Flexible installation 21x21 bathroom heating fan J-421A

The installation size of JLA’s 21 x 21 bathroom heating fan is the same as that of ordinary bathroom exhaust fans. It is easy to change and has three installation methods: ceiling, window and wall-hanging type. It is small in size and light in weight, and is highly adaptable to different bathroom environments. The single motor and heating module can ventilate and heat the bathroom and quickly increase the air temperature in the desired space. The air outlet has a wider swing angle and better effect. The air outlet is equipped with a non-return valve ducting pipe connector to prevent strong wind backflow noise, odor, and keep out pests such as mosquitoes. The appearance is simple and stylish, and is waterproof and fireproof. It is operated by a control panel or a wireless remote controller, with four functions, including a ventilator, fan, heater, and dryer.
