Let's start off with this crazy acranum VSBDC:
Variable Speed Boat Diving Compressor
An alternative to our floating systems, Brownie's has designed a Built-in-Boat System that operates on (2) supplied PC 1500 Odyssey AGM batteries AND will connects to your own boats alternator and continuously charge and operate while your vessel is powered up.
Included electronics allow the batteries to be automatically recharged from your running engine(s).
You can expect run times of 3 hours or more on a fully charged battery set.
Mounting holes are pre-drilled into the starboard base to assist in an easy installation.
A fresh air intake staff with dry top is mounted directly on the compressor head. But if fresh air is not immediately available where your mounting the compressor, Brownie's offers a Fresh Air Intake package that with help from a little polywire hose, draws air from a clean fresh air source and delivers to the compressor.
