The Casavent MAN-200-75-10-H-EPP is an EPP horizontal pass-through distribution manifold that connects a 200mm inlet to ten 75mm radial semi-rigid ducts. Unlike the vertical manifold range, this pass-through design arranges its spigots along a single horizontal row, suited to shallow ceiling voids or installations where a low-profile manifold housing is required.
Moulded from Expanded Polypropylene, the manifold shares the same insulating, lightweight, and corrosion-free construction as the rest of the Casavent EPP distribution range, sized for the larger airflow volumes a 200mm inlet supports.

System Component
This manifold is a system component — it connects a 200mm MVHR/MEV inlet to ten 75mm radial ducts and does not include the ducting, air handling unit, or plenum boxes. These are sold separately.
Horizontal Pass-Through Layout
Spigots are arranged along a single horizontal row rather than a compact block, giving a lower-profile housing that suits shallow ceiling voids where headroom for a vertical manifold is limited.
Ten-Way Distribution
With ten 75mm duct spigots from a single 200mm inlet, this manifold serves larger properties or higher room counts, positioned between the 8-way and 12-way vertical manifolds in the range.
Sized for 200mm Inlet Airflow
The 200mm inlet supports higher total airflow into the manifold than the 125mm or 160mm versions, matched to MVHR/MEV units serving larger floor areas.
Insulating EPP Construction
The Expanded Polypropylene body (λ = 0.0038 W/(m·K)) provides thermal insulation around the ductwork hub, reducing condensation risk.
Good Acoustic Properties
The closed-cell EPP structure offers useful sound-deadening properties, helping reduce fan noise transmission along the ductwork.
Corrosion-Free
Unlike galvanised steel manifolds, the EPP body is immune to corrosion, giving long service life in loft installations.

Airflow & Pressure Performance
Approximate system performance for this spigot configuration (based on the manufacturer's equivalent pass-through manifold family): around 7 Pa pressure drop at 300 m³/h total airflow.
What does this manifold connect?
It connects a 200mm inlet from the MVHR or MEV unit to ten individual 75mm radial ducts, each running to a room's air valve plenum box.
What does 'horizontal pass-through' mean?
Rather than a compact block with spigots on multiple faces, this manifold arranges its spigots along a single row, giving a shallower, lower-profile housing suited to tight ceiling voids.
Why choose the 200mm inlet over 125mm or 160mm?
The 200mm inlet supports higher total airflow, suiting larger properties or higher-capacity MVHR/MEV units where more air needs to pass through a single manifold.
What is the manifold made from and why?
Expanded Polypropylene (EPP) — insulating, lightweight with strong stiffness, good acoustic properties, and corrosion-resistant.
