    FAQS :

    Can the psi be set to a continuous 40 psi to blow out RV water lines for winterization?

    Answer: Yes, using an external regulator. Go to t=40 seconds in Google RV Geeks Winterizing to show their solution when utilising a 150 PSI Viair compressor to blow out their RV water lines. (Sorry, Amazon won't let me post the link here).

    Is the hose that comes with it screw on or something else?

    Can the hose be modified to incorporate a screw-on valve connector?

    It comes with a one-year warranty! However, there are no refunds. How does the warranty function?

    Answer: I'm not sure. It's the policy of the seller. You may contact the vendor via email to obtain more information. Continue to click on the seller's product section until you find the contact link. This is a heavy-duty pump, by the way. I had a tyre that was about 30# and it quickly increased to 36#. The VIAIR 300P comes highly recommended by me.

    I need to 'top off' my rv tyres to 125 psi. Does anyone have any experience with this compressor? Please do not respond if you do not know.

    Because the 300P's gauge only shows up to 100psi, we recommend the 400P-Auto or 400P-RV.

    Does this also inflate your tyres?

    Answer: This does not deflate the tyres; the reed valves within the compressor head prevent backflow quite effectively. Using the gauge removed from the yellow hose will not allow air to escape because the gauge itself contains a check valve. You can bleed air using the button on the rear, but it will be excruciatingly slow.

    I observe contradictory dimension information. Please confirm the height, width, and length of the compressor, not its packaging.

    It is 13 1/4 inches long, 5 7/8 inches wide, and 9 inches tall, including its mounting base. Alone, the compressor is 13 inches tall, 4 3/4 inches broad, and 7 7/8 inches wide.

    Does anyone who purchased this within the last two months know if it comes with the attachments, since I am concerned that it used to but no longer does?

    It came with a carry bag, hose, screw-on inflator with pressure gauge, and a few more components when I purchased it a month ago.

    What is the duty cycle (in percent)?

    I have always had greater than 80% duty cycle from my compressor (8 min into 4 tyres in under 10 minutes). I have not yet thermally shut it down. The primary outlet hose becomes hot, but the engine and compressor do not become excessively warm. Description: Viair 300p vs Smittybilt 2781
