Roof Top HVAC System #2 ~ HO Scale

Price: $49.50

Newly Released... The Roof-Top HVAC System #2 is now available.

The Roof-Top HVAC System #2 is a newly designed set of 3D-printed / resin-cast components to make up this detail assembly kit.

This new HVAC System kit is a collaboration between MicroMimesis, Rusty Stumps Scale Models, and Rail-Scale-Models with the intent to offer another interesting roof-top detail for scale structures.


This new version is a larger system with more components, and offers great flexibility as to how to lay out the components to fit the roof-top size and shape of your scale structure.  Included in the kit are all the components needed to build the HVAC unit layout as shown in the photo.  Follow the assembly instructions for the standard layout, or make variations as you like. 

Kit includes the four large HVAC system components, all fittings, and all styrene tubing.  Cut tubing to length as described in the instructions or modify lengths to fit your structure roof-top space.  There are angle styrene strips also included to create support brackets for the ductwork.  The system can be placed on the roof of any size industrial building.


There is a short overview of the assembly configuration included in the kit box, and Ed Traxler at MicroMimesis created a great on-line instruction set for assembly of this kit which can be found at the following link:



NOTE:  Figures, vehicles, ground scenery, railroad track, and general diorama construction materials shown in model photos are not included in the kit.  Pictures shown are of the pilot model construction;  production models might vary slightly.
