{"product_id":"castair-refrigerated-dryer-accessory-rddm","title":"Castair Refrigerated Dryer Accessory - RDDM","description":"\u003cp\u003eThe Castair RDDM is an accessory for Castair RDD series refrigerated compressed air dryers. Based on the M suffix in the part number, this component is a manifold or mounting kit — either a bypass manifold assembly for servicing the dryer without shutting down the compressor, or a mounting kit for integrating the dryer into the compressor installation. Castair offers similar bypass and mounting hardware for the RD series (the #DM75 and #DP100 kits), and the RDDM serves the equivalent function for the RDD series dryers.\u003c\/p\u003e\n\n\u003cp\u003eA bypass manifold is a practical addition to any refrigerated dryer installation. It allows you to isolate and bypass the dryer for service, refrigerant recharge, or component replacement without shutting down your air system — important in production environments where the compressor cannot be taken offline during business hours. Contact us at 866-217-0063 to confirm whether the RDDM is a manifold kit, mount kit, or another accessory for your specific RDD model.\u003c\/p\u003e\n\n\u003ch2\u003eWhy a Bypass Manifold Matters in a Shop Installation\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eService without shutdown:\u003c\/strong\u003e Isolate the dryer for maintenance while the compressor continues supplying air to the shop — critical for busy shops that cannot afford downtime during a dryer service call.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant recharge access:\u003c\/strong\u003e The dryer can be bypassed while the refrigerant circuit is serviced, without depressurizing the entire air system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWinter bypass option:\u003c\/strong\u003e In some installations, the dryer is bypassed during summer months or during specific processes where dew point matters less — a bypass manifold makes this practical.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatible Equipment\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCastair RDD series refrigerated compressed air dryers (RDD40, RDD50, RDD80 series)\u003c\/li\u003e\n\u003cli\u003eConfirm exact compatibility with your RDD model by calling 866-217-0063\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCastair RDDM manifold\/mounting accessory kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eFull contents, connection sizes, and installation instructions available by contacting us.
