compressor/vacuum combined pump?

[altaboy]

Hi gang,

Picked up the "mother of all zip lock bags"? They have ports where you hook up a vacuum cleaner and greatly reduce volume. great for those non-down sleeping bags. Double bonus: another added protecton against moisture.(https://www.amazon.com/gp/product/B01LYMYTR3/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Coincidentally, I am in the market for an air compressor.

The question: any one know of a "combined compressor/vacuum" unit? the ziplocks come with a hand vacuum pump that works, put a dc driven unit, would be much faster.

If no, anyone recommend a vacuum pump/compressor mod kit for the typical overlanding type compressor?

Look into a pneumatic vacuum gun. Very simple device, just a valve that releases compressed air through a tube producing a Venturi effect and therefore vacuum. Only issue may be the volume of air required to function properly so you will need a larger compressor.
