I bought my system WAY BACK WHEN from a huge air compressor biz in Royal Oak MI .... the service guy who hooked me up to the 3 phase system I had raced again at Detroit Dragway .., we grabbed a big pizza and had a BS session.

ON THIS TOPIC .... jsta the other day he had a service call at a big gas station/auto repair shop..... their compressor was acting up - no air volume..., lots of stops and starts ....

yadi yadi YADA .... the air tank had NEVER HAD BEEN DRAINED !
