If your vent still runs but the airflow's gone weak or noisy, a fresh, balanced blade gets the cabin breathing again in about ten minutes, no rewiring, no touching the roof seal.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is the genuine Dometic K1137-00 replacement fan blade for Fan-Tastic roof vents, an 11-1\/2 inch clear blade that drops straight onto the motor shaft of your existing vent. If your powered vent still runs but the airflow has gone weak, wobbly, or noisy, the blade itself is usually the culprit, and swapping it is a quick fix that gets your cabin breathing again.\u003c\/p\u003e\n\u003cp\u003eIt fits the Fan-Tastic and Dometic 1250, 2250, and 7350 model vents. Those are the powered roof vents you'll find in a lot of RV galleys and bathrooms, and in plenty of boat cabins and heads too, anywhere a 14 by 14 inch roof vent is pulling stale air out and drawing fresh air in. Not sure which model you've got? Look for the model number printed on the fan housing or in the vent's paperwork, and confirm the blade you're replacing measures right around 11-1\/2 inches across before you order.\u003c\/p\u003e\n\u003cp\u003eFan blades take a beating over the years. Constant vibration, heat cycling, and UV exposure through the dome slowly make the plastic brittle. Eventually a blade cracks at the hub, warps out of true, or throws itself out of balance, and you end up with a fan that rattles, hums, or barely moves air even at full speed. Sometimes a blade tip catches the frame and chews itself up. When that happens you don't need a whole new vent, you just need a fresh blade.\u003c\/p\u003e\n\u003cp\u003eThis one's molded in clear plastic, which is what the 1250, 2250, and 7350 shipped with from the factory. The clear blade lets daylight pass through the dome instead of casting a big shadow across the ceiling, so your vent still works as a skylight when the fan's off. More importantly, a true, balanced blade moves the air the way the motor was designed to. You get the full pull on exhaust and a clean draw on intake, without the drone of an unbalanced fan spinning behind your head at night.\u003c\/p\u003e\n\u003cp\u003eOn the water, these vents do real work. A powered roof vent over the galley clears cooking heat and steam fast, and one over the head keeps the whole cabin from going stuffy on a hot, still day at anchor. A tired blade quietly undercuts all of that, moving a fraction of the air it should while the motor works just as hard. Dropping in a fresh, balanced blade brings the airflow back without touching the wiring or the roof seal, which is exactly the kind of low-risk fix you want on a boat where every hole in the deck is a potential leak.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward and takes about ten minutes with the vent open. Kill the 12 volt power to the fan first so it can't spin while your hands are near it. Open the dome, back off the set screw or clip that holds the old blade to the motor shaft, and pull the blade straight off. Slide the new K1137-00 onto the shaft the same way the old one came off, seat it fully, and snug the set screw down so it can't creep. Spin it by hand once to make sure it turns freely and clears the frame and dome all the way around, then restore power and run it up through its speeds. That's it.\u003c\/p\u003e\n\u003cp\u003eA couple of things worth knowing. This is the blade only. It doesn't include the motor, the dome lid, the lift arm, or the vent frame, so if your motor's the part that's failed or your dome is cracked, you'll want those pieces separately. It's sold as a single blade. And because it's sized specifically for the 11-1\/2 inch opening on the 1250, 2250, and 7350, match that number to your vent rather than eyeballing it, since a blade that's even a little large will bind against the housing. Get the right size on the shaft and this is one of the easiest, cheapest repairs you can make to keep the air moving through your rig or your cabin.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eGenuine Dometic K1137-00 replacement fan blade for Fan-Tastic powered roof vents\u003c\/li\u003e\n  \u003cli\u003eFits Fan-Tastic and Dometic 1250, 2250, and 7350 model vents\u003c\/li\u003e\n  \u003cli\u003e11-1\/2 inch nominal diameter, sized to the factory vent opening\u003c\/li\u003e\n  \u003cli\u003eClear molded plastic blade lets daylight through the dome so the vent still works as a skylight\u003c\/li\u003e\n  \u003cli\u003eActual blade size 11-3\/8 in diameter by 1-3\/16 in height\u003c\/li\u003e\n  \u003cli\u003eBalanced blade restores full exhaust and intake airflow without motor drone\u003c\/li\u003e\n  \u003cli\u003eSlides onto the existing motor shaft, held by the original set screw or clip\u003c\/li\u003e\n  \u003cli\u003eBlade-only replacement, so you fix the airflow without swapping the whole vent\u003c\/li\u003e\n  \u003cli\u003eSold as a single blade\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Dometic reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhich vents does this fan blade fit?\u003c\/summary\u003e\n    \u003cp\u003eIt fits the Fan-Tastic and Dometic 1250, 2250, and 7350 model powered roof vents, which use an 11-1\/2 inch blade.
