Technical Data
Frequently Asked Questions
How much more air does 4 HP give versus 3 HP at 300 L?
480 L/min vs 390 L/min — about 23% more intake. That's the difference between running one impact wrench and running an impact wrench plus a tire inflator at the same time.
Is 300 L enough for a 4 HP pump?
For intermittent use (2–4 hours per day) yes — duty cycle stays under 60%. For heavy continuous use consider the 500 L version to keep the pump cooler and extend service life.
Can I use it with a paint spray gun?
Yes, for small to medium HVLP guns. Add an inline oil-water separator and a 5 µm filter — piston pumps carry some oil mist that will contaminate paint if unfiltered.
