Manifold, 160mm Inlet x 12 Spigot 75mm EPP

Description

The Casavent MAN-160-75-12-V-EPP is an EPP distribution manifold that connects a 160mm inlet from the MVHR or MEV unit to twelve 75mm radial semi-rigid ducts. The larger 160mm inlet and higher spigot count suit medium-to-larger properties needing more distribution points than the 125mm/8-spigot manifold provides.

Moulded from Expanded Polypropylene, the manifold combines insulation, light weight, and good acoustic properties with corrosion-free durability, matching the rest of the Casavent EPP distribution range.

System Component This manifold is a system component — it connects a 160mm MVHR/MEV inlet to twelve 75mm radial ducts and does not include the ducting, air handling unit, or plenum boxes. These are sold separately.

Twelve-Way Distribution With twelve 75mm duct spigots from a single 160mm inlet, this manifold serves larger properties or higher room counts from one central hub, without needing a second manifold.	Larger Inlet for Higher Airflow The 160mm inlet supports greater total airflow into the manifold than the 125mm version, matched to MVHR/MEV units serving more rooms or 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.	Lightweight with High Stiffness EPP construction gives the manifold a combination of low weight and strong stiffness, easing handling during installation despite its larger size.
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.

What does this manifold connect?

It connects a 160mm inlet from the MVHR or MEV unit to twelve individual 75mm radial ducts, each running to a room's air valve plenum box.

Why choose this over the 125mm/8-spigot manifold?

The larger 160mm inlet and 12 spigots suit properties with more rooms or higher total airflow requirements than an 8-spigot, 125mm-inlet manifold can serve from a single unit.

What is the manifold made from and why?

Expanded Polypropylene (EPP) — insulating, lightweight with strong stiffness, good acoustic properties, and corrosion-resistant.

How is it fixed in place?

Using either screws and wall plugs, or an angle bracket and screw fixing set (sold separately).
