MaxxAir 00-07500k MaxxFan RV Roof Vent 12V - Smoke / Remote

This roof vent's 10-speed, 12-volt fan and built-in thermostat give you maximum control over ventilating your motor home or enclosed trailer. The lid features a built-in rain cover so you can use your vent in all kinds of weather. This roof vent gives you a high level of control over ventilating your RV or enclosed trailer. You can set the fan's direction to exhaust hot, stale air or pull in fresh, cool, outside air. You can also adjust the fan's speed to control the volume of air movement. Or you can set the thermostat, and the fan will automatically vary its speed to keep your trailer comfortable, freeing you from the trouble of constantly adjusting the fan yourself. With two lifting arms, the MaxxFan roof vent provides sturdy support for the lid. It's strong enough to handle high winds and to stay fully open while you're driving. Unlike typical vents that use just one arm, this one won't annoy you with fluttering sounds or make you worry that it might blow away. This fan is controlled remotely or from the ceiling controls. The adjustment knob rotates to allow you to raise and lower the lid. You can lock the knob when the lid is fully opened or closed, ensuring that it will stay in position.
