Two products, both made for PVC and fabric stretch ceilings and for plasterboard: a regulated round diffuser, and a slot diffuser for longer runs.

Common questions
Match it to the duct or plenum spigot you already have: Vulkan 100 for a bathroom or WC extract, Vulkan 125 for most rooms, Vulkan 160 where the air volume is higher. Send us the duct size on WhatsApp and we'll confirm it.
Stock lengths are 1.0, 1.5, 2.0 and 2.5 m, stepping in 50 cm — 1.0 and 1.5 m have two Ø75 mm spigots, 2.0 m has three. Any other length can be made to order. Production takes 5–7 days and the diffuser arrives assembled and tested.
