Powerex BT012001AV 3VX Belt for their 3hp and 5hp Oil Free Scroll Air Compressors without Enclosure
Powerex recommends changing this belt every 5,000 hours of operation or once per year. The tension of the V-belt should be adjusted during the initial stage and inspected every 2,500 hours afterwards. Proper belt tension is just enough to prevent slippage.
Most Powerex compressor systems required (2) belts per scroll compressor pump, so if you have a duplex scoll system with multiple internal pumps you may need to order Qty 4 at a time.
When changing the belts it may also be time to replace the internal tip seals or re-grease your pump using Powerex's IP616201AJ Grease Gun Kit. It is also recommended to change the air filter and clean the blower fan and compressor fins.
This is an OEM 3VX belt manufactured by Powerex. This is only used on the unenclosed scroll models. If you have an enclosure on your scroll compressor, instead you might need BT010701AV.
