DOA

Product Type: Diaphragms

Description

If you need a small, quiet source of vacuum or pressure, you'll find the unit for your application in the Gast line of oilless Diaphragm air compressors and vacuum pumps, which come in standard, twin, and miniature styles. Plastic component construction on the miniature pumps makes them especially compact and lightweight...ideal for light-duty applications.

Air flow capabilities for the entire line range from .65 lpm up to 3.8 cfm (6.5 m3/h), vacuum up to 29 in. Hg (31 mbar), and pressure up to 60 psig (4.2 bar). Electric motors are available in dual frequency, shaded pole, and permanent split capacitor (psc) versions as well as AC multi voltages for worldwide applications, plus 4-24 volt DC options on the miniature styles. Horsepower range from 1/16 to 1/2 HP (0.05 to 0.37 kW) on the standard size models.
