Harmony P4 HD

Harmony P4 HD – Faster, shorter, lighter.

The Harmony P4 HD – faster, shorter, lighter.
Faster: thanks to innovative double-stroke technology, the required vacuum is reached after just a few steps.
Shorter and lighter: direct integration into the socket eliminates additional adapters in favor of the structural height and overall weight. An external hose is no longer necessary.
