular stock for all five diameters. Contact our sales team for current stock, wholesale pricing and lead time for your market.
