Portable dental air compressors provide the clean, oil-free air supply needed to effectively use a portable delivery system for mobile dentistry. These small air compressors are designed to travel and are often integrated into a transportable case with handles for easy packing and unpacking. They require a power supply and are often a heavy piece of equipment. Be sure to know how to properly transport the portable compressor, and practice the set up and pack up procedures before using a portable compressor in the field.
