{"product_id":"castair-dryer-pump-100-mounted-dp100m","title":"Castair Dryer Pump 100 Mounted - DP100M","description":"\u003cp\u003eThe Castair DP100M is the mounted version of the DP100 dryer pump kit — a complete dryer bypass assembly for Castair refrigerated dryers, configured so the dryer is physically mounted rather than floor-standing. Where the DP100 leaves the dryer placement to the installer, the DP100M includes the hardware to mount the dryer unit in a fixed position with the bypass plumbing integrated. This is the right choice when you want a clean, organized installation with the dryer secured rather than just plumbed in-line and resting on its own.\u003c\/p\u003e\n\n\u003ch2\u003eDP100 vs. DP100M — The Difference\u003c\/h2\u003e\n\u003cp\u003eBoth kits serve the same function: they install a Castair refrigerated dryer with a proper 3-ball valve bypass, allowing dryer isolation for service without interrupting compressed air delivery.
