Frequently Asked Questions

Q1. What is the advantage of the 4L tank?

A: The 4L capacity provides significantly longer runtime compared to 1L, 2L, or 3L models, allowing you to work continuously without waiting for the pump to refill.

Q2. Can it run a framing nailer?

A: Yes, the 220W power and 4L tank make it highly suitable for framing nailers and other high-demand pneumatic tools.

Q3. Is it heavy?

A: While more powerful, it remains portable thanks to its compact footprint (275x255mm) and integrated handle. It's designed to be carried easily to job sites.

Q4. Does it come with a battery?

A: It uses standard 21V lithium batteries. Check the package details to see if a battery is included or sold separately.

Q5. How loud is it?

A: It is relatively quiet for its power class, especially with the vibration-dampening feet. However, high-power compressors naturally produce some noise.

Q6. Can I adjust the pressure?

A: Yes, it features a pressure regulator knob allowing you to set the exact PSI needed for your specific tool.

Q7. Is the hose replaceable?

A: Yes, it uses standard fittings, so you can upgrade or replace the metal braided hose if needed.

Q8. What surfaces can I use it on?

A: The rubber feet make it safe to use on wood floors, concrete, or even inside a van without scratching surfaces or sliding around.
