This prototype blower is of a multistage design. Need to move more air? Just add stages. I’ve seen the prototype from 3 stages, to 10 stages.
Accepts 1/2″ Evergreen Tubing in and out, and comes with 4 stages. Additional sets of 4 stages available. Supplied with flange rings for use in plant, or use as delivered as a great flat car load, and simply make wooden block off plates for the inlet and outlets from 0.010 or 0.020″ wood sheet. Supplied with electric motor for use in plant.
