Duct Your OptiClimate From Outside the Grow RoomThe Plenum Box is a tough insulated case that fits to the back of an OptiClimate Pro 3 air conditioning system, over the rectangular filter. With it fitted you can site the OptiClimate outside the growing space entirely and duct the air in and out – useful when floor space is tight, when noise matters, or when you want the unit somewhere you can service it. Paired with a 3-way valve it also lets a single OptiClimate handle two separate rooms. Four perforated, pre-cut holes mean you can bring ducting in from whichever angle suits the room, and the case is available in sizes matched to each OptiClimate model.Key Benefits Site the OptiClimate outside the grow room and pull the air through ducting instead Split one unit across two rooms when used with a 3-way valve Four pre-perforated holes so ducting can enter from any angle Insulated construction that keeps conditioned air where it should be Model-matched sizes for the Pro 3 3500, 6000, 10000 and 15000 How to Use Pick your holes first: decide which of the four pre-perforated sections you need and cut them out with wire cutters before the box goes on the unit Fit your flange (available separately) using Tek screws Hook the box onto the back of the OptiClimate over the rectangular filter and secure it with duct tape Attach your ducting with a duct clip – 250mm for the Pro 3 3500 and 6000, 315-350mm for the Pro 3 10000 and 15000 Choose ducting to suit: combi ducting is sturdier than plain aluminium and copes with humidity better than acoustic ducting Technical Specifications Fits: OptiClimate Pro 3 air conditioning systems Construction: Insulated case, pre-perforated aluminium Duct openings: Four perforated (pre-cut) holes Ducting - Pro 3 3500: 250mm Ducting - Pro 3 6000: 250mm Ducting - Pro 3 10000: 315-350mm Ducting - Pro 3 15000: 315-350mm Fixing: Flange and Tek screws (flange sold separately), duct tape, duct clips
