- This design combines the light weight and compact size of the diaphragm unit with the vacuum capabilities of reciprocating piston units.
- Vacuua to 27.5 in. Hg are available with a single stage; two-stage units can provide vacuums to 29 in.Hg. Air flows, however, are limited, with the largest model available today (a twincylinder model) offering only 2.7 cfm.
