Not all applications use or need large amounts of compressed air for part processing but a Clean Production  type machine is still required.  Equipment used on a daily basis requires negative pressure dust collectors, ergonomic designs, blower silencer and micro abrasive delivery for small part processing.  Media Blast makes this type of equipment in siphon, direct pressure and even a model allowing you to add the abrasive delivery type.
This link will take you to the Micro Models; PrecisionEtch, PrecisionBlast and MicroBlast models.

Industrial Machines, Macro Types, are designed to operate using large volumes of compressed air.  This type of machine will produce the fastest cleaning and the most daily production.  Features include production type dust collectors for fast cleaning and a long list of available options to help with part handling and abrasive delivery. This type of equipment is used when reduced part processing time equals money saved.  Media Blast offers many different models in the siphon and direct pressure types.
