Hand Pumping Question

i also own a Yong Heng for about a year now, I top off a huge109cuft carbon fiber tank from around 2900 to 4300 psi in 30-40 minutes. Its a 220v unit and i had to change the plug to fit US standards and bought a tile wet saw water pump from home depot to keep it cool i also bought one of those gold filters to dry the air total price was under 400.00 not including the cf tank.
