3000 Series "Radial 12" Diaphragm air compressor

Dynaflo's 3000 Series Radial Compressor

The 3000 Series ‘Radial 12’ diaphragm air pump is a unique radial compressor that produces uniform, high flow at low pressure.  Our patented 3000 Series radial compressor utilizes a single central eccentric to drive twelve radially-oriented miniature diaphragm pumps. The result is a device that produces a smooth stream of air from a durable, lightweight body. This compressor was originally designed for medical ventilator applications but can be customized to suit additional applications.
