We have developed a laboratory-based, test bench robotic system that drives an active drill into concrete while simultaneously measuring these health-related exposures and productivity. The measurement methods follow guidelines from national and international standards.
[pdf] Highly energy saving Comparing to non-variable speed screw air compressor, its average saving rate can be up to 50%; Super air displacement, its frequency is variable from OHz to 300Hz and the air displacement can be increased by as much as 28%; High efficient motor (IPM), its efficiency is up to 94.5%, reaching the rating of IE4.
