Since clean oil matters, the VPX7 features a large oil reservoir window to give you an instant indicator of the condition of your oil and system. It also features our RunQuick� Oil Change System that lets you change oil without powering down and without losing vacuum. You won�t make a mess. Our new removable oil window makes it easy to clean and easy to see operational lights regarding gas ballast and cold start. We designed the VPX7 to handle the demands of any job site. It�s light enough to be carried anywhere and its extra-wide base means it won�t tip or spill oil once you get it there. Also, it has four in-line ports, so you�ll have plenty of room for running multiple hoses without tangles or clutter - port sizes: (1) 1/4", (2) 3/8", (1) 1/2". The VPX7 features a 3/4 HP DC Motor, and has a 10 CFM flow rate with 15 microns ultimate vacuum.
