The multi-stage ZL series is a high-efficiency vacuum generator, which
operates at 150% efficiency (compared to about 40% for other units).
For each scfm of compressed air it consumes, the ZL generates an
incredible 1.587 scfm of suction flow. The ZL is available with a
built-in vacuum switch with digital readout for design flexibility.
Other features include built-in suction filter, exhaust silencer, and
one-touch tube fittings. Its' compact design allows for mounting from
three sides.
