Plenum for wall grilles
The OP100 plenum box is suitable for connection of rectangular wall grilles.
Unlike the ceiling plenum DP100, the OP100 has no protruding clinched ribs.
Instead, the sides are folded over to keep it as compact as possible.
- It’s available in three executions: Side entry, top entry or asymmetric top entry.
- Flow control is possible by means of a perforated damper in the inlet spigot.
