The Senator CM15 is a permanent magnet variable speed rotary screw air compressor that integrates a screw air-end, 450 litre air receiver, refrigerant dryer and dual filtration into one compact 4-in-1 air station. Delivering 1.29–2.45 m³/min (45–87 cfm) at 8 bar, the direct-drive, belt-free design keeps noise to 71 dB(A) and vibration low, with a soundproofed cabinet and anti-vibration mounting that make it safe to install directly on the workshop floor without a separate plant room. It suits Australian industrial, workshop and manufacturing operators who need a reliable, plug-and-play compressed air supply with minimal floor space and installation cost.
