Frequently Asked Questions

Why choose a Yanmar diesel compressor?
Diesel drive lets you fill high-pressure cylinders where electrical power isn’t available or reliable — remote sites, standby use, and marine applications — while the Yanmar engine provides dependable continuous-duty operation.

What pressure and flow does it deliver?
It delivers up to 5000 PSI at a charge rate of 10.8 SCFM (18.4 m³/hr).

Is it built for continuous use?
Yes. The DY5K is a continuous-duty compressor designed for heavy, ongoing filling rather than occasional single fills.

Can it charge storage banks and cascade systems?
Yes. Its output suits charging high-pressure storage and cascade systems as well as filling cylinders directly. If you’re weighing direct filling against adding storage, see our guide on cascade air systems.

Don’t forget to look at our accessories and consumables to keep your Max-Air 90 running its best.
