Thank you for the post,

First, please stop posting links to your website (video production, etc.). If you're trying to obtain backlinks for SEO purposes, this is a black hat practice and something we don't tolerate here. Please do NOT post links or your account will be deleted.

That being said, you have either defective Valves in the Head, Gaskets or both. The Valves are the main pressure component that builds pressure in an air compressor so if the unit will run but won't build up much pressure, the problem lies in the pump.

Otherwise, check for major air leaks by spraying soapy water on all of the fittings and areas where air could escape. My money is on the pump Valves, Gaskets and/or Rings being defective, however.
