Does PayPal have an ACH?

I'm curious about PayPal's payment capabilities and I've heard of ACH transfers being a popular and efficient method for electronic payments. Given PayPal's widespread use and reputation in the digital finance world, I'm wondering if they offer ACH functionality. Does PayPal indeed have an ACH system integrated into their platform? If so, how does it work and what are the benefits for users? Understanding this could potentially enhance my payment options and streamline my financial transactions.
